Getting closer........

and not sure how the FI system you have works, but I agree that you do not need 2 regulators. I also do not believe that you need to run a vaccum reference either. That is a long way back to the reg and not sure you could get it to work being that far away. My LS based system works on a constant pressure and I would think you could tune yours to do the same.

I'm pullin' for you Dude!

It's good to know that you are not running a vacuum line and I too think I can just tune it to work without it.. That is what we buy efi for to begin with and then the engineers still put the crutch back into these systems that used to plague them just in case.

With problems like a blocked fuel regulator how do you go faster than step by by step to know what is the problem. Next in line is the igniton harness that may have been wrong from the factory. I say this because when I got my system it was discussed with the tech at Accel and he had noted that some were made with the wires in the opposite side of the connectors. I left mine alone just incase it was actually tested on an actual test bench and even though the wires don't look right they are in the place that works?

Next week will be interesting if I don't get somewhere the rest of the week and weekend and I get the EMIC here to go over my system. I know I am getting a big spark but it might not be in any specific program for all I can tell right now.

Thanks again for the support !!!

I just got done working on my Racepak problems with Donny at racepak and I am so impressed with everything I can't say enough good things about how they operate.

I have all of my gauges working and my fuel to the engine now I just have to go thru the distributor timing and ecu configurations one more time to make sure it is all good and then see if it starts or move on to the next step of getting this car running.

If Accel could do the same logging on to my computer that racepak can do it would make their job a breeze and take any errors a person could make tight out of the equation.

No leaks in the new fuel lines and I have 84 psi fuel pressure and am going to start adjusting it down to 60 for starters and then set it when it is running unless someone thinks I should leave it high until it starts?

I am getting more excited than ever now!!!

congrats Jim! just saw all this progress and it looks awesome! keep it up!

Glad you figure out some of your problems. I wish I knew anything that could help you. But I'm rooting for you This is the first post I look for when I sign on . Good luck. Wayne

Here a couple pics of the dash display working.

I think I have all the vitals monitored that are important for start up and once they are good I can change them to what's really important like acceleration, cornering and stopping.

It is going to be nice to not have to guess by the seat of my pants.

There is so much this thing can do I will be learning for a long time before I ever get to use it all.

fuel pressure. 84 psi is way too high. If the regulator that came with the kit limited it to 45 psi then I would dial it down to that number.

Dash looks very cool

I couldn't wait to take a pic of the dash working before I set the regulator. 84psi is what the fuel pump puts out at full open. I turned it down to around 47psi before I ever tried to start it figuring that it would only lose a few pounds when running.

I know that I am getting fuel for sure now.

The system held itself at 37 psi after 12hrs of sitting overnite which seemed pretty good ?

I've had 2 friends over to help that are both knowledgable about engines and the normal routine and when we went over the distributor install we found that I was only going to the edge of the red light going off the first time and not going to the second red light going of like the instructions said.

However, we looked at the instructions given to me by RSX302 and he stopped at the first red light and didn't go to the next redlight and off.

I have tried it both ways.

There is heat coming from a few cylinders but not all and some are black #1 and some just have fuel on them. I know it is not firing every time it comes around because the timing light is not firing. We have had it fire at the #1 at 12 degrees btdc which would be good for crank timing but it isn't consistent.

I still don't think the ecm is loaded with the correct program? I have tried to do the plug n play but the laptop says there is a communication problem when trying to do it that way. When I was on the phone to Accel we just loaded the pogram from the ecm and went to f7 and filled out he parameters on the system screen and he said I should be good to go. For some reason it has been the concensus with everyone who has helped me is that it is not the right program for the timing.

I know I am doing something wrong ,but what?

We double and triple checked to make sure that we have enough voltage at the ecm when the ignition is turned to turn the car over and we have 11.5 volts so that is probably not the problem. The ecm will shutoff at 8.5 volts according to the manual.

So I am going to put the car together the rest of the way this weekend and I have a tuner/installer coming next week to get me going unless I can figure out what I am doing wrong or what is not working in the system. He is bringing a backup distributor harness just in case the one from the factory is one of the bad ones that they had problems with back in 2005 when I got my unit. He is also bringing his laptop since it seems to be a communication problem with Vista. The parameters of the program don't include Vista but you would think it would work but hat is Vista and it does have problems I have heard for other stuff and it sure has problems with other things ,that's certain.

So enough is enough for now on the engine and it is time to assemble the rst of the car to drive and hopefully when the tuner gets here we will get it running and be able to go for a drive pending my insurance agent getting back to me soon enough.

I hope it all falls together at the same time and I can make it to RTTH.

It is possible I know it is.

So if you have any ideas I am all ears.

Thanks.

hey jim who are you using for insurance?

[Jim Nilsen]

hey jim who are you using for insurance?

Continental Western ins. for starters and then when I get to the point of track days and autocrosses I will find another to do the honors. But for now I just have to have coverage for driving it on the street.

Could the coil be bad?

[Jim Nilsen]

Could the coil be bad?

There is plenty of spark it just isn't getting enough of them at the right time. A couple of plugs are black others slightly fired and a couple are just wet with fuel.

I truly believe it is a Vista/usb driver communication problem. The program from Accel does not include Vista as a choice yet. It should work but it is running me around in a circle and won't let me plug n play a program into the ecu from what I can tell and the upload from ecu program really doen't seem to work either.

I have help on the way tommorow with an older laptop with a 9 pin input and some other usb connections and drivers. I am hoping that it will be the solution to the problem.

Thanks for racking your brain for me. This is getting so close and yet so far away. It has to be something simple now and not anything mechanical I hope.

Thanks again.

It's been a long day and I still don't know what is the problem.

I had some really good help from Matt(Bow tie 67) and we went over just about everything we could and still can't find what is wrong yet. We have checked wiring , timing the distributor, even tried his laptop to communicate with the ecu and things seems right everywhere and we are getting big spark but 4 cylinders are getting hot and 4 are cold and seem to have no fuel. It seems to be a program problem but what?

We went over the harness to the dual sync distributor and it did not seem to be right so we switch a couple pins and it seemed to do better. The ignition box has the red light flashing like it should indicating that it isn't the problem.

The schematic for the harnes doesn't even have the same color wires as the harness but we followed the connections and redid it so it matched the schematic. It did seem to do better but no starting.

I have an EMIC from Accel coming sometime next week to help and he is bringing a harness that he knows works from a running setup.

I still wonder about a communication problem between the ecu and the laptops because of the com port errors that always come up. My laptop after a couple of tries will go to the screen and say it is communicating and his would do the same.

We tried batch fire instead of sequential and still no luck.

I wish I had the video that Accel has to do the install but I don't. It was my mistake to not demand that they send me one when I was on the phone earlier in the week and it would have been nice if they would have offered to send me one but alas that didn't happen.

If there ever were instructions that don't make sense Accel can make them.

So far at least everything still seems to be working and no burned up parts or non working ones just parts the seem to not be setup or timed right.

At least I am getting to be more familiar with the tools and the order to do routine maintenance the fastest.

Tommorow will be a day that has progress in a different sorts. I am going to go over all of mechanicals and make sure they are tight and working and then put the sheetmetal on.

If things fall into place I can still make it to RTTH with the car, if not I am riding shotgun with Matt and will see you all there.

This is the last time I should see the fenders on the wall and be able to get a pic of the engine from the angle you see them in the pics even if things don't go right with starting.

If cars have souls maybe this one wants to start up and head out of the garage with no delays. If it all comes together right I could have it start up and then open the door and go for a drive and tune Tuesday or Wednesday.

This is as much suspence as I can handle and will be almost as relieved to get it going as I have ever been next to hearing my cancer was gone.

Let us PRAY !!!!!!!!

I've done several harnesses with GM pcm's,I did one and had the same exact issue(one bank had no injector feed). It was a wiring issue,you need to check it with a volt meter.If there is no voltage at the injector(is it missing ground or hot)trace it back,is there any output from the pcm,if not it has to be the pcm or a sensor not telling it to fire(crank trigger,cam sensor in the dist.)

I'm not familiar with Accels system,if you had the time I'd try to talk you into putting LS1 electronics on there.I ran my Hemi off them and worked great,I think a SBC would be easier to set up,and way more reliable. Ron

[Bow Tie 67]

Jim,

I sent you a long PM, but think I decifered the damn instructions. Rons idea on checking the injectors is a good one, basically the same thing I was suggesting with a noid light. First off I would try what I suggested in the PM. If it works well post it up on this thread.

Thanks Ron, I will have to try the voltage check. I do know that from one time to another I have had fuel at every cylinder but it has been as random as the spark to each cylinder.

The sad thing about all of this is that when I have talked to Accel and was asked if I had the video to do the install and I said no they didn't offer to send one and I unfotunately wasn't thinking past my problem and didn't demand it.

This whole thing is getting very disappointing from the Accel side of things.

Thanks

[thedugan]

Are you using the Accel Dual Sync? Can you send over the instructions that Ron sent you

[EvilCamaro]

love the dash
