LT1 Optispark/timing issues

[HectorM52]

You need three things go get the engine to run.

Air
Spark
Fuel

Hopefully you're getting air. Is the throttle opening?

Spark - are you getting it? Pull the wire between the coil and opti from the opti side (you do have this wire installed, right?) Have a buddy turn the motor over, put the end of the wire near something grounded. Is it sparking?? If so, at least you've confirmed you're getting spark.



Fuel - pull the four bolts that hold the rail to the intake. Pull off one injector pigtail. Put an old gatorade bottle or something under this injector. Now get you a couple test lead wires. Put one on the positive terminal of the batter, one on the negative. Put them on the injector pins. Have your buddy turn the key to "on" but not start. This should prime the fuel pump. This should confirm at least you're getting fuel.



Personally, I think the opti gets a bad reputation. Have personally never had an issue with one. Though I agree the unvented design was silly.

Run through the "simple" steps and confirm the basics.

Could you post a picture of the engine and opti as someone might spot something.
