You check the fuel filter and fuel pump by checking the fuel pressure, somewhere around 35-40 psi. MAF and MAP sensors can be shot even if they got the right voltage coming in and out of them. The only way I noticed my MAP sensor was bad was by hooking it up to a datamaster program through a laptop and then it was still hard to tell if it was giving correct MAP readings out.

I don't know how a fuel filter is set up on 1st gen camaros. If you got bad fuel pressure then replace that first. I wouldn't think it would run more than $15.

ok, well i had checked the MAP and MAF sensors on a pcm scanner, not the little handheld one, but the big one that shops and cities use, it said only the MAP sensor wasnt working, but thats because it had no power. it does now.



how do i go about checking the fuel pressure. Im completely lost on that part. thanks!
