I found the ground wires and followed them up as far as I could to the dash/firewall/wherever they go and never saw where they all connect together. Do you have any pictures of what you did?

I went up about 18-24 inches and never saw them all spliced together. A couple of them connect to each other here and there, but I didn't see them ALL connected together anywhere???

I think my ECU has burnt up no more than two days later the car started runnin like crud again . If I touch the ECU it is really hot like if you held your fingers there it would burn you a little . Anyway Regrounding the wires did help I just think the ECU was a gonner in the first place now I have to find another one and thats gonna suck cuz I was already at the salvage yard and of the two cars there they were both taken already . So ill have to resort to looking online now .

Also I now my starter is bad but after I start the car it revs up then it drops back down and die's what cause's that ?

Mine used to do that until i adjusted the tps.

Did you actually check to see if the pump is flowing full pressure up to redline?

Did you change your fuel pump sock and fuel filter?

It's obvious according to your gauge it's NOT getting fuel, so i would look there first.

I figured out what is was the other day I made one of those homade ORFACE"S you know in the boost sensor hose well they said to use appoxy to make the now size hole well what happend was the appoxy melted shut after is was on the car . So the ECU is fine I know for a fact now its the ORFACE just gotta make the hole a little bit bigger on the old orface cuz its not big enough and the car will bog at . Yeah my TPS works fine tested it the other day . I will check out the pump when I can being as I dont have the proper things to check it as far as I know I need a pressure guage not sure what else . Its the stock pump I used to have a walbro in there but I found out thats a bad thing on an N/A heheh . I am also kinda wondering if the walbro pump could have made the FPR go bad ?

I redid the orface and now if I work up the rpms slowly it will be okay but if I step on it . The car starts jolting in and out of bog ?

pull off the kick panel (with three plastic snap things), then remove the plastic scuff plate on the door jam, then left the carpet up.
