85 Trans Am wont run
 

I cant figure out whats wrong with the car. I put new gas in the tank thinking that the five year old gas in there would be causing it to not run, but it still doesnt work. its got a new fuel pump, and filter. it will start up but as soon as i give it gas it cuts the engine out. any ideas?

Could be a number of things. Check your fuel pressure, also if you ran the bad gas through thr carb it may be gummed up and in need of a rebuild..

Given the level of detail you provided, I can definitely say that something is malfunctioning. Recommend you fix it.

(some more detail, like what mods and whether it's injected or carburetor, might help...)

where are you located?

I'm 90% sure this is a friend of mine...Ya'll though MY T/A was bad.... how about you wait till I get over there to look at it. I told you already, its probably the TPS or the MAF. It could also be the timing, or it just needing a tune up. When I have time (wed) I'll stop over with my timing light and multi-meter and we'll figure it out. but in the mean time get the car registered and insured, cause without being able to drive it I can't test it under load.

So this is an injected car then? Definately sends the line of diagnosis in a slightly different direction.

Yeah, what type of top end is on the car??

its a TPI 305 supposedly... So that tells me that the engine doesn't belong in that car, know the kid he bought it from, its a hack job + some. I'm going to have to go over every inch of wire and test the signal from a quite few sensors. to figure out wtf is going on...actually bout to get on the phone with him now

....was a carbie car. has the 86 accessories on it, with a TPI top end, can't even start to understand the issue because the fuel pump gets no power. on top of that, the wire harness is beyond hack-job the GFX are not right. the car its self used to be white and now its purple. it ain't worth the $110 he spent on it

Let me preface this by saying I've never worked on a TPI setup before so this is purely a guess.

If it was a carb car, the fuel pressure may be way too low for an injected setup. Is it an EFI fuel pump?
