92 camaro rs 3.1l (191)

Got the car for 700$
had lose of power replaced the cat and pipe. (no muffler)
didnt start after that. Next day it started.
Then i didnt again. just cranked over. pulled the spark plugs regapped them. Started right up. went to flip a u turn in my yard car died.
Replaced the o2 sensor then it would only start with foot on full throttle and when you let off the throttle it died. Removed the IAC sensor started right up idled for about 4 minutes then choked out. Wouldnt start again.
hours later got it to start with the foot on throttle about halfway. nothing unpluged the MAP sensor and nothing.
Now all it does is crank over doesnt start.

Any help would be greatly appreciated because im completly stumped right now.

 

Is it just me or is this getting to be a very common post...
To the point... Swap out the fuel filter and check fuel pressure this is the best place to start.

 

Or you may have a VATS problem. You could do a search for the VATS bypass forum and do what it says. It's an easy fix, but compromises the security feature. With these cars not having these type of parts readily available anymore, this might be your best bet.

 

both of these come back to the same thing. Fuel pressure (Or lack of it.) Buy/rent/borrow a fuel pressure test gauge.

let us know what happens.

 

I'd say VATS or fuel. And the VATS does kill the fuel. Just not the fuel pump. So that test might not be worthwhile. You should be able to hear the fuel pump every time you twist the key, unless the battery is dead. Sometimes easier with the door open. Always easier with the radio off. Happy hunting!
