HELP!!! 1991 Trans Am 305 TPI, dies after warm-up. I have brand new accel 19lb injectors.(all tested @ 14.9 ohms)

I have also recently installed a new gas tank with a 255lph fuel pump. I am still using the stock FPR, is it possible that too much fuel pressure is causing the injectors to fail after it warms up? Or will there just be some over run at idle?

Thank you for ANY help!!!!!

Frustrated, and holding a lighter,

Chris.

 

Do you have a fuel pressure guage? Hook it up to the fuel rail and see what it reads.
And what happens when it "dies"?
Does it just quit? Or does it run really rich?

 

The car just dies. It will turn over, but will not run or fire. (sometimes a little sputter)
This is only after it warms up.
I don't have a preasure gauge, but will get one soon.
Damn near everthing is new now. Is too much fuel bad or hard on the injectors? (other than running rich a idle)


Sometimes when it first dies, you can get it to start, but it will only idle like crap, and as soon as you even touch the gas it will sputter, miss, ping and shut down. Then it won't start untill it cooled down. (a long time. . . . . )
