I just got my car running it is a305 with tpi. The car was not running when I bought it but I diagnosed that I needed a fuel pump after installing the pump it started and ran fine for one whole evening I would start it drive it a little bring it back and look it over(it had been sitting for 10 years). Each time everything looked good except for the normal leaks. The next morning I went to start it and it took forever to fire. I did a fuel psi check the psi was fine at idle but it dropped to 0 just seconds after it was shut off. I thought that I might have a injector that isn't seatting.
