You may still have a fuel pressure problem possibly caused by a bad fuel pressure regulator (FPR) or fuel pump resistor. To properly test fuel pressure an automotive fuel pressure tester should be hooked up to the Schrader valve. A GTP will read 45 - 55 psi with vacuum connected at the FPR. With vacuum disconnected at the FPR and ignition in the run (fuel pump prime) position it should read a solid 48 - 55 psi, normally around 52 psi or better.

If you are losing spark the possibility is a defective crank position sensor (CKPS) or ignition control module.

Finally, you could have a worn out ignition switch assembly cutting off or not making IGN MAIN 1 & 2 12v to the starter, ignition circuits and fuel pump relays.
