Default no spark and no fuel presure

I got a 1996 trans am ws6 that was a m6 but now a a4..I berly got the car not running .. At frist i thought it was the fuel pump and opti so i swap it out.. I get spark sometimes and fuel presure sometimes but then it cuts out for some reason.. I got a new key for the security as well .. Im thinking it has something to do with it but idk..I have it at the shop and the guy is having problems locating whats causing the short.. He check the harnes as well as the ing switch .. So mabe someone on here might have had the same problem and can help me out .. if you guys have have any ideas i wouldnt mind trying them .. Till this gets fix i cant drop my new 355 with my le1 set up in.. Thanks in advance..

This makes me think it is an electrical issue somewhere. How do you know you are only sometimes getting spark? It honestly sounds like there is a short somewhere. Check your wiring for the fuel pump since you just replaced it.

Well the mechanic has checked it with a muiltimeter and it shows it firing as well as the same as the fuel pump.. It shows fire then cuts out.. He checking the the whole harness it worse comes to worse i just might have him swap out the whole thing..The next thing hes trying is the ecm .. So i hope its that ..

check your grounds. There's nothing seems to be wrong with any of the hardware like pump or opti. This is an electrical problem.

We had 41* one day and poof winter shows up again and I'm dealing retarded cops that wrote me a second summons in less than 24 hours for tints in the same spot. Freggin hate this city sometimes lol. NYC is so damn broke, the lights are turned off on highways.
