its a 96 eclipse 2.05 speed ,about 4 months ago it stalled and would not restart i put a new coil,crank sensor on it (that checked out bad) and nothing. while i was working on it i cleaned up the wire harnes from a bad motor swap someone had done.then all of a sudden it started and ran great. yesterday i was driving and it quite running.then 5min later started back up and ran fine till this morning when it quite.now it wont start back up.every once in awile it will run for 5-10 sec. and die.it was gas,was power to coil , crank&cam sensors test good ,   ?would low fuel presure prevent it from running ?

ok 1 more question could the fuel pump shut down the signal to the relays (asd ,fuel pump) ? or the pcm?

Answer
Matt,
If the PCM detects the engine is running, and determines the fuel pump is not providing enough fuel, they PCM will turn the car off.  Usually, it'll blow a fuse if that happens.  No relays should be affected, but it would be a good idea to check all fuses and relays to confirm.
Good luck!
