i just got my 1995 saturn sl2 , but it wont start. i crank it and it turns over ok. it tries to start but just doesnt, when i hold the gas down to the floor it starts for only a second and shuts off. ive replaced ignition module coil packs and plugs, still nothing. i check the fuses under the hood and none seem to be blown but the only one i can remember is reallythe injectors i couldnt find the fuel pump fuse. the gas gauge is reading a little below a quarter of a tank. im lost any ideas people

acculty having WOT at startup really only works for carburetored cars. infact, in GM/Saturn car if the computer see WOT at startup it will disable the injectiors and spark and will go into a "clear flood" mode as GM calls it.
first do you have spark? pull the wires off the coil packs and have a second person crank the engine, there should be a spark tower to tower on both coils, if not check the CPS
do you have a signal to the injectiors? use a noid light to test this
do you have fuel pressure? check with a fuel pressure tester.
F/PUMP fuse and relay are in the IPJB(fuse box under the radio/HVAC behind the passager kick panel)
also check BODY, CHIME, PCM I, PCM B, and DIS fuses

ok i checked all fuses which were all good, then checked spark between the coils which was good. i check the fuel pressure which was reading at 41 psi so thats good. then i check the plug wires which they were bad so replaced them and still no start. im getting spark and fuel and still no start. wat else is there?

when did this problem start/what was the cause?
test for pluse to the injectiors with a noid light, check compression, check the order of the sparkplug wires, check air intake system for resrictions

i bought the car like that so i dont know what happened to it. after cleaning the plugs back off because they had gas on them, it sounds like it wants to start more than ever. it sounds like it starts but has no fuel to keep running. could it possibly need a regulator? or crank sensor
