car died on the road today while driving, i tried to restart it, its turning over but not starting. i'm thinking it might be the fuel pump but i was wondering if i can get some insight as to what may be the cause

Crank/no starts can be a hundred different things. Last time for me was skipped timing. Can you hear your fuel pump coming on?

[Gamesy]

i can never hear the fuel pump turn on, if that is the case, how much is one these days?

Have to do some testing!

Make sure about fuel for starters

Keep in touch!

my car still has a 1/4 tank so i know i'm not out of gas, the weird thing is it cut out when i shifted so i'm wondering if maybe some wiring got in the way of the pedal

[Gamesy]

i unplugged the fuel line on the fuel filter and cranked the car, no fuel coming out, looks like fuel pump went, i'm trying to find the fuse for it, anyone know where it is?

Next step is to confirm that you do or do not have voltage going to the pump with a multimeter. Test the harness that plugs into the pump. Positive lead goes to blue (12v from relay) and negative lead goes to black (tests ground as well). If you have 12V when you turn the key on, the pump is likely bad, if you dont get a voltage signal try putting your ground lead to a different, ground, no change then you're not getting voltage from the relay. For that you might have a bad fusible link or sometimes a bad relay. But test for voltage before condemning the pump.

When you check for voltage at the pump. Keep in mind that when you turn the key to start, it runs the pump for a few seconds, then cuts power until the car starts. So, you can't just turn the key to "run" and then go probing for voltage.

Can you hear the main and fuel pump relay clicking when you turn the key? They are up under the dash near the ECU.

The fuel pump is fairly quiet, you can't really hear it run unless you're trying.

If the key is turned on and you have voltage at the pump, but no fuel pumping out, the story is over! Replace the bad pump.

I usually listen for the gurgling of the fuel through the lines.

update:, not getting any voltage to the blue wire. on the pump, can not find the relay, tested sat the pump and at the module.
is there a schematic for the fuel pump system?

[Gamesy]

FIXED!! ****ing E/G IGN SRS AIRBAG fuse blew, i should've looked at the fuses first.

A happy ending nonetheless.

ya no kidding at least i got all my aftermarket wiring crap from the previous owner out, it was such a birds nest.

I hear you, both of mine have scary wiring under the dashes. Remote starters (that don't work), extra lights, power outlets.... EEEK!
