Not the problem, he already said that there is no fuel pressure at the rail.

finally an update!!!

so i just checked the fuel pump, when the car is keyed on, it does not prime(makes sense)

of course i need to figure out if its the pump, or something else...

i checked all the fuses on the car, all are good (the diode under the hood is missing, but apparently its not used?)

so the wiring harness for the pump has more then 3 wires... (sense its the fuel level sender as well)

so which wires are for the fuel pump? (so i can check voltage) i tried to google it, but got lots of junk...

and if there is no fuel pressure will the car continue to try and prime? or does it click off after a few seconds no matter what? (IE do i have to keep keying the car?)

i have easy access to the fuel pump relay module thing in the fender near the CIA(the front bumper is off) so if the pump is getting no voltage, that will be next!

Thanks for all help guys! you've really cut back on me pulling my hair out!

nother update!

fuel pump is NOT getting power, not even a volt!! (so i dont have to drop the tank! yeah!)

checked the FPM, wich is behind the wheel well next to the fuel cutoff switch. it reads ~.056 volts.... ive seen that if its above 10.5 the FPM is damaged... so its super low...

however the ONLY voltage to the FPM is a very clean 6V... i thought it was supposed to have 12V?

ive pulled the CRM? (the thingy with the fuel pump relay, fan relay etc...) but would rather NOT drill out the gromets to find its ok...

does anyone have the pinout for the CCRM?

i might just say F-it and grab a haneys etc... type manual.

Thanks!
