thats gonna suck. ok im gonna run out there and check it

 

Try swapping in a known good relay before you spend money on anything.

 

but he said he could hear the FP...
Or does the fp get run off of something else until the motor starts, and then put on relayed power?

 

ya no pressure, well a little but not what 40psi would do. so im gonna pull the pump tomoro and look at it. cuz the lighting in my shop SUCKS. especially if im under the jeep. do u think a relay could cause it??? like ^ said. but i think if it was a bad relay it wouldnt make any noise when i turn the key....

 

I guess it wouldnt hurt. Maybe bad contacts in the relay not letting enough current through.
Easy test at least.

 

so would i need a voltage tester??? i dont have one... i am pretty new to mechanics like a year or so but cant get enough. so i dont have all the tools yet. or could i just move around the contacts a bit and plug it back in to see?

 

no, hes saying to take out the fuel pump relay (ill look in the FSM real quick and tell you what one it is) and switch it for another one and see if it fixes your problem.
does your AC work?

 

im not sure if the AC works. never had to use it. i live in the rocky mountains at 7522 so if i get warm i just roll the window down. how would that effect fuel pressure?

 

trying to think of a relay to swap.
Im assuming your aux fan works...
Swap A and B
Relay center under the hood, passengers side

 

aux fan does work. im headed to the shop right now to check. (fingers crossed)

 

yup, swap them and try starting it.

 

it started for a sec then died. it did that like 4 or 5 times but then quit starting

 

hmm...
but didnt you say it was doing that before?

 

ya but it would only do it like once every 20 tries. maybe it was just a last "umph" from the pump.

 

Im thinking its the pump... Kinda wish you had a multimeter though.
