So i was makin a late night run out to mcdonalds last nite and all of sudden my car shut off and wouldnt start back up! I popped the hood to see what the problem was and noticed that i have no fuel pressure any more.

i replaced the fuse still no cigar

checked the plug in the trunk and it looks fine to me

I cant even hear the pump turn on when i turn the key

i bought the car with the walboro fuel pump already installed, that was about three years ago...do u think it could have gon bad??

I suck, can't read. If you don't hear it, it's either electrical or a dead pump.

if you cant hear it now, but you could before, then it is probably dead.

get a test light or voltmeter and check to see if you are getting power to the fuel pump.

or if you have a power probe, give it power and see if it clicks on.

if not, replace it and be on your way. its liek $80~ for a new walbro

dead pump. they do it for no reason, i had a walbro die in my car while it was sitting with no battery in it.

I havent checked the fuse for the relay, ill try that later today.

I have a voltmeter too so ill check for power going to the pump also, if i find ther is power then i guess ill just buy a new pump.

shit blows man, i just got the car running decent to (bad coil) not even two days later something else goes bad, lol

Right, if you got 12v at the pump plug then problem lies within the pump.

Had this prob when i was getting my wifes S13 running had 12v at the pump dropped in the Old SR F/P and it fired right up.

new pump bud. I was in the same problem, i thought it was wiring so i re-wired all my harness and rebuild my starter, and new dizzy cap and rotor. And finally i change my fuel pump and it starts like a champ!!!
