1999 ZR2 fuel pump whine????

[jtbandy]

I changed out my fuel pump a few days ago because when I turned the key on there wasnt that few seconds whine of the fuel pump...so.....I changed out the fuel pump......still no power to it.....so I found the relay under the hood in the box and swithed out the relays....still nothin.....so I slammed the hood and was giveing up on it,but.....I thought I would try once more....turned the key....heard the whine it started......this was a few days ago.....now...I got about 30 mile4s from home...same thing. Fuel pump isnt coming on.....

Any Ideas????????

try wiggling all the wires under the relay and see if that helps. It just sounds like a loose conection somewhere under the hood

Thanks...I will give that a shot...I forgot to add.....I checked the voltage at the connector wrer it plugs into the pump.....I'm getting 12v for a bout 2-3 seconds when I turn the key on...then it goes to 0...I assume the is the charge up voltage.....but still wont come on. And...I hooked up the old pump straight to a battery and it works.....so..I pluged it up and turned they key on and it wont run either...so..I will give the wingleing a try...

Thanks for response.....

That is the prime voltage.

It primes the pump for two seconds and then shuts off.

sounds like a bad connection if you can hard wire it and it pumps, check the connections

do you have an alarm. some alarms shut off the ecm power while others just stop the starter from turning. my wifes 1999 taurus shuts off the ecm.

[jtbandy]

So whats the easiest way to hard wire it?? And if its getting voltage power to prime..why isnt it priming?? Sorry...first time dealing with pumps on a S-10..

[jtbandy]

No...I dont have a alarm....but I was reading something about pass lock?? Something about if I have the wrong key?? But my key doesnt have a chip in it...And I been using the same key for 3 years now....

How much fuel do you have in the tank.

From what I have heard, you have to have it up to a certain level in the tank to prime it for the first time.

I had just put about 10 gallons in it....I have been driving it for about a week now since I put the new pump in...Its beyond me....I have tryed everything...

Thanks for the responses

your pass lock is the problem.

[busa_4]

are you saying you have pass lock or you dont know? i cant remember the exact name of the system. maybe one of the other guys would know.

[jtbandy]

I'm not for sure...its in the manual....how do you reset it??

[busa_4]

i dont think you can reset it. you might have to bypass it.

[jtbandy]

Well....same story again...I was about to give up on it...tryed it once more....turned the key....pump charged up..it started...now my gage doesnt work...and when I started it it had a REALLY bad ticking....And there was alot of condensation coming out of the tailpipe...but... I let it run for awhile and the ticking went away.....I dont have a clue what is wrong with this thing...BTW..I have a sevice engine light on now....

Thanks again for the responses
