I'm having trouble with my fuel system

[M.A.Durrence]

I got water in my intake a couple of days ago, and since then I've cleaned/refab my motor. Now the only thing that i can find that's wrong is I'm not getting any fuel through my fuel lines. I've checked my fuses, replaced my fuel filter, and checked the fuse panel for power, and everything seems to look okay. If anyone knows any solutions, I would be grateful for your help.

stupid question but can you hear the fuel pump prime when you turn the key to the on position?

 

[M.A.Durrence]

no, but i don't really ever remember hearing it before either.

 

[outtamymind]

listen for it. and yes it will hum when you turn your key to the on position. you don't remember hearing it because most peoples radio's are on or talking to someone, but try it and report back.

Fuel Pump Relay.

 

[M.A.Durrence]

nope, no humming

 

[outtamymind]

then start looking along the lines of why your fuel pump isn't working. could be a fuse, the fuse pump relay, could be a bad ground to your fuel pump, could be your fuel pump as well.

I vote fuel pump relay, it fits in the spot right next to it and it looks right but wont function. So either the relay is bad or its in the wrong spot, me and Tom switched ours for a night on accident and were baffled till morning when we had light.

just thought of this when i opened the thread...that night was FAIL!!! but my car started the next morning


make sure your relay is in the right spot! you can actually put it in slightly off and it wont work....

mcarlson....i'm having the same exact problem, did you ever figure it out...working on a 08 that was hit in the front end, all fixed but the fuel pump will NOT come on with the key....i can jump it and it fires right up....i know its not the relay.
There is no power coming in to the relay on the low amp side, there is 12volts on the switched side.
My question is where does the voltage come from that turns the relay on?? ecm?? ignition?? Is there another relay other than the one right next to the fuel pump fuse?? Be easy on me, i'm just a "boatguy" and we're about 15years behind the automotive industry...haha, thanks in advance.

I don't know much about a situation like this... but I'm wondering if the Cobalt has a built in system where if there is a bad front end wreck and the air bags deploy, it will also kill the fuel pump so that if a fuel line is ruptured, it doesn't continue to spray all over the engine bay.

Don't know too much about that though... as I've never been in a wreck like that... and never paid attention to anyone that was.

I know some older Ford's had something like that, though. There was a switch in the back of the Taurus's, iirc, that you had to flip to get power to the Fuel pump again. I don't THINK there is a switch in the Cobalt... but there might be another fuse/relay that gets popped. Iono.

I believe emergency fuel cut off is actually mandatory now a days. I know of a lot of cars with said cut off. weather it is a switch, relay or fuse type system.

its called an inertia switch and im certain the cobalt has one

Horray Brembos!
