Default Fuel pump failure?

Good day.

Does anyone know the symptoms of fuel pump failure?

I ran out of gas (I think) today, and now that it's got some in the tank it won't start, and I have the check engine light on.

I know the pumps overheat and fail as gas provides cooling for them, and running with a low tank may risk overheating.

Wondering if I just cost myself a bunch of money.

Anyone have any pointers or advice?

If you have the engine fault light on, you can retrieve the fault code and it will help diagnose your problem.

How to retrieve fault codes.

Thanks, Crewzin.

I abandoned it at a gas station and am at work, so will check in the morning, as I work night shift tonight.

You're awesome.

Yes a fuel pump problem could trip one of many, many codes. Among them are p0169 to p0194, p0230 to p0233, p0313, p0460 to 463, p0628 to p0629 and the most likely up to that point would be the p1172. There are probably more and more of them, but I stopped looking at that point.

Still won't start.

Code is 0522, oil pressure sensor problem.

Wonder why it won't start.

At least the fix for the sensor shouldn't be too hard.

It won't start because the oil pressure switch triggered the ASD (auto shut-down relay) and it shut the car down to protect the engine. Thats what it's there for. The fuel pump going bad and a few other things that I don't recall right now will also trigger the same responce from the ASD, again to protect the engine. The ASD is in your PDC (the fuse box under the hood just in front of the master cylinder). Disconnect your neg. battery cable before doing anything in the PDC. Usually you can just remove and then replace the ASD (the old one back in) and it will reset it. Normally you don't have to buy a new one. If it was mine I would replace the fuse # 20 while you have the PDC open. It's the fuel pump/auto shut down fuse. It WILL trigger the ASD to shut your car down if a problem with the pump or fuel pressure is sensed. Its a 20 amp yellow fuse. Since you say you might have ran out of gas I would replace it just for giggles.
