My 2003 Pontiac Sunfire won't start. The car will turnover but not start. Anyways, I believe it is the fuel pump. Is it easier to buy the repair kit and repair the current fuel pump or should I buy a whole new fuel pump? What's the difference?
Thanks in Advance!

I don't know if this makes a difference but it was running fine. My husband went to work and came home. About 10 minutes later he went out to leave and it wouldn't start. We left it sitting for a day and it started and ran fine. Then, it died down the road about 15 minutes later. Does that mean the relay is working?

The fuel pump sending unit assembly is 'way easier to deal with-sometimes getting the units apart to replace just the pump is a major pain. Need to actually see what the fuel pressure is(or isn't) when it won't start/run. By the way, MOST GM cars and trucks use a circuit in the oil pressure switch/sending unit to keep power to the pump even if the relay quits working. How do you know if that's the case? Extended cold start cranking times(the oil pressure has to build up before the pump is kicked on, rather than being fired up immediately by the relay.)

Before you change anything I'd do a fuel pressure test. As far as a shop replacing the pump you'd be looking at around 250 for just the pump and ranging up to 800 dollars for the complete unit, that's parts and labor. I prefer getting the whole assembly if you can afford it, that way if you have a fuel level issue later down the road, the sending unit would have been changed with the pump as a unit. I would also not use auto zone fuel pumps, go with delco.

Do a fuel pressure test after making sure the fuse and relay are OK. You can't just guess. I take it you have spark? Have someone tap on the gas tank with a 2x4 while you crank the motor over for a couple of tries to see if a stuck pump tries to work. It's not a fool proof way to diagnose a car, but it sometimes works in a pinch if you're lucky.

the only repair kits i have seen are usually a new pump motor and it is just a little extra work to swap it out of the sending unit you would be fine getting the kit as new as your car is.

If it is the fuel pump, probably hundreds of dollars.
