Question about 2004 Pontiac Sunfire

Why is the fuel relay buzzing and car won't start? the dash lights are flickering on and off, and the relay buzzes for like 3-5 seconds, and the startes just keeps trying to turn over the engine. it started shutting off wehile driving one day, and the dash lkights started to flicker,a dn this happened a couple times over about a weeks worth of time, and then it hasn't started since. i was told to replace the starter, the fuel pump relay, and they are also suggesting the fuel pump be changed, but the line leading into the engine has fuel pressure in it...so i'm stuck,

I had a similar problem and though it was my alternator, it turned out it was the fuel pump, and you have to drop the fuel tank out to get to it, very expensive, but fixed the problem and runs fine now.

Sounds like originally your alternator is over charging causing dash lights to come on and flicker while driving then battery is flat(low) causing problem when starting
jump start engine, check alternator charge rate, and get battery recharged and then checked(load tested)

swap your fuel pump relay with something like your horn relay but the relay is almost never the problem to check the fuel pump turn the key on and listen near the filler cap if the fuel pump buzzes the fuel pump will only buzz for 3 to 5 seconds check for fuel pressure at the fuel rail it could also be fuel filter stopped up or pressure regulator

The way to approach this sreies of issues is to first remove the remote start/alarm from the equation and restore the vans electrical system back to original. From there, if it persists, we can do more trouble shooting. Let me know and I can walk you through the process. This is definately a problem that does require a diagnostician. Thank you for the level of detail you provided!

The buzzing sound under the could could come from an electrical component, particularly relays. There may be exposed wires or poor grounding which may have caused the relays to trigger and your car to work unusually. The relays normally found under the hood are the EFI relay. It could also be the idle compensator for the aircon that may have caused the sound which is still related to the electrical component of the car.

Where is the fuel pump relay on a 1998 Legacy Outback AWD wagon?


The fuel pump relay is located under the dash on the drivers side. If I remember correctly there are 3 relays next to each other and the fuel pump relay is the middle one.
