what car?

The manual for my integra says fuse 24 is for the fuel pump. It goes through the main relay too so check that.

or prelude. You can just pull the main relay out, and solder the points when u pull it out of the plastic case. I soldered mine and it was obvious that some of the points had cracks in them from getting hot. My ---- used to stall at lights, and wouldn't start for about 10 minutes.

If u have a multimeter, check power going to the pump when you turn the key to the ON position.

My vote is main relay.....BTW they're all the same for obd1 honda's

I say DL the service manual for ur car.

Are you sure ur getting spark....u said u think u are.
Pull out a plug and put it in a wire and watch while trying to start the car.

Is there gas in ur tank?

well, maybe your pump is out. more info, what did you do before this started happening.

did it happen all at once or did it intermittently start to go out.
