I have a 88 4.3 EFI that will not start.. Lots of spark..
I think it is the Fuel Pump but am not sure..
anyone know whare the fuel pump relay is or have any sugestions???
I NEED HELP!!!!

Sorry for the spelling, my hands are freezing....LOL

Fuel pump relay is right up under the hood. Could be several things besides the pump. Checking for a good ground of the relay is important. I had same problem on my 89 5.7L. There was a ground located on the passenger side fenderwell. Several things were grounded there and it had worked loose. Also, there should be and oil pressure switch that will stop spark and fuel if not enough oil pressure is present. But since you say you have spark I don't think that's an issue.
