okay heres the problem. i start my car it cranks just fine. i have spark and all that , but the damn fuel pump (walboro 255 lph) is coming on for like a half second then shutting right off. i replaced teh relay but its still doing it im stranded in ny on vacation and i have to be back at work by wednesday. anyone have any ideas. even maybe hardwiring it will that work. i even put my stock pump back in and it does the same thing so i know the pump is good, its just that it shiuts right off. the search said it was the relay so im out of ideas. PLEASE HEL . thanks in advance for any suggestions.

Take a multi meter and check the wiring to make sure you are not grounding out somewhere, make sure the pump is actually seeing voltage when the car is on.

Also check the ASD relay, when the ECU seeing something it doesn't like it trips this relay and kills fuel.

Don't suppose you have access to a datalogger while you are stranded.

Smooth idle? We don't need no stinking smooth idle.

no i dont have a datalogger. whats a acd relay though ive never heard of that im kinda scared now.

ASD and fuel pump relays are the black boxes on the drivers side firewall, the fuel pump relay is the one closest to the engine
