Weird problem! Starts, shuts off, repeat
Ok so last year we replaced the fuel pump; check, worked good.
Now, the truck dies after it's initially started.
The pump DOESNT whir like it use too, but I don't understand how it'll start (I did it four times in a row) and THEN shuts off.
When the pump would go out before, it wouldnt start at all. Now the engine turns over, but it stalls out within 2 seconds.
I switched around all my relays, and replaced 3 fuses in the side of the dash, the fuel related ones (cant recall the technical term).
I pulled the pump and everything LOOKS good, which I know doesn't mean much, but nothing looks faulty and it's not even a year old. The tank is full, as shown by the gauge that decided to work (didn't work before I put the pump back in and replaced a fuse, must have been the floater got stuck).
So to sum it up, I need advice on this...
Why would an engine start, then stall out, REPEATEDLY, within 2 seconds if the pump doesn't whir but the relay is good?
