My problem started with my starter relay clicking after I have turned the engine off, lasted all of 5 seconds. So I buy a new stater relay, same thing, than it started to last longer, 10 - 20 seconds and my fuel pump would run at the same time the relay was ticking... So fuel pump would run with the relay, (same amount of time) when the relay stoped clicking the pump stoped. (Main Fuel Pump on the frame rail)
Than driving home my engine light comes on and the truck dies out. (In the snow storm we had last week!) I pull over turn it off, and it starts right back up, and runs fine. 15min later same thing happens. The truck starts to not run as long before the engine light comes on. The truck WOULD run wile the engine light was on, but VERY RUFF! Now I cant really get it started at all... It will start for maybe 5 seconds than just die right out. Any ideas what this may be?
Ive been told either Computer, key relay...
