please explain,,,,does the fuel pump come on for 2 seconds when you first turn the key on?
tell me how and when it started doing this?
do you have any codes in the computer?if so,please give me the codes
Here it is. No 2 sec blast. No pump. But, if the pump is by-passed at the fuel pump relay, it will run, although the engine won't engage. What if any, conditions must be met to satisfy the PCM to tell the Fuel Pump Relay to pick-up? and could that possibly be why that even though the pump has been by-passed, the vehicle won't fire.
At this point I'm not interested whether or not pressure is at the fuel rail. Why won't the PCM tell the Fuel Pump Relay to pick-up?
make sure you don't have any blown fuses.....but
sense it don't come on for the first 2 seconds,,i would think the computer itself is bad...the reason it wont run when you jump the relay..is because it don't have an injector pulse..the computer should always energize the relay when you first turn on the key
