Hey guys, hope someone can help me. For the first time ever since owning it my crazy reliable Trooper is not running.
1990 Isuzu Trooper 2.6, Manual
Headed home late Saturday night. Felt Trooper kinda shudder, then check engine light flashed on and it stumbled then continued running normally again (never done anything like this always has run very very strong). Came to the next stop sign and suddenly it was sputtering and barely running. I managed to make it the few blocks home only able to run at about 15-20mph. It barely made it, this was all in first or second, gas pedal all the way to the floor. Engine also seemed to be lugging like I was in too high of a gear. Yesterday I checked the code and it threw a Code 44, lean condition. I feel like it was getting starved for fuel. Now I can start it and it will run for a second then sputter out and die. Will start every time and sounds good for literally a second or two then dies every time. First I thought my alternator went, it's a recently "new" Oreilly special... but I jumped the relay and it still won't run. Nothing changes with the relay jumped. Fuel pump is clearly running. I checked the fuel filter, which seemed very plugged up and changed it for a new one while I was down there. But problem still persists. I attached a fuel pressure gauge to the outlet line, but before the fuel pressure regulator because I could not get the line off after it. It reads 20 psi when I try to start the engine or jump the fuel pump relay. A steady 20 psi...
So fuel pump went out? Could it suddenly die like that but still be able to pump at half the psi? That is what seems strange to me. No symptoms prior. :?
Thanks in advance for any help!!!
