help with fi on 5.0 in a factory five mkll
fired up car 2 days ago and it ran fine. moved car to shop to work on it. next day went to fire it up and it would run but acted like it was starving for fuel. once it warmed up it seemed ok. today it would try to start for a second but wouldnt catch. I removed air cleaner and used some starting fluid. it fired up but still acted like it was starving for fuel. you could run the throttle up slowly and get some rpms ok, but if you stabbed the throttle it wouldn't gain any and almost stall. I know its a fuel problem and before I yank the tank and put a new fuel pump in are there any tests I could do? New to FI motors. eveything I have owned before was old and had a carb on it. Thnaks in advance and looking forward to some 3rd saturday breakfasts. car did sit for quite a while. fired it up occasionaly, but that was about it. put in fresh gas and fi cleaner.
