hi

i have a duel fuel setup in the rangie and it runns good on gas but nothing on fuel. a friend said the timing could be out but im thinking the injectors have been run on gas they seize up when fluid runs through them. i was looking at second hand injectors or a new set otherwise for now just going through the fuel system and eliminate any issues from the tank to the engine.

it pumps fine as it gets fuel and it will run but misses badly like its running on 3-4 cylinders only.

its a 3.9i engine out of a 89 model
