I have a 1993 mustang 4 cylinder. It will crank if you prime the fuel pump which is new. It runs really ruff untill it warms up then it runs fine. Can anyone tell me why?
run 2 cans of ZMAX fuel cleaner in the gas ...change fuel filter and check startin/run pressures..
We have a new fuel filter and a new fuel pressure regulator. Also new plugs wires starter and two new cylinoide. Even spent $528 at the shop im at a loss
