Fuel Problem I have an 88 ford ranger ext. cab.,4x4 2.9 liter with a standard tanny. My problem is is that I have right psi at injector rail, and power to injectors but fuel isn't going through the injectors to the engine. Replaced injectors, Throttle Position Sensor, computer, fuel pump relay among other things, but truck still won't start. Spray starting fluid into dome starts in 1 crank. Any clue?

I have checked fuel pressure and it is at 40 psi when the engine off and the key turned to the on position. I have checked fuel pressure and it is at 40 psi when the engine off and the key turned to the on position.

have you checked out the mas air sensor? is the check engine light on and have you had it hooked up to a computer and have any trouble codes come up. if you take it to autozone they check the computor for free
