Cali56,

Seeing how absolutely NO diagnosis (apart from changing parts without seeing if they work) seems to have been done, therefore no reading of any technical manuals, there's not much point describing why disconnecting one injector might get the motor to start.

If you read my post it said "check the fuel pressure" as the engine possibly has fuel pressure regulator failure.. which is very common in running rich problems. You might also notice that, according to the posts, it hasn't been done yet.

Removing the injector wire leans off the system enough it may run by reducing the total amount of fuel available, but the air amount remains the same. And yes, I do know it is then only a three cylinder motor.
I've done this in car park before when diagnosing non-starts without tools. You can also loosen off the air intake hose to allow more air..on the engine side of the throttle body. It should allow the engine to at least run.. which sort of moves one to the postion of knowing what the fault is rather than guessing.
Most times with fuel presure problems result in the engine cranking, running and then stopping..when cold. At normal operating temperatures it won't start at all because the fuel/air ratio is way too rich.

It all comes back to diagnosis in a logical path. Not doing that takes way longer and tends to be expensive.


Ok, ok where did that cali56 post go?
