Question: I have an 88 gt v6 automatic. the car many times takes 6-7 cranks to start. Occasionally it starts in one to two cranks. The car has been tuned up and fuel pump has been checked for presure - all okay. What could it be?
Answer: Does the car have a 2 second run of the fuel pump when key is turned on. If not, fuel pump relay is probably not working, and fuel pump is not turned on until after the engine is cranked over, at which time the oil pressure sender will activate it.
If you have the 2 second run, then it sounds as though the fuel system has lost pressure. This is usually due to a "leaky" injector.
