My fuel pump keeps running before starting. It should cut off with in two or thee seconds and then stop until the engine starts. However, when I turn the key to the run position, the fuel pump keeps running and the engine will not start. If the pump stops the engine will start.
I am trouble shooting the electronic system to find the problem, and started with the crank shaft sensor. So, here is my questions:
The book says there should be 1.5 volt on one of the wires on the two contact which plug into the sensor. But, I tested these and there is 1.5 volts on both leads. I cant see how that would be normal.
I also checked the sensor with a volt meter and did get an slight pulse when my wife cranked over the engine. So, I assume that the sensor is ok. But, not getting a strong pulse, but several pulses of different strengths on the meter, not sure about that either.
I would appreciate any help please. Lead me in the right direction.
Also, I cleaned all the connectors with alcohol.
Thanks,
