I parked the car after work. Got up next morning wouldn't crank. Not turning over. Went bought a new battery and a starter relay. Will turn over like it trying to crank. Someone told me it could be the crankshaft senor, so I replaced it and the camshaft senor. Still no crank then replaced the MAP senor. I hear the fuel pump coming on. The car will turn over but will not crank. Please help

Hi,

When you have a crank no-start condition, it is usually either a fuel or ignition-related issue. Here is what I need you to do. See if the engine starts or tries to start when using starting fluid. If it does and then stalls, suspect it is a fuel-related issue. If there is no change, I need you to check for spark at the spark plugs.

Here is a link that explains how that is done:

Try this and let me know the results. Also, although you hear the fuel pump running, it may not be producing the fuel pressure needed to run the engine. This simple test will help point us in the right direction.

Let me know.

take care,

joe

We checked the plugs and there was no spark. We also tried the starting fluid and no crank. The computer is not pulling any codes. We checked all the fuses and relays. Is there anyway somehow that it might have jumped time? If so, how?

Hi,

Anything is possible. Is it possible for you to record it cranking and upload it for me to hear? I may be able to tell it is a timing-related issue.

Also, I need you to check for power to the ignition coils. If you look at the connectors, you'll notice that each coil will have a dark green wire with a light green tracer. (See pic below) That is the power supply to each coil. With the key on, that should have power. I need you to check to make sure there is power present.

Let me know.

Take care,

Joe
