Crank no start

Hi,

I'm getting confused. You indicated it didn't start with starting fluid.

Okay, the fuel pressure is perfect until you crank the engine. As far as fuel pressure, 35 to 40 is too low. However, I would expect it to start and then stall. Is that happening? Also, you indicated above that the ignition coils get power in the start position but not in the on position. Is that correct? If so, have you checked the relays I mentioned above?

Let me know.

Okay, I had you check the injectors for power, and you indicated there is. So, that should be fine. That leaves fuel pressure. You originally indicated you couldn't hear the fuel pump running, so the pump was replaced and the pressure is within the manufacturer's specs.

Here is the thing. We have spark, fuel, and compression. It starts with starting fluid, so we know it isn't a timing issue. Therefore, it should run, so we are missing something simple.

There is one last thing we can check and that is to confirm the fuel injectors are pulsing. They can have power, but if the PCM doesn't provide a ground path, they won't inject fuel.

You can use a test light or a noid light to check for this. Follow the directions in this link and let me know the results:

Hi,

Do me a favor. Record it cranking and upload it for me to hear. If you have spark, proper fuel pressure, the injectors are pulsing, and the compression is good, the engine should run.

Let me know.

Hi,

Thank you for the update. I appreciate and am glad to know it's running for you. I'm surprised you had spark if the crankshaft position sensor was bad, but anything is possible.

Please feel free to come back anytime in the future if you have questions or need help. You're always welcome here.

Take care,

Joe
