Thank you Alan. So the [engine](/topics-engine-chevy/) currently cranks but does not start? Do you hear the fuel pump running while cranking?

Correct. I'm by myself, and not sure if it is working. My buzzer is too loud

Sounds good. Thank you for that information. Basically you need to check for spark and fuel while cranking the engine over. It may be easier to do this with an assistant. If it has spark it should start and run and starting fluid. If it does then you have to check fuel pressure while cranking. If there is no fuel pressure but the fuel pump has been replaced, it may not be receiving power for reason. At that point you would need to check for power going to the fuel pump using a voltmeter and check the entire fuel pump circuit to determine where it's missing or losing voltage. If there's no spark while cranking you need to check the ignition system. You can start by getting yourself a scan tool and reading engine RPM on your live data while cranking it over.

Ok. I'll give that a try

Sounds good, you are most welcome! It has been a pleasure working with you so far. Keep in mind this is a “starting point”. We can always continue as needed at a later date or at any time. Feel free to run some tests and reply back for further assistance as needed. Glad I can help. Please let me know if you have any further questions. Thanks and have a great day!

Ok. Thanks

You are most welcome!

It just started. What would make it all the sudden start? It runs fine when it starts.

It could be anything electrical. Sensor, switch, connection etc..

Ok. I'll check that stuff. Thanks for your time

You need to check for spark and fuel when this occurs to determine what’s going on. Keep in mind you can reply back to me on this page and I’ll be happy to continue to assist you once I know if the engine is missing spark or fuel we can continue then
