Are you saying that the engine cranks over but does not start or are you saying that it does not crank over at all?

Are there any codes in the computer?

The engine cranks, but almost sounds like a fuel systems lean. However, the fuel pump was replaced around September, no error codes and no check engine light. The fuel rail also is getting a good 60psi.
Expert:  Amedee replied 3 months ago.

Thank you for that information.

So the engine cranks over but does not start a times correct?

It has 60 psi of fuel pressure when this no start condition occurs?

Have you checked for spark when this happens?

Customer: replied 3 months ago.
Correct, as I explained to the agent, I have to jack up the front just to get a better chance of starting. Most turns needed jacked up is 3 key turns, I'm lucky to get it within 6 key turns on level ground. It gets 60psi once it fully cranks and runs, and a mechanic told me a bad spark plug wouldn't prevent a start.
Customer: replied 3 months ago.
just recently, I spent almost $180 for a starter and I'm still having same issue as I did with old starter.
Expert:  Amedee replied 3 months ago.

If the engine is cranking over and not starting, it has nothing to do with the starter motor.

Please check for spark when this condition occurs and reply back so we can continue.

Customer: replied 3 months ago.
Ok,and how would I do that in a short amount of time? I've gotta be at work in an hour
Expert:  Amedee replied 3 months ago.

You will have to wait until the problem act up again.

Once it does, you will need to have a spark tester ready/available and install it going to one of the spark plugs and watch for spark as an assistant cranks the engine over.

No hurry on my end. Simply reply back when you have this information.

Customer: replied 3 months ago.
Ok, I hope my mechanic has such a tool. I'm not going to be able to buy my own as of now, starter put me in a bind and hoping I can return it to autozone.
Expert:  Amedee replied 3 months ago.

I hear ya!

The spark tester should be less than 10 bucks.

I will be looking forward to your reply.

Youtube video of something similar my Jeep has been doing: https://youtu.be/v5dM5--ZXHs this is not my video or vehicle, just similar symptoms. If it takes 1 key turn, sometimes sounds exactly the same.
Expert:  Amedee replied 3 months ago.

Got it!

So the engine cranks and cranks for some time before it starts..

Customer: replied 3 months ago.
Expert:  Amedee replied 3 months ago.

Thank you. I understand now what is going on.

Customer: replied 3 months ago.
Ok, so what does it sound like and what is your opinion?
Expert:  Amedee replied 3 months ago.

Its too early to tell.

Testing needs to be done

Customer: replied 3 months ago.
Ok, I'll see what I can do
Expert:  Amedee replied 3 months ago.

Sounds good
