    Which engine is this? If a 4.0L is it the SOHC or OHV engine?

    Well, you know the drill - it's fuel, spark, air and exhaust.

    That engine is known for the o-ring intake gaskets to leak, and "pops" sounds like you might have an leak somewhere...that's one thing to look at. Fuel quality is something to look at -- did you drain and fill the tank with fresh fuel?

    What was the reason the car sat for a few years?

    I did not know about the o-rings I will check that but I am down to thinking stuck or sticking valves I squirted a good quality of carb cleaner while turning it over that should have ruled out the bad fuel .She said the transmision was bad it belonged to her sister and was given to her to fix if she wanted it I told her I would not do anything else to it until it is running and I got to check it all out .SOUNDS like I opened a bag of worms as we use to say ]]]]
    Thanks Johnny

    I honestly don't think stuck valves is your issue here.

    If you had good fuel pressure, why the carb cleaner to help start it? Just a thought.

    If it's sucking signficant air, a stone cold engine doesn't stand a chance. That's why I went with the leak.
