Hi Sheila, i'm glad to help. 99 Durango's with thew 5.2 liter engine were good about the Crank Sensors going bad. Now, as I can't say that securily with out diagnosis. If it were my vehicle and knowing what I know about no starts, that is diffinently where I would start. Hope this helps and have an awesome day Sheila.
Try the tps, throttle position sensor, and the idacv, idle air control valve. Even sometimes the temp sensor could be bad, telling the motor its cold when its really hot..
I remember my wife's old Lumina had the head gasket replaced and hearing about the TSB (technical service bulliten) on the engine. Check your engine oil and coolant.....if the oil looks milky (whitish brown) or the coolant looks like it has oil in it, you may have seroius engine damage. If the oil and coolant looks ok, get a few estimates on replacing the intake gasket, but don't gamble that it will resolve you issue.
If the cost of the repairs are more than half the value of the car, it's time to let it go...
