Why my 5.9L hdc v8 engin wont start.

What is your question?

I wrote the previous 2 question and now im adding to it. Now my truck wont even start at all. Before i had a problem with it stalling while driving and right before it would stall it would make a popping noise from the engine compartment. Then i would have to wait at least 15 min to start it again. Also it wouldnt stall as long as it was in park even when reving the engine it was fine. But as soon as it is put in gear it would stall. But now it doesnt want to start. Is this enough info to help get an answer.

What makes this problem better or worse?

Its would run fine until it got hot.

How long has your 1993 Dodge D350 had this problem?

A long time 6months or longer
