timeing or injectors?
 

it is popping and white smoke. its like a train and chugs. and when i floor it it pops louder than when just driving

check the timeing and then go with injectors

could the pump be going out? idk what the symptoms are for that. do you have to take it all apart the same as if you were setting the time to check it?

bad inj dirt in it after its warm losen the inj nut's 1 at a time the one that make the most diff is the dirty one remove entire line from pump to that inj DONT bend it out of hte way now remove that inj get a couple of box wrenches and take it apart carefully to note position of small pices clean all w carb clean or brake clean berkable 2+2 is worth the money to get inj out after removing line, soak w pb blaster worth the money, take wrench i think it was 12mm or1/2 dont rember place open end on the square flat to the side of where line goes in gently rotate just a hair left & right now with a lug nut yes a lug nut screwed on the threads pull upward w plier's and rock L & R with thw wrench pulling up n out . if you need more help email me you ph # and ill call you my email mikemopar@yahoo

Whats your fuel pressure.

white smoke and popping. I'm going to say timing. Check that first then worry about the injectors.
