Replaced head gaskets (everything else was fine) took timing chains off and put engine back together. Now it won't start,everything is plugged in.i turn the key and engine won't run unless I have foot on gas.when I take foot of gas it dies!. Been told timing could be off. Been getting P0353-P0357. Truck ran fine besides the bad head gaskets. Any help if appriciated. Thanks. 2000 Durango 4.7 4x4

 

I'm not one to quit,so I wanna get this thing running.

 

have you read this thread?

we need more information at a minimum what year and engine do you have in the vehicle? once we have that information we can give you solid suggestiong instead of throwing **** at the wall to see if it sticks.

i would start by checking the connections on the coil packs, you had them off the truck to do the head gaskets so the easy stuff first.

You could also have a broken wire in the coil circuits, i would look for a common point in the wire harness and go from there (probably the power source since the PCM triggers the coils through ground)

3 and 7 are drivers side coils, 2nd and 4th from the front
