I am going by the '99-'06 Full size truck Chilton's Manual. The firing order should be the same. It is 1-6-5-4-3-2 on the v-6 engine. 1,3,5 are on the driver's side from grill to firewall and 2,4,6, are on the passenger's side from grill to firewall(this is in the heads). From the boot coming off the main coil(the only one not going to a spark plug) clockwise the firing order on the distributor is 5-1-3-2-4-6. Also make sure the plugs are gapped at .060 in. Hope this helps.

Changed spark plugs and wires on 98 dodge ram. Now it backfires and has no power


Make sure that the firing order was not changed when you took the spark plug wires off of the plugs. You might also want to double check the gap on the plug. Let me know if neither of these were it.
