spark on 1 and 4 but not 2 and 3

[DiamondStar90]

what controls spark on 2 and 3 as i have no spark and i tried another coil packa nd still no difference?

well take a multimeter do a continuity check on the wires for cylinders 2 and 3 to check if the wires are bad, and check the spark plugs.

The first suspect would be your power transistor. Ask a buddy with a DSM to swap with you and report back. Otherwise you are going to have to troubleshoot with a meter. If you dont know how, now is a good time to learn.
