Hi, I have a 1988 Delta 88 with a 3800 v6. I'm not getting any spark on the number one and 4 cylinders. I've replaced the crank sensor, cam position sensor, coil pack and the module underneath of it. Today I replaced the ECM, still no spark on the same 2 cylinders. I've checked for spark at the coil pack so I know it's not plugs or wires. I'm hoping someone here can give me a new idea to solve this problem. I would greatly appreciate a push in the right direction. Thanks very much.
