I have a 1990 v8 3.9 efi. All was fine until I lost cylinder 4 and 6. I took it to a mechanic and the top gasket was blown. Apparently it was due to irregular firing from the distributor. I've had the engine redone and have recently found a new distributor. The problem is that it now does not fire at all. the distributor that was originally in the motor had an amplifier that plugged directly onto the distributor and the new distributor has two wires coming out to a plug that has another two wires coming out. We have plugged the amplifier on to the system, but there is no fire at all. the new dissy is a 35dm8. I don't know what we are missing. for some reason there is no spark from the coil.
