Does an 88 grand wagoneer have a diagnostic port? Vehicle will not turn over (no spark). We replaced coil and wires and still nothing. Any advice? Thank you
Did you replace the Ignition Control Module ? Take part with you to parts store they should be able to test it to make sure it is bad.
Ok thank you. Will do that. Do you know if there is a diagnostic port?
