Thanks for the info pawpaw. I tried what you suggested. Grounded to the frrame and engine and even put a new relay in for the PCM and still no spark. I went and got an OBD II reader and it will not read. It keeps saying to check connection. The connection is good. No bent pins or broken wires. Could that mean that the PCM has gone bad? By the way everthing else works fine ie. lights, fan blower, fuel pump, ect just no spark to the plugs.
