Ignition problem (need help)
I have a 1994 F150 5.0
Problem is no spark, code 212. So far I have replaced the distributor, cap, rotor, wires, ICM (twice one black one gray) o2 Sensor, thermostat and EGR valve. Looked for broken or shorted wires, tested the coil and cleaned all the connectors. The problem was intermitent but now it won't start at all. qThe proplem seamed to start after a major somke condition comming out of the dash (smelled like burning leaves) not sure it had any connection though. It also seamed to be worse on hot sunny days. I am going back to step one in the Haynes manual and this is my first question. The Section "Module and coil (START) supply voltage" says to insert pins into the red and white module wires, I can't locate these wires??? is it the pcm module the tfi or what? any suggestions would be greatly appreciated.
Thanks
Tom
