I have a 91 ford ranger 4.0 4x4 distuberless truck and recently the truck has lost spark to the plugs u can turn it over and over and no spark there when I ground the plugs. I replaced the edis also replaced the crankshaft sensor and also replaced the coil pack. Ignition switch has been replaced. The computer and the ecc relay has been replaced. It fires up and sits there and running and it dies out of the blue like u shut off the key. When it is running its running fine. When it dies it has no spark at the spark plug again.I replaced all spark plug wires also. I bought a expesive code scanner and scaned it for codes and no codes are reading. What could be the problem?
have the same problem?
