1991 Ford Explorer 6 cyl Four Wheel Drive Automatic 161000 miles
I have the following error codes when testing with the engine off: 16, 21, 24. I have replaced the crankshaft pickup sensor, engine coolant temp sensor, intake air sensor, engine coolant gauge sensor, engine ignition module, have 70 psi fuel pressure cranking. Checked spark at every cylinder, new spark plug wires. The engine backfires when it attemps to start. This engine was getting harder and harder to start when it wasn't started everyday. Now it will not start. I am starting to give up on it. It you have any help I would like to hear from you.
have the same problem?
