1994 Ford Ranger • 130,000 miles
I have a 1994 ford ranger six cylinder 4 x 4 truck, runs rough. Strong fuel odor in exhaust. Have multiple trouble codes including 513, 556 and 565. Code 513 indicates an internal pcm voltage failure. Would this failure result in code 556 and 565? Should my first effort be to replace the pcm?
Before replacing the pcm, make sure that all fuses are good. Test them all with a test light to verify power.
Thanks Roy, but we check all the fuses and they all looked good, any other ideas?
Sorry, look good is not good enough. You need to check for power, thats why I reccomended using a test light
Checked all the fuses WITH a test light they are all fine. LOL What would be the next step to take?
Sounds like you will need to replace the pcm. It may fix all your issues but you need to start there.
