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.

Sounds like you will need to replace the pcm. It may fix all your issues but you need to start there.
