Hi,
I've been cruising the forums and reading some articles and have a rough idea about ignition timing, crank position sensor etc. but I'm hoping someone more knowledgeable can help me out. I'll try to lay this out clearly.
I bought a OBD1 code reader. It pretty much told me every sensor was bad and after some reading and testing I determined the PCM itself was the problem. Went to NAPA bought a new PCM and viola! everything works. KOEO tests says no faults - yay!
Next test: Key On Engine Running. The manual for the code reader says, though, to be sure the ignition timing is set correctly or the KEOR test will give false readings. Ok... I go and look at the factory service manual and it just references another manual (emissions controls) for distributor ignition system.
Now the questions:
My 1994 2.3L Ranger Splash (with federal emissions) has an electronically controlled ignition system, the DIS - right? It's not adjustable, but it could fail. If it did fail - the truck would probably not even start. Is all that correct?
Does my 2.3L have a crankshaft position sensor and/or a camshaft position sensor? Would these affect the timing, and if they failed would the truck run? If it would run what symptoms would tip me off they were not working?
Lastly, is it basically safe to assume the ignition timing on my Ranger is good?
Thanks for any help. Little by little it's getting there.
