Battling Electrical Problems


If the plugs are dry that sounds like the injectors arent firing.
 
Unfortunately am coming to that conclusion
The 2.9 is batch fire. Meaning it fires 3 at a time. The ECM grounds the injectors to fire them. If the injectors are getting 12v power, either the wires from the ECM to injectors are bad...or the ECM is bad. Since its all 6 id bet on the ECM

I’ve heard they go out all the time on these, is it really just plug in play or will need to program it. Any way to diagnose it’s the problem?
Thanks

I dont know how to test it. But yes they are plug and play....just get an 88 ECM. Only difference is manual or auto trans.
 
I manual swapped, stick with original auto or get the manual? I’m thinking just stay with it.
Manual. I went through that with my 4.0 swap, I had a manual and the only computer I could lay my hands on was an auto, so I ran with it for years. Finally decided to buy a manual computer and found two things… my auto computer was always a little funny and it also had bad capacitors at the end. The manual computer fixed a lot of things and made it run a lot better.
 
i should also add that california or federal emissions matter too

Very good to know, will be ordering one later this afternoon. I noticed I don’t get a single code when trying to read them. In the past I ALWAYS had at least egr. Now it doesn’t even show a test code.
 
Should be on the sticker near the hood latch. If that's not there (or readable),

Does your 88 have a Mass Air Flow sensor?
If yes then California Emissions.
If no the Federal Emissions.

88 wouldnt be MAF regardless. That didnt hit till 90 IIRC

@ty.forestcom best thing to do is just pull your ECM out (its easy) and get the numbers off it....or post a pic

Really? I didn't know that. So my Ranger is currently California compliant? Here's the sticker. It doesn't say anything about California. It just mentions US EPA reg's
