Hey Guys,
I just bought an 88 ranger last week it is 2wd 2.3ltr. It was running great, yesterday I changed the oil, when I started it afterwards it ran for about 1 minute and stopped. Fuel pump is working, I checked at the coil and have no spark. This morning I replaced the coil and wires... Still no spark... I talked to a mechanic friend of mine and he said it sounds the the control is gone and told me to hook a test light to the leads on the coil and one should be lit constant and the other off and on.. Did that red side was solid but nothing on the green. So I changed the control module... STILL NO SPARK!!! So far today I have about 5 hours and $60 worth of parts and no results... Also still nothing on the green wire going to the coil.. Also disconnected the battery to try and reset the computer and that didn't do anything either Any suggestions or ideas? This truck is driving me crazy....
Thanks,
Kevin

 

First, welcome to FTE!!!!

It sounds like you have a bad coil. Without the engine turning over, you should have 12V on both coil terminals.

 

Well it's running.. I decided to disconnect both battery terminals and let it sit for a while. Tried it about an hour later and it started right up.... I'm hoping it was just the computer needed rebooting... Thanks for all the help!

I'm having the same problem with my 86 ranger, you think the same thing would work with mine?

 

Hey fellas. I really need your help here. My truck has been sitting for entirely too long. Even for a FORD ! I haven't been able to start it for a month now. I can't get a spark from the ignition coils to the plug wires.

It's an 89 Ranger 2.3L EEC-VI DistributorLESS Ignition System. Dual coil packs are both new and working properly. New control module. Fuel pump works perfectly. Have done numerous testing of relays and for shorts. I have extracted the engine codes: 15 and 212

15 is EEC processor ROM test failed.
212 is Loss of Ignition Diagnostic Monitor (IDM) input to ECA/SPOUT circuit grounded

I am not quite positive about the 212 code.
Using my Analog meter the sweeps were in this pattern: II II I II II Am i reading the code wrong?

As I turn the key the starter cranks the engine, but no spark! I know that the Cranksaft position sensor works fine.

The whole senario started when the secondary igition coil was not firing while the engine was running. I replaced the coil. no change. Then i removed the DIS module to have it tested. It passed the test and i put it back on. I have never been able to start the truck since.

I am using the basic Haynes manual which has been usful to a point. But now i think i need some experiential help.

What are the codes REALLY pointing to ? Do i need a new Electronic Control Assembly?? I would appreciate any well thought out guidence to help fix this truck and get it back on the road.

Thanks, Xoryx
