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

 

I would start by pulling the codes. Tech info post has the procedure.

 

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!
