It died!

[gordyn]

I have a 90 ranger with the 2.9, I had it running in the shop the other night and it died just as if the key had been shut off. It won't restart, it's getting fuel so it has to be a spark issue. Wiring is not my strong suite so I'm looking for help on what it might be. Thanks.

Howdy Gordyn, and welcome to TRS~!

I would suggest a simple test for the spark that only requires the help of someone or really good eyesight. Remove one of the plugs, and fasten it somehow to the top of the engine or hold it (if you have someone to help) so that the tip of the spark plug is almost touching the valve cover. Have your assistant crank the engine and watch the tip of the plug to see if it archs. Turning the lights out might help a bit.

If you have spark, check one of the other plug tips for fuel saturation...if not, the issue could be fuel supply anywhere from the rear pump in the tank (not usually) or the one on the rail under the driver side foot well.

I guess it might also help if you posted a bit more info such as how you tested for fuel...and did you test for fuel pressure...have you changed fuel filters or any other parts will also be of help to others who want to offer suggestions.

Simple test for spark. Take the coil wire off the distributor, put a phillips screwdriver in the end, and hold it near something metal. Have someone crank the engine, if you have spark you will know. DON'T TOUCH THE BODY!!! It won't kill you, but it will be.... unpleasant for a few minutes.

If you don't have spark replace the ignition module.

Thanks for the advice! It started, not sure why but it did. I went out to pull a plug and check the spark, I played with a couple of the connectors first and when I rolled it over it fired right up. It's been sitting for a couple years while I've been working on it, I think maybe it's time for some electrical contact cleaner and see what happens.
