Where is the ignition module - I need the wiring diagrams as well?

I hate to ask, but because of the year, I can't remember. Does the engine have a crank sensor?

No it does not have a crank position sensor. The fuel control computer gets it s info off of the PIP output from the ignition control module.

1986 Ford Ranger 140,000 2.9 V6 Truck was running ok when parked but when tried to start we found that we had no spark. Engine turns over fine. Replaced the ignition module and the coil but still nothing.
Looking for ideas. Thanks

The coil feeds the distributor. Is there a good spark at the distributor?

Try replacing the pick up coil.

I am not getting any spark from the coil except for a very weak yellow spark when using jumper cables at which time I also get a very weak spark from the plug wires. With only the battery cranking (new bat.) I get nothing.

Is the "pick up coil" the same as the "stator" on this unit?

No, it's not the same as the starter. If you go to the auto parts store, they should know what you're talking about. I'm just assuming they will, because the stores around here hire a bunch of idiots.

Replaced the pick up coil today and everything is working fine now. It is the same as what the chilton manual refers to as the stator assy.
Thanks so much for the help

Glad I could help.

Engine Mechanical problem
1983 Ford Ranger 4 cyl Four Wheel Drive Manual

my ranger just all of a sudden started running real bad i have a 2.3 sohc with 2 barrel holley 5200 carb it started sputering and loosing power and iwould down shift and try to give it gas and it would choke down and backfire the the engine would quit wait a few minutes and it would eventually restart but wouldnt go far and do it again i have replaced the coil,ignition control module, plugs,and wires what else could be making it do this

It could be anything. It could be contaminated fuel. It could be a carbon track inside the distributor cap. Have you tried looking at the engine in total darkness to see if there is any arcing going on anywhere on the engine? It could even be corroded battery cables causing the engine to quit after accereration, and then restart after the engine stops.
