Default 90 ranger 4cyl auto, starts and runs but have to hold key..

Hi guys,

I have a 90 Ford Ranger 4 cyl auto that has problems staying running. I can crank it and it will start like normal, but when i start to ease the key back into the run position it will die. From the off position i can turn the key and the CEL will come on and the battery light is on too but if i turn it just a hair more the CEL goes off but the battery light is still on.

-fuses in the engine bay all good
-didnt check fuses by the driver side footwell cause i thought they were all auxilary, plus i lost the cover/legend
-replaced ignition key cylinder, no change
-did not check alternator or battery with multimeter yet but i will once i find out where i put it last
-faulty modules? dont know which one(s) could be affecting it, i wouldnt even know where to find them unless i saw a diagram.
-possible bad ground/wiring connection somewhere?

Its like there is a tiny dead zone somewhere close to where the key is in the run position. Because i've managed to start the car move the key backwards and found the dead zone, but if i'm fast enough i can go past the dead zone and stop short of the OFF position to keep the car running.

I would check the ignition module normally located on the distributor.

Also check the ignition switch which is located int the steering column

To use a test light:

Turn the ignition key off and disconnect the wire connector at the module.
Disconnect the S terminal of the starter solenoid to prevent the engine from cranking when the ignition is in the run position.
Turn the key to the run position and probe the red wire connection to check for voltage.
Check for voltage at the battery terminal of the ignition coil using the test light.
Next, turn the key to the start position and check for voltage at the white wire connector at the module and the battery terminal of the ignition coil. If voltage is present, the switch and its circuit are okay.

I dont have a test light just an actron multimeter, can the test be done with that? i havent done any car work in over 2 years so i'm a bit rusty, but it sounds like i'm just doing a continuity test, is that correct?

I never used a meter to test one. Test lights are like 5 bucks at walmart
