I have a 1994 F150 4wd. It will not start. I have replaced the ignition module, coil, and pick-up assembly in the distributor. Still no fire coming from coil. I do have 12 volts going into the coil. Can anyone help an old farm boy from Kentucky?

 

Have you checked the Cap and rotor? Sometimes if there is gunk or rust in there you won't get any spark. But based on what you have replace there should be no reason that you wouldn't have spark.

 

Could be a problem with any of the new parts, if any were bad out-of-the-box. There are some pretty simple resistance tests that can be done with a multimeter - most shop manuals have the specs for your particular model.

IIRC, the spark is generated not by dropping the 12v out, but by opening the (-) side of the coil.

Good luck, welcome to the site, and keep us posted!

 

Check the power wire at the ICM, which is the red/green wire. Also check the computer for codes.

 

Same problem here. 94 2wd not starting. Fuel gauge went way over the top. This old 300 has never given me any troubles before. Checked the coil and cap & rotor already. Could the fuel sending unit be acting up?

 

Eh, can't think of how the fuel sending unit would affect starting.

My fuel gauge has read well in excess of Full for many years. It pretty much stays there until about 10 gallons have been burned off, then drops to 1/4 tank within 20 miles, then is pretty good from there on out until the tank is Empty, with the gauge needle one bump above 'E'.

Not the greatest system, but too lazy to drop the tank / pull the bed - just fill up about every 150 miles or so.

Suggest your first opportunity is to determine whether you have a fuel delivery or a spark problem.

 

How about a vacuum formed by a leak. I filled it Monday just before I parked it. Maybe it can't pump because of reverse pressure.

 

Have you resolved this issue? Could be the ground due to a bad battery connection or a bad ground cable. What kind of engine is it? The inline six engine routes the exhaust near the ground connection and this corrodes over time. Replacing the cable may help.

 

Normally I'd say replace the ignition module...
