I had the same exact problem with my 1998 Explorer and it was the Idle Air Control. You can try to remove and clean it but it won't last very long. I replaced it myself in 5 minutes and an expense of $80. Hope this helps.

SOURCE: 1990 gmc 6500 topkick with no spark or injector pulse

You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.

1984 f250 fires only when rolling back key switch

If your saying no spark at the plugs, The positive side of ignition coil should be hot, with key in crank or run position. If it isn't, I'd have to check ignition switch and wiring circuits.
I don't have a good wiring diagram for your model year, I can't look up wiring.

83 ford e350 starts to the start position and then dies in the run position need help

Sounds like you have a wiring problem, check the plug connector and wiring that plugs into the ignition switch, look for discoloration or signs of over heating or melting, if ok , unplug the connector from the ignition switch and with 2 jumper wires you can hot wire you car, and test if it stays running, jump the hot wire to the coil wire, and jump the hot wire from the starter to ground until it starts up.

1970 truck. How do I start it without a key?

It should be easy to hot-wire the switch. There is a hot power-in wire, a run wire at the "on" position, and a start wire at the start position. That is all you need. First locate the power wire, twist it with the run wire. Now the ignition should be on, the dash warning lights and gauges on. Now if you take the start wire and touch it to those two twisted together, the engine should crank over and start.

This is a quick way to get it started, but you have to cut the wires. If you pull off the ignition switch connector, you might be able to use short jumper wires from the hot wire to the run position, and one to the start wire. Then if you get a new key and lock cylinder later, all you have to do is to plug back in the switch connector.

Starting issue, I have a 1993 ford f250 7.3l pre powerstroke. I started the motor and it stalled out like there was a short, now when i turn the key my glow plugs do not fire and wait to start doesnt show...

On some Models the glow plug Relay does not have an integrated Power Relay. This means there is a second Relay before the glow plug Relay that feeds it power.

You should check the wires running to the glow plug Relay for power with the key ON. Check some other wires off of the Ignition switch to make sure your 20 year old Ignition switch is good.

There are some sites which show vehicle wiring. Autozone has a free section after Registering your vehicle but it takes a little sorting through the Help section. There should be a fuse to protect the above Relays.

Make sure you find the Diesel-equipped wiring circuit. Diesel ignitions are different from gas units.

I got a 89 dodge d 150 v6 no fire at the coil can run a hot wire to the coil and it runs what does this regulator look like and where is it located

Try this jumper the ballast resistor on the fire wall if you have one looks like a block of white ceramic wit two or four wires. Jump them across not up and down If you check voltage on the right side 12 volt left side lower to protect coil from 12 volts. If that doesn't work your shut down relay may be bad. If not getting voltage to resister could be the starter switch on top of steering column under dash. Key switch is not ignition switch. The key switch pulls a lever up on the ignition switch if switch is not set right it will not send power to the coil. I had two break before on me. The book says to follow the wire all the way back to the battery and look for breaks

96 ford explorer wont start. all power when turn key. nothing.

if it turns over from below,then its in the ignition switch and this also feeds power to the e.c.m. to make the engine fire so you either have a bad switch contact or the hot 12 volt wire to the ignition switch

My 1989 ecoline 150 starter fires when u connect the batteryreplaced starter solinoid and ignition switch and keyswitch still starts no key and will still run after van starts

look for shorted wires leading from your starter solenoid to your ignition switch.
the wires are shorted "on" before they get to your ignition switch.
separate the burned/shorted wires: (most likely under the dash) then tape them so they don't touch.
