I have a 1989 Ford Bronco, I have replaced the key Cylinder, Ignition Switch, and even the pigtail Harness that attaches to the ignition switch. and my truck still will not turn over, what else could it be? or what am I doing wrong?

Do you have power to the ignition switch if so and the starter motor is not engaging the engine-Check the starter motor, starter relay and transmission range switch. Here is the ignition. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed. switch wiring.

can you run a 12 volt jumper wire from the battery to the "s" terminal of the solenoid. only touch it momentarily. if it works, you have bypassed the "start position" of your ignition switch

this will result in the solenoid operating and engaging the starter

watch out for those pesky moving engine parts, the sudden engagement of the starter will scare the mcdookey out of you!

you will jump!just stay away from those pesky moving parts!

if the starter does work, you have eliminated the solenoid and starter from the equation

to eliminate the dummy part, insure the "s" terminal had the correct wire on it----the one generating 12 volts w/ key in the start position. if there is another wire mistakenly on it, it probably belongs to "i" terminal. and they are backwards!

give your results from this and we may be able to diagnose better

Good deal!

Now we know that "S" wire is not getting 12 Volts, when the key is in the "Start Position"

I just happened by....thought I might "RAZ" the "RAZ"!!!!!!

Thanks for replying, I'll stay up for you, a bit longer, it's 0130 Eastern here!

Were you CONFIDENT in installing your ignition switch? Did you run it thru the motions, or were you sorta "cherry", doing one for the 1st time?

Just trying to keep this interesting, to keep me awake!

I know you must be really upset right now......I will do my best to help.

I do have some homemade pics of another Ford's switch.......I can talk you thru it, if there is the slightest possibility.......that you think you installed/ calibrated it wrong.

I hope my pics are similar enough to yours

Your turn

All-Righty Then

Fast and furious

The "Nelsomatic" way of installing a Jeep CJ ignition switch/ Ford ignition switch!

I can do this without dropping the column, the only reason I dropped it on this F-100 was to get these pics

Usually someone never having done one before, installs it right, fights the "L" shaped rod forever, but just don't get it adjusted right! Usually they have the lock cylinder turning way too much clockwise, and "Start" never gets engaged!

The EZist way I have found is to "Preset" the ignition switch for the "Accessories Position"----Then turn the key to the accessories position.

Install the switch, and rod together, Being ever so careful not to move the ignition switch from the accessories position, and keeping the key rotated, all the way Counter-Clockwise

Screw it in place

Then try all of the positions

Sometimes, you may have to loosen the screws and tweak the switch, forward or rearward, just a little bit-----But rarely, do I have to.

I always use dielectric grease on my electrical connections before I reconnect it.

That work?

I'll help you later in the morn, if you still need assistance, if Raz ain't got you fixed by then.

Bedtime Raz

You're on "Fire Guard"

OK It will crank when I bypass it, so I take it I did not adjust the ignition switch correctly. I also found a bad wire I didn't notice before so I tore everything back apart to fix it. but if i need help i will be knocking on your door! thanks again

ok I got it started and it was running, but I moved onto the next project of putting a new transmission in. I got the new one but it was an upgrade to a stage 1. I put it in, and got everything hooked back where it was supposed to be. but now when I go to start it I only get a loud clank. I removed the starter and tested it, battery is good, new starter solenoid. what can this be?

Same flywheel as before?

Same tooth count, same diameter?

Can you rotate (in the direction the engine normally turns) the engine with a "Pull Handle" and a socket on the crankshaft pulley nut?.....Ain't locked down... is it?

I doubt it! When torqued, even too much, the pieces will face together...far as they will go!

Something is in a bind!

Or you have the wrong application!

In neutral....transmission and transfer case...any combination of the 2, can you turn the Rear out put or the front output shafts on the transfer case?

What I mean is can you make the tranny innards move, by turning the transfer case yokes?

Just trying to figure out which is the problem....could the transfer case be between functions?

The more I ponder.......I also wonder if your torque converter is "Crammed"/ "Jammed" in between the tranny and the engine?

You really shoulda got a CJ!

We woulda had you fixed long ago!

Did you do any precise measuring of Old VS: New?

I took my starter off and is finding wear on it. right behind the spindle on it. The transfer case is in the normal operations so is not part of the problem. but I think I'M going to try to shim the starter and see if that works. I'll keep you posted,

If you really meant that you could not turn the engine over by hand (with starter removed, in case it was hung up in the teeth, WAS IT?) How do you expect the starter to move it?

What I think I need to do is shim the starter! the teeth are not touching at all and the teeth on the starter are going part the fly wheel.

"and the teeth on the starter are going part the fly wheel"?????

I translate the above statement to mean, "I wish I had a CJ, This Bronco has my speech and thinking impaired....I wanna be like CJ MEDEVAC"

Maybe I'm not understanding stuff?

Usually Shimming a starter, means "spacing it further from the flywheel"

On Fords that would be mean spacing the starter toward the front bumper "lessening throw of the starter drive"

On Chevrolets, shimming would be downward, moving the teeth of the starter, out of the flywheel teeth...Kinda like moving it out of "Orbit", further from the center-line axis.....shimming a Chevy, usually means the teeth were crammed together and binding, and needed more space between them

Like I said, I ain't there, and I ain't understanding 'zackly what you got goin' on

But I am still here, if you need me!

Keep me posted
