OK, I replaced those ignition parts in my '89 F250

CalusaCalusa Posts: 11,874 AG
Put in a new coil and TFI module. When I got done she cranked right up. I ran it for about a minute and switched it off. Cranked the key again and nothing. No click, rechecked my connections, etc.

I did have to loosen and rotate the distributor a little to get to the TFI, but I marked the location beforehand and made sure it was exactly there when I tightened it.

Somebody help me here. What have I done wrong?

    Try cleaning the electrical connections, and then re connect with dielectric grease.

    What about the ignition switch?

    Have you done any research about common problems for that year vehicle?

    My 1990 f250 had an ignition switch break.
    That's an easy check you should have a pin hole on the steering column.
    Push that in and turn the key it should pop right out.
    This not it but in this pic the tab that is on top is what broke off on mine, that was lots of fun too get out.

    Suggest taking this off FL fishing forum & going to Ford Truck Enthusiasts forum.

    You can try Ford_Trucks.com. Did you disconnect the battery? When you turn the key on, do you have power, dash lights, etc? Even if you moved the distributor, it would still turn over but might not start. Auto or stick? It could be the ignition switch or as BT suggested, the neutral safety switch. You can try shaking the shift lever (auto). Good luck.

    I did disconnect the battery for a minute, and when I turn the key it has power and the ABS module activates, lights, radio, etc. It's an automatic.

    I also tried moving the shift lever to neutral and back to park with no results. Where's the neutral safety switch located?

    I am not positive, but the last ford I had to mess with the neutral safety switch was a 92 or 93 f150, and it was on the lower left hand side (drivers side) of the trans. where the shifting linkage meets the trans.

    Double check the battery terminals.Check for 12v at the (s) terminal at the starter solonoid on the inner fender well.(when ign switch is in the start position).I think the wire is red with a blue tracer.No voltage at the s terminal would mean the nuetral switch or ign switch.Gandy is right, the nuetral switch is on the left side of the ****.(automatic)

    Is the neutral switch something that would go bad after the repairs I did? Is the switch something I can manually adjust at the ****?

    Yes it should have a screw that tightens down in a slot.
    A way to check if it is out of adjustment is to try to start it with the shifter in different positions. Make sure you have room in case it does start in gear.
    That would just be checking the adjustment, but not if your switch is good or not.

    Ya a tad redneck but it only takes a min.

    Instead of guessing blindly you could try using a simple test light to diagnose the fault. In less time than it takes to read these posts it would be EZ to check & see if turning the key energizes the neutral safety switch, solenoid, or starter.

    Most of the time I have to work alone.

    Lusa, you have a volt meter?

    Your battery connections are the only thing u touched that could cause it.
    The ignition module and coil wouldnt effect the starter.Any thing else is coincidental.
    Snit happens! Start at the beginning,charge the battery,check all connections and check the solonoid wire.EZPZ
    Oh and yes the nuetral switch is adjustable.

    U can get a 12v test light at any parts house as well as a cheap volt/ohm meter

    REPLACE THE STARTER

    Ford, how do you know if it is the starter or the solenoid?
  • CalusaCalusa Posts: 11,874 AG
    Is it possible that, with the new coil and TFI, that the additional surge of power has caused something down the line to seize up?

    Did I say I hate electrical problems?
    I have had many, and once it is found it's like OMG that was easy.:banghead
  • CalusaCalusa Posts: 11,874 AG
    I have a feeling this one's easy. I never smelled anything burning or fried, or saw any smoke. It's just ......... so close I can feel it ....

    Ok I'll tell ya and it works on other cars and trucks also.
    If your solenoid is making a clicking sound chances are it is not the solenoid, but that is still not ruled out.:banghead
    Cross the power to ground on the solenoid if the starter turns your starter is not bad.

    After that move on, yup a bit more shade tree mechanic.

    Chances are it's the battery or the battery cable connections. When you messed with the battery cables did you twist the battery post? It is possible to break the connection inside the battery if you ham fisted the connections.

    You can bypass (jump) the solenoid, but I would not ground it unless you are trying to let the smoke out.
