Starter problems HELP!

[GT Convertible]

I have a 1992 GT Convertible and every time i go to start the car, the starter continues to run for 2-3 seconds after the car is running. i have put a new starter, solenoid, and ignition switch but it still grinds. any help is appreciated.

you may need to shim it. where did you purchase the starter and for how much? i'm having issues too as mine stays engaged after the engine cranks. it only does this on cold starts tho.

I forgot to mention that i did shim it, and it didnt help. it does it everytime i start it, hot or cold. i also forgot to mention that it is an automatic. i dont think it is the wrong flywheel or anything since it is all original. its been baffling me since i bought the car 2 years ago.

Is the block plate (thin steel plate that goes between engine block and transmission or bell housing) still in place? If not, that would cause the problem.

I didnt pay attention when i was under it but next time i change the oil i will check it out

Do you have a fender-solenoid lug with only a relatively small wire on it?
If you have 4 or 6 AWG cables on both fender-solenoid lugs, someone might have read something online, gotten confused, and wired up the circuit incorrectly.

The solenoid does look like it has too many wires on it, but if i unhook any of them it wont start.

The early aero foxes had a non-piggyback-solenoid on the starter. The later aero's (like yours) have a piggyback solenoid on the starter from the factory. If someone incorrectly wired your fender solenoid for an early (non-piggyback) starter, you could have inductance issues depending upon what was done. This would allow the starter to run-on.

If your starter cable is on the same lug as your battery cable (and about 100 other wires), you should be ok. If your starter cable is *not* on the same lug as the battery cable, then more info is needed.

Good luck.

If they put on a new type of starter, and hooked it up incorrectly, then it would do exactly what you said.

See what type of starter you have. You can tell by if there are one or more wires going to the starter, and if there's a relay on the top of the starter.


Here are some pictures:
Uhm, the old/original style is the dirty starter, and the new style is the new starter.

Here are the install instructions for the Ford min-starter:

http://www.fordracingparts.com/download/instructionsheets/FordInstShtM-11000-A50A75B50B75.pdf

From the instructions: (Bold and caps is their format.)
! ! ! WARNING: DO NOT INSTALL A JUMPER WIRE BETWEEN THE BATTERY TERMINAL AND THE SOLENOID BLADE TERMINAL AT THE STARTER TO AVOID THE USE OF THE # 12 WIRE. IF DONE, VOLTAGE IS GENERATED TO THE SOLENOID BY THE STARTER SPINNING AFTER THE RELEASE OF THE START KEY OR BUTTON, CAUSING THE STARTER TO REMAIN ENGAGED, RESULTING IN SEVERE DAMAGE AND EVENTUAL FAILURE OF THE STARTER ! ! !

The diagram in this post show what the solenoid wiring is supposed to look like for 92-93 model cars.

Mine looks like the starter on the left one of the new style starters and its hooked up right, ive done it twice.

I'm gonna check this out tomorrow when i get off work. I've heard that a warped flywheel can cause the same problem. is this true?

So, you have it such that:

1) The big/fat wire on the starter's relay is always live with +12V.
2) On the relay/solenoid on the fender, you have a big terminal (the one that's switched) with only the small wire that goes to the relay on the starter.

Just about any other way, and you'll have the starter "act like a generator" and produce electricity while it's turning which will activate the starter's relay until the current draw kills the relay. Note that many electric vehicles, and some newer gas engines, use a combo integrated starter/alternator. There's no magic, no hand waving, just standard electro-magnetic theory.

My fender relay/solenoid is relocated and "underneath/besides" my ABS module that I have mounted on the Driver's side fender. So, I don't have an easy way for me to get a picture of my fender relay/solenoid.

If you have it hooked up correctly, then you likely need a spacer. Or, maybe the stater of flexplate have dings/nicks.

Good Luck!

Here's an old picture of where my fender relay/solenoid is now. But, that was also before I put in the mini starter. The fender relay/solenoid is near the arrow on the right.

i have to check all of this out. i've gotten a lot of good information. the mechanic couldn't tell me anything close to any of this!

Take a picture of the fender relay/solenoid.

I don't think that you can post a direct link yet with your number of posts (min 50 needed?). You can also PM me the link to the picture.

Or, do something like saying that the link to the picture is:

We're smart enough to know that means:

that should be the pic of the solenoid.
