automatic transmission. starter/solenoid tested ok. but starter will not disengage when trying to start.?

Question

please not starter/solenoid all tested ok. they are not the problem. it does disengage when key turned off. not a key problem or ignition switch problem, these tested ok. there is a cause that i could not find on the internet under a starter problems search. thanks

Answer 1

In some cases a very small spring diseengages the bendix from the flywheel after you release the ignition switch. If the starter is misaligned with the flywheel it will hang up. Some starters require shims between the bell housing & the starter. Lubrication on the shaft under the bendix could help.

Answer 2

Another thing you could look at is when you are hooking up the wires to the starter, they are not touching each other not unless they go on the same post together. If the wire that engages the starter touches the wire for the ignition switch, it will have a steady source of power as long as the key is turned on. If it has touched the battery wire it will stay engaged until the power is removed.

Answer 3

Considering everything else has been checked...... the ignition key switch itself (the electrical component which unplugs from the backside of the ignition cylinder) may be faulty keeping the starter engaged because it continuously supplies power to the solenoid. Replacement is the only solution

Answer 4

Yes, starter. If it won't release the flywheel, look to a bad Bendix gear. See http://www.sacskyranch.com/wornbendix.jpg to see what I'm talking about. That is the part that moves forward to engage the teeth on the flywheel and turn the motor over. When it starts, it's supposed to move back out of the way. Yours is not. Unless you have very very very teeth on the flywheel (not likely) you have a bad bendix and changing out the starter for a new one will correct the problem.

Answer 5

if you are working on a small block chevy you need to adjust the starter depth with shims. Some mopars had a big starter bolt hole on one side that allowed the starter to be adjusted

Answer 6

sound,s like electrical ......short circuit / ground fault......hook a 12v. test probe between the solenoid [small terminal]...& a good ground......the only time this circut should be hot is when you turn the key to the start position......not when returned to the run position...........if this is the case you must search for a short circut........or a ground fault situation .....this is a painstaking process......start with your battery cable,s & your engine ground strap..........many time,s your charging system can be the culprit......also try pulling fuses till the light goe,s out......but many time,s a shorted wire can cause this.......also a bad ground can........electricity will search for a ground if it,s normal ground is interupted.........checking all moving part,s usually yeild,s result,s.....but not allway,s.....sometime,s theese situation,s can be a real pain..........hope this help,s...........good luck!

Answer 7

improper alignment of the starter will cause this...when the Bendix gear is activated by your ignition key it engages the flywheel...improper alignment will not allow the gear to disengage.

Answer 8

how about a hot wire that is grounded accidentally? does your starter have a solenoid ON it?

Answer 9

try different starter..check ring gear fir messed up teeth
