New installed starter will not disengage - 1995 Chrysler Concorde

Jeff provides a great answer to the issue

• Jeff Armer Jan 02, 2023. Starter relay contacts stuck closed could be a reason .

  Circuit Description
  Moving the ignition switch to the START position sends a 12 volt signal to the engine control module (ECM)/powertrain control module (PCM) Crank Request circuit. The ECM/PCM verifies that the transmission is in the PARK or NEUTRAL position. With the transmission in Park, voltage flows through the Park/Neutral position switch and feeds the starter relay coil. The ECM/PCM then grounds the control circuit of the starter relay. When the starter relay is energized it allows battery positive voltage to the starter solenoid S terminal. On some vehicles the starter will continue to crank the engine with the key released until it starts or the crank command has timed out to prevent excessive heat build up in the starter circuitry or the ECM/PCM receives an engine run flag.
  

It is ver important that the correct bolt spacers between the starter and the mount be used to ensure the correct engagement - you either have the wrong ones or no spacers installed

Try new starter or even try bridging a screwdriver to engage the starter manually that will tell u if its starter or something else

the wires at the ignition switch are wrong
the power to the relay should only be hot when the key is in the start position and not the run position

The starter solenoid is binding?

Is this a new install? Did you use shim kit?

If it is old then just replace the whole starter.
(YOU WILL NOT able find a replacement return spring easily)

Removal & Installation
Models With Automatic Transaxle

1. Disconnect the negative battery cable.
2. Remove the two upper starter motor retaining bolts.
3. Raise and support the vehicle using safety stands.
4. Loosen the two intake manifold support bolts and remove the support.
5. Loosen the support bracket bolts and remove the bracket.
6. Loosen the starter motor support nuts and washers, then remove the support.

When removing the hard shell connector at terminal S, grasp the plastic shell. Do not pull on the wire.

1. Disengage the S terminal connection from the solenoid.
2. Loosen the B terminal washer and nut, then disengage the electrical connection from the solenoid.
3. Loosen the lower starter motor bolt and remove the starter motor from the vehicle.

To install:

1. Position the starter in the vehicle.
2. Install the lower starter motor bolt and tighten to 23-34 ft. lbs. (31-46 Nm).
3. Engage the S and B terminal electrical connections.
   

When installing the hard shell connector, be careful to push it straight on and make sure it locks in position with a notable click or detent.

1. Install the starter motor support and tighten the retainers to 35-44 inch lbs. (4-5 Nm).
2. Install the support bracket and tighten the retaining bolts.
3. Install the intake manifold support bracket and tighten the retainers to 12-14 ft. lbs. (16-22 Nm).
4. Lower the vehicle.
5. Install the starter motor upper retaining bolts and tighten them to 23-34 ft. lbs. (31-46 Nm).
6. Connect the negative battery cable.

Models With Manual Transaxle
See Figure 11

1. Disconnect the negative battery cable.
2. Loosen the B terminal washer and nut, then disengage the electrical connection from the solenoid.

Hope helps (remember comment and rated this).

My ford f150 did the same thing, so I put the old starter solenoid back in( the one by the battery) and it cured the problem.
Come to find out, the after market relays aren't rated right, to get a good one, and the right one, you have to spend more and get it at a dealer.

Remove starter, remove small screw at copper tab that extends from inside starter housing onto front of solenoid. Remove two screws on solenoid ears that hold solenoid to starter nose. Turn solenoid to disengage the tab that fits between nose & housing. soleinoid should be off starter now. Reverse to install.

It sounds as though the solenoid on the starter is stuck. if it is a used starter a light tapping with a hammer may release it (very light). DON"T tap it if it is a new or rebuilt starter you may void your warranty. If it is a new starter it should have a warranty. If installed at a garage call them for warranty repair if you installed it yourself pull it off and take it back for replacement. Most places I deal with for starters and alternators, either new or rebuilt have least a 1 year warranty. mike
