Starter sticking

I have a 92 chevy suburban 4x4 with 145000 miles. It has the 5.7 liter engine. Recently it started acting up like the ignition, or fuel was cutting out. When it finally died, I tried to restart it, and the starter would not disengauge. The only way to stop it was disconnect the battery. When I reconnect the battery, it does not do anything until I attempt to start it. I replaced the starter, it still would not disengauge. I replaced the ignition switch, no change.
The battery load tests good. I am totally lost. It sounds to me like a relay is sticking, or something is back feeding the starter, but the schematics I have do not show a relay in the system. Please help

Did you replace the lock cylinder at the top of the column or the ignition switch as the bottom of the column. I would be suspicious of an internal problem in the column.

I replaced the ignition switch on the bottom. The key cylinder is moving freely. When I turn the key to the off position, all of the lights on the dash, radio, etc go off.

Hopefully someone else can jump in on this to take you further.

Food for thought is the best I can offer. When a bad starter is sent back as a core, the "bad" part is replaced when it is "rebuilt", If it is "remanufactured", all wear parts are replaced. It is typical of poorly skilled rebuilders to miss a problem and the unsuspecting next customer gets a problem that is the same as they had. I'm not saying your replacement starter is the problem, but don't overlook that as a possiblity. Perhaps the starter solenoid can be isolated to test.

Hey hotwire,
Sounds like a short to power on the solenoid circuit. Gonna have to isolate and test along the entire circuit to find it. You can use a meter or test light. Let me know!

I just had a brain storm. I did not put shims in between the starter and the engine block. Honestly I never have, but if the bendix is hanging on the flywheel because of inproper clearance, then it would also hold the starter contacts together to keep the starter engauged. When the battery is disconnected, the cranking stops allowing the starter to return to its normal position. I will put the shims in and let everyone know what happens.

OK guys, I got it. As per my lost post, I shimmed the starter with no luck. Same problem. I started testing the starter circuit. I had mentioned to a local mechanic that I thought the problem was in the starter.( Service Writer made more sense to me in his comment towards reman starters) This starter was a rreman, but there wasn't any logic to what was happening. I removed the starter, and bench tested it. It worked like a champ. I even exteneded the starter wiire on the truck and "hotwired " it so the truck would crank it over. It worked fine sitting on the ground. I thought the problem was only seen when the starter was under a load. Parts store check starter. No problem. REinstalled and connected an external power switch to starter for starting. I hit the switch and it started cranking, and once again would not stop. At this point the sub almost got pushed out the door. Knowing now that the problem was not a short in the starter wiring, I pulled the starter, went back to the parts store, argued with the salesman, and finally bought a new starter, not reman. Went home, put on starter, and it worked well.I went through 2 remans, and a new one would have solved the problem. Of course at this time it would not start. Troubleshot that issue, and found ignition coil was bad, and distributor cap and rotor were bad. I had a typo on my mileage entry in the beginning, but I am a little disappointed that the cap and rotor on these things when new only lasted 165000 miles(HaHa) I keep everything else in tune, but not my daily driver. Thats is it. Hope this helps somebody. A bad reman starter took several weeks of evenings and weekends to find what Service Writer pointed out, and I agreed at first, but did not get agressive and get the new starter instead of trusting the Parts store, which I usually don't do. Sorry to get so long winded, b ut I don't want anyone to go through this again. Oh, one last thing, use extra caution when replacing the ignition switch. If it is out of adjustment, the engine will start fine, but you'll cyr for hours after finally getting it run, just to find out it won't go into gear. All is well now. Thanks guys
