starter strain when hot

I have a 1985 Lincoln Mark VIII. The starter seemed to drag intermittently, then started to drag and bearly turn over the engine when trying to restart
when hot. Ultimately it would not start at all when hot, and you'd have to wait 15-20 min's. The alt and battery are new, as is the waterpump, radiator & hoses. I took it to the shop, and was told the solenoid was bad & had it and the starter replaced. While it starts much quicker when cold, and you don't have to wait as long for it to cool down to resart, it still wont start when hot. ANY IDEAS????

Is it a 1985 Maek VII, or a 1995 Mark VIII? Either way, it's most likely the starter motor; have starting current draw checked, hot AND cold.

You need a new starter motor/solenoid. Usually, problems with hot starting are a good sign the starter isn't much longer for this world..

In article <vfl_c.205930$UTP.77741

The OP stated the starter and solenoid were replaced.

It's pretty common, it depends where you get your rebuilt from. Cheap rebuilt alternators are the worst (sometimes they just sandblast them, replace the regulator, and resell without any testing, or wire inspection).
Also, electronic/electric parts tend to fail either when very new, or when their service life is approaching the end, so it's not unreasonable to find that it's the starter again.
The other thing i could think of, but it would be a longer shot, was that the engine was being overheated whenever the OP is driving, and when he tries to restart, it's just too tight to turn over, but once it cools, it'll go.

Yep the starter and solenoid were replaced. It was done at pep boys. The starter is a bosch rebuilt. The radiator, water pump, thermostat, all hoses, and coolant, so the engine is running at normal operating temperatures. As with the old starter, the new starter seems to bind and almost kickback as if there is too much compression in the engine, it very different from the weak battery kind of drag.

How many miles on the engine? Could it just be carbon buildup increasing compression?

Has anyone checked the timing?

the engine has about 140,000 miles, never been worked on. I have not had the timing checked.

try pulling the coil wire off when it acts up. see if it cranks normaly. If so, you might need a module or the timming set back a bit. It could be carbon build up also. You really need the battery and starter checked. Get the starter draw checked when it acts up to be sure that isnt it. It shouldn't pull more than about 250 amps. And it shouldnt pull the battery down past about 10 volts. your symptoms do sound like a bad starter. I wonder if there is a heat shield for the starter that is missing too.....that could cause the drag.
