what size motor do you have. it should be under the exhaust manifold on the passenger side

Hello. It seems your car's engine, itself, is the 'ghost'. If your car has a distributor, it may not be 'rotating' as fast as it should. Another day, it 'rotates' just fine. This will cause the 'ghost' to appear then disappear. Good luck and keep me informed; if you want to.

Most is 15mm.need long arm take off the belt.13mm for ground nut may be two to hold at back.

under middle of car next to front of trans. easy to see.

This could be a servo problem, or a clutch pack problem. When was the last time you changed fluid and filter.

What have you checked so far ?Will the engine crank in neutral ? Does it use a security chip in the key ?Does the starter have power at the large post and on the small wire coming from the key switch ?

It sounds to me like your engine coolant level may be exremely low and your engine is probably severly overheating. I would recommend checking your coolant (antifreeze) level and checking for possible engine damage due to overheating.

The bigger question here is whether or not the fuel pump is delivering fuel when it runs. Fuel pumps work on pressure. Once the pressure builds up in the fuel lines it will shut off until the pressure drops, then it turns on again. The fact that your pump doesn't turn off suggests that either it's not pumping any fuel out of the tank or it's not building any pressure. First thing to do is make sure there is fuel in the tank. It's possible your fuel guage has stopped working and is giving a false reading.Start looking for gas leaking under the car. A leak that let's the pump run continuously should leave a very visible wet spot. Look at the top of the tank as best you can too. Loosen the fuel line at the throttle body and see if you have pressure there. Maybe it's pouring fuel into the engine and creating a flooding condition. The fact that it runs continuously would suggest the problem isn't the filter. If the filter was plugged it would build pressure. If you can't find anything here I think you are going to have to drop the tank and start looking in there to see why it isn't picking up fuel, possibly replacing the pump. Hope this helps.

TRY SOME STARTING FLUID AND SEE IF IT WILL START IS SO SWAP FUEL FILTER AND TRY AGAIN

DO A TUNE UP AT 30000 MILES. BACK IN 80S AND EARLY 90S YOU DONT HAVE 100000 MILES PLATINUM PLUGS AND 100000 MILES DEX COOL ORANGE ANTI FREEZE. THE GREEN. ETHYLENE GLYCOL ANTI FREEZE HAD TO BE CHANGE EVERY TWO YEARS. SOME OF THE 91 CARS HAD DISTRIBUTOR CAPS AND ROTORS DONT LAST LONG LIKE THE DISTRIBUTORLESS IGNITION SYSTEM. THATS WHY YOU HAD TO DO A COMPLETE TUNE UP AT 30000 MILES.

Possibly fuel filter blockage or fuel pump efficiency.
I suggest....don't drive until resolved. Risky business to have a stall at any speed.
