20 Most Recent 1994 Buick LeSabre Questions & Answers

The chance of the Power Train Control Module (PCM) failing is very small, about 3% per industry research, so expert ndguy2481 is giving bad advice, it is more likely the crankshaft position sensor or the ignition module have a problem when they warm up. Run a test on the PCM to retrieve the trouble codes, I know there will be some. The connector to do this test is under the dash below the steering wheel under the dash panel.

Sounds like you a loose 12V connection at the relay box.Locate the relay box and when the engine is running wriggle the wiring harness or shake the relay bow and see if that's when the engine stalls. You may even have a bad / loose ground to the relays.

no the crank shaft sensor would not stop it from turning over

Classic signs of coolant in the oil and since heads were repaired and sealed, it could be a cracked block.
Coolant is mixed in oil and coolant impedes lubrication of engine thus hard to turn over and start.
One last hope is to drain crank case, refill with fresh oil and new filter.
Add Barr's leak "copper" )(looks like liquid copper and costs about $10) sealant to coolant fluid. Run the engine a few times to full warm up, each time observing for tell-tale white smoke from exhaust. Check dipstick level between each cycle.
If problem subsides, go buy a lottery ticket as you're very lucky. If not, a new engine or short block is on the menu.

Good Luck

Check the actuator motor and rods on the heater box inside. The motor moves the doors in the heater to direct the heat to the area you request. It is a small motor on the driver side or in front of the heater above the dash.

Apart from my other suggestion, you can get a new lock and key from a scrap yard. Get someone to fit the new ignition lock. To pair the antitheft system, you have to disconnect the battery for 2 hours and then reconnect with the key in the lock.
