1994 Buick LeSabre - Answered Questions & Fixed issues

Could it be coming from the dash??? That car might be old enough to have a speedo cable. Another thought, I know some Caddys that had an automatic park brake release. You had to put it in gear for the Park brake to release. Hope that helps.

try looking on google search ,I found that looking for things in the " images" section of google lots of things pop up,good luck,Gary

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

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.

if a 17 mm bolt head then around 90 lbs if 19mm then 120lbs

Will it hurt the vehicle from it's everyday driving

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

The ECM may be dead .

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.

Any codes?

Why? If you think it is a fuse problem, why not just check them all?

1. Most likely a loose spark plug wire or a vacuum hose is off.
2. look over the engine while running listen for hiss to find vac leak and look for sparks around plugs and distributor
3. turn off
4. plug vac back in and check both ends of the plug wires so there snug

Hope this helps Mike
