My 1994 Buick Lesabre
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 heat/vent/defrost control panel does not
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.

Why, all of a sudden, does it sound as though its misfiring?
- Most likely a loose spark plug wire or a vacuum hose is off.
- look over the engine while running listen for hiss to find vac leak and look for sparks around plugs and distributor
- turn off
- plug vac back in and check both ends of the plug wires so there snug
Hope this helps Mike

Feul injectors not pulsating
The voltage for fuel injectors go hot with the key on. The computer switches the ground on and off, check voltage and ground.
If the computer doesn't ground the fuel injectors, you'll have voltage on both legs.
If computer doesn't see rpm signal, it won't ground the fuel injectors. If no rpm signal check the crank sensor and ignition module, plus wiring circuits. Don't replace anything unless your testing points in that direction.
