I have a 1990 Buick regal that does not turn over on first attempt and is sluggish to start.


Just to clarify, cranking is the same thing as turning over.
If it cranks but does not start, you need to check the fuel pressure with a gauge before and after you try to start it.
The pump relay allows the pump to run for 3 seconds before the engine cranks to boost pressure in the line. If the check valve in the pump is bad the pressure will drop off when the engine is not running.

I have a 1990 Buick Regal that stalls...


You might try a crank sensor, most of the time if you pull it out you may see a crack in it. It's between the top of the oil pan an the transmission, good luck.

My 1990 Buick Park Avenue dies after 15 miles


Replace the crank sensor as they get hot they will sometimes quit working. The temp light comes on everytime the engine is turned off and the switch is on. Next time it dies spray or pour some water on the sensor then see if it will crank and if it does you know what it is.

Need to know the location of cam sensor on 1990 buick regal


It's just under the water pump. You most likley need to replace the magnet that is on the cam gear to fix it. The sensors hardly ever go bad. The timing cover will need to be removed to fix the magnet.

Which Solenoid to buy???


Replace the crank sensor to fix it. It's next to the crankshaft pulley which has to be removed to replace. Next time it gets hot and shuts off , spray or pour some water on it and see if it will start. If it does then you will know what to do.
