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 3.1 that rotates but will not start I have replaced the fuel pump and filter now I have the proper fuel pressure and spark so I did a OBD1 test and came up with code 33 which is...

a bad MAP sensor will definately keep the car from running properly, some vehicles run really rough when it's bad and others won't even start.

I have an 1990 buick regal custom and stalls when im griving it then dies can anyone help me on how to fix it.

Sounds to me like a fuel filter.When was the last time it was changed?Because if a car starts and runs till you give it gas under load then dies it is a fuel problem.Start by chaging fuel filter and if problem still persists then next thing to check is fuel pump.

I have a 1990 Regal that sat for a year. It turns over, you can hear the fuel pump run but there is no spark at the plugs.

if there is no spark, you need to check the coil! make sure you have power there, and check the coil wire for power!

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.

I have a 1990 Buick Regal that stalls while accelerating. And then wouldn't start at all. After letting it cool for a few minutes it started but continued stalling. Before this started happening it was...

most likley a fuel pump issue. The only way to know for sure is hook up a pressure gauge and when you have symptoms check the pressure. If you spray some brake cleaner or quick start when it doesnt start and it does start then this is an indication of a failed fuel pump or fuel pump relay. If it still does not start when you spray then you have an ignition issue like a crank sensor or ignition module.

I'm having problems with my '90 Buick Regal Custom's fuel pump. Where can I locate this under the hood, so that I can replace it?

the pump is in the fuel tank. you either have to drop the tank or there is a access hole in the trunk. did you check fuses and relats?

Buick Regal dying

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.
