Yes an OBD 1 meter will give you a better idea as to what the problem is,however it would be more cost effective to find an OBD 2 meter with the capability to test OBD 1 cars.I do have the same problem with my 88 Lasabre,the 3 codes coming up would be the cam shaft sensor($20),the ignition mudule ($140),or the ECM ($80),I found that on mine the number 3 cylinder does not look like it is firing when I inspect the spark plug,but the only code I get # 41.I'am going to start with the cheapest part first.If you have a basic understanding of the mechanics of vehicles(or a haynes repair manual) you could probably replace this yourself.If you already found the solution to this problem please email me at mikehitchner@comcast.net so that I can fix mine.Thanks

Buick cars don't have them. From the fuel pump relay under the hood, the pump's power wire goes directly to the gas tank and the fuel pump connector.

If your pump is not turning on, check for power on the gray wire at the gas tank electrical connector while someone cranks the engine over. The pump wire, I think it is gray, should have battery voltage when the engine is cranking. If it does, you probably need a new fuel pump. Dropping the gas tank is no fun, it is a dirty job, not real difficult, just not a fun relaxing afternoon.

You may need a shop manual to get the testing procedures. You need to know if the ignition module is getting power and a signal from the cam and crank sensors.

There are 3 bolts inside that have backed out, this is a tough job. You have to have special tools to complete this job. You have to pull the pins on the side after disassembling to access the bolts.

Check the condition and operation of the idle control valve.

Its a faulty idle air control valve.You can take it off and clean it using a non-chlronated brake cleaner and a wire brush or and a scraperor you can replace it with a new one just make sure to reset the computer afterwards by disconnecting the ground cable on the battery for 30 seconds then start it.
