Do this before you do anything else. If this is a 3300 (3.3L) engine, there is a common ground post beneath the air cleaner, under the crossover pipe. It loses contact on these older models. It is among other things, the ground for the ECM, and will stop the car cold. Take the four terminations, which ground a total of 8 wires, loose. Clean it all up, and buff the terminations with some sandpaper to get any corrosion off. Be sure when you're loosening and tightening the nut to use a backup wrench on the hex base of the post itself, or you'll behead the terminations of the ground wires. Snug it all down and you'll be back in business. Be sure to disconnect the battery before doing all this because you don't want to buy a new ECM. Bet this fixes your problem. Good luck.

It depends on which Cutlass you have. If you have the full size gas engine Cutlass, the fuel filter is in the carburator. Remove the main gas line going in the front of the carb. Then unscrew the large fitting from the carb. the filter goes inside that fitting. There is a right way and a wrong way to put it back in, so pay attention to how it comes out. This type of filter should be changed every 2 or 3 months because it's so small.
If you have the diesel powered Cutlass, the filter is a square box type thing on the back of the engine above the intake manifold. simply remove the lines and replace the filter. Rehook the lines, start the car and check for leaks. This type of filter should be changed twice a year, spring and fall because they change the additives in diesel fuel depending on air temperatures.
If you have a Cutlass Ciera you will have different procedures again, unles it has a carburator. Hope this helps.
When you chaged the air filter & sprayed Gumout carb cleaner, you got rid of a little gunk in the air intake, but when you added the fuel injector cleaner (its the same stuff as carburator cleaner) to the fuel tank, you "cleaned out" ALL the ****/gunk/buildup/dirt in the fuel system which has built up since 1991 and sent it straight to the fuel filter, which is now clogged. The reason that the car tries to start, but fails, is that it'll successfully burn up any fuel that gets past the clogged fuel filter, but the engine consumes that small amount of gasoline quickly, then dies. Your solution: change the fuel filter. The fuel filter is located: Under vehicle, driver side, below seating area, near fuel tank, mounted on frame rail in fuel line
The ECM is located right behind the glove box. First remove the negative (-) battery cable. Then remove the front of your glove box, just a few small screws. The interior of the glove box is cardboard and will pull out after removal of screws. Then unplug the 3 electrical plugs and let them hang out of the way. Now, remove the bolts on the side of the bracket holding the ECM IN.
I am having a similar problem, but there is no check engine light. It seems that mine dies at the light or running, if the rpm's drop. I am wondering if the Idle air control valve is bad or possibly the ERG valve?
The mechanic should check on the ignition system first . Check the ignition switch, the ignition coil , the spark plug , the spark plug cable , the distributor assembly and the wires and the fuses.Check if there are worn out or destroyed then replace it. And then set the distributor timing mark and the firing order of the spark plug which is 1,3,4,2.These 1,3,4,2 are the number of the spark plug connecting to the distributor assembly.Then try to start the engine .The cause of the engine back fire is ignition timing not in order.

Did you try checking or replacing the coolant sensor? I think you should replace it along with the thermostat. Are there any problems like sputtering or any unusual noises or symptoms? Smoke, anything?
