Question about Cars & Trucks
If it sat that long, a fuel hose can swell inside and pinch off fuel flow. If the tank was really dry, flakes can plug the pickup sock too. Try this. pull the small diameter wire off the starter and then hold the key in the start position. This will run the pump without cranking the engine. If you can hear the pump running, keep the key in the start position until the fuel lines are full. The pump will slow and become quiet. When that happens, put the wire back on the starter and try starting it.

Apollo, I would first pull all the plugs out and give a little squirt of something like seafoam or even just a bit of engine oil into each cylinder, you may have lost the seal between the rings and cylinder walls and this will help. You also need to confim for shure that you are not getting fuel before you worry about the pump. You can check this at the fuel rail, either by opening up the line, or in some cases you may even have a schrader vale(like a tire valve) on the line that you can press. I suspect that you do have fuel, but the injectors are not oppening due to the old fuel sitting in them for so long. These can be removed and taken to a shop that cleans injectors, and then reinstalled with new seals. And yes I do belive that there is a fuel pump relay in the fuse area, you need to do a search to find out wich one. These can be jumpered to activate, but untill you have done everything else i wouldn't worry about it. Oh, I asume that you have checked for spark? If not, you can pull a plug out and with the wire attached you can hold the base of the plug against the block, while wearing gloves, and see if you get a spark when some one cranks it over. Remember, you must have spark, compression and fuel at the right time in the proper ammount, and it will run.

Testimonial: " He knows what he is talking about. Great suggestions, thanks"
Sounds alot like the ignition sensor. In my old Chevys it was under the dist cap, mounted on the dist itself. Mine was flat, slightly curved rectangle shape, with two flat prongs coming out both sides. If it would get an internal break in it, you cant see it. I would have the same problem as you, part was only about $12. And comes out with unscrewing two screws.
Might want to give it a shot.

You didn't say how much fuel is in the tank when this happens. Some of these old GM cars will starve for fuel if the tank is near empty and you are braking or stopping with the car facing downhill. It could be rust or scale in the fuel tank clogging the screen around the fuel pump inlet. Sometimes, putting cleaner in the tank of an older car will only cause more debris to loosen up from the inside of the tank and make the problem worse. If the problem gets worse, I would guess tht a new fuel pump/sloat assembly is in order. You may have to have the tank removed and cleaned or replacedd with a new one to prevent the problem from reocurring.

Fuel pump relay is just above the brake booster, change your spark plugs and wires. Check crank sensor. And reset and re scan your car. Code 12. Means ur computer is scanning well. You have to wait . Each code flashes three times. 12 x 3 then all trouble codes x 3 each. Then 12 x 3 again. To conclude scan
