1988 chevrolet celebrity starts but has no power to run
Is this a 2.8L vin W? I saw a service bulletin that said, do not replace maf sensor for maf sensor code. You install a new mem-cal. The new memcal doesn't use the maf signal, but does use the mat. If the update had been done on your vehicle, there should be a decal under the hood to notify you about the update. They did this because of problems with the maf sensor, at the time.
Just to add, problems at higher rpms, check for a blockage of some kind, air--fuel--exhaust. Use a gage and check proper fuel pressure.

1987 Celebrity Fuel Pressure PROBLEM- The car is
No.. if there was a leak big enough to lose all pressure you would see fuel running on the ground. There is supposed to be no air in the system.. so air would not come out of the valve.. just gas. Next check to see of the fuel pump is running. Possible that it is not. When you turn on the key the pump should run for about 2 seconds to charge the system. Than when the engine starts the pump will commence running.. This is controlled bu the fuel pump relay. Which is controlled by the computer. You should be able to hear it run.. you may have to remove the gas cap and listen at the gas fill point.You can jump the relay to check if the relay is bad.. They are pretty cheap.The fuel pump is in the gas tank.. hard to get at if it needs replacing. You have to drop the tank. If you do this remove all the fuel you can from the tank. This series of GM cars did have fuel pump problems. (REMOVE THE BATTERY CABLE IF YOU TRY TO REPLACE THE PUMP)
Next remove the Fuel filter (its under the car) blow through it to see if its clogged. Replace it weather it is clogged or not. If it is clogged it could kill the fuel pump because it would make it work too hard. If It is clogged and you replace it.. car might start.
If not its probably the fuel pump, They can run and still not pump fuel if they are bad.
One last thing.. DOES THE CAR HAVE GAS IN IT? i HAD A CUSTOMER WITH THE SAME PROBLEM AND SOMEONE HAD STOLE ALL HIS GAS !!

I have 86 celibrity, electric
What your doing when you touch the test light to that 3rd wire is actually closing the circuit and powering the fan, like the temperature controlled switch should be doing once the engine warms. That sending unit would be screwed into the cooling system where the water can touch it and most likely is in the radiator lower tank or bottom of radiator side tank. Find that sensor and test the wires for power when engine is hot and fan should be on. You could put a toggle switch on it to activate the fan until you get the proper sending unit/sensor.
