There are a great number of things that would cause the problem you are having. You can check your fuel pressure regulator and fuel system for proper pressure and volume. You can also have the ignition control module tested. Another possibility may be a failing crank or cam position sensor. Visualy inspect the harneses for all of these componets for damage. Finaly perform a wiggle test while the vehicle is running to find bad connections.

The freon has to be recovered before removing the a/c compressor.There is a special machine that does this.You can not just remove the hoses.They are under pressure and if you get freon in your eyes you could go blind.You can have a shop recover the system and then you can remove the compressor and then fix it but you need special tools to remove the pulley also.Then once you have it back together you can have them recharge it.On some of these they give you enough room to remove the pulley without taking the compressor off.Hope this helps.Good luck.

since it is the drivers front door it could be the outside door handle , the rod that goes from the handle to the lock asbly or the lock asbly its self take the door trim panel off and then loos inside the door and latch the door with the door open. open the door with the outside door handle and watch the rod and the lever that the rod is pushing down the lever might not be pushing the lever down far enough to release the lock. If the lock does not open try pushing down on the lever and see if the lock releases if it does ck the outside door handle for cracks along the hinges of the handle I have found that most of the time that it is the outside door handle cracked and the rod is not moving the lever far enough to release the lock.

CHECK FUEL PUMP RELAY IF GOOD WITH DOOR OPEN TURN KEY ON LISTEN FOR SHORT FUEL PUMP NOISE. FUEL PUMP IS IN TANK.

couter clock wise! some times you might have to aply heat to get them to free up.

All washer fluid comes from the same reservoir. If your not getting washer fluid to the rear washer, it could either be a plugged or broken washer fluid line, or rear washer fluid pump.

It should be located very close to the oil pan and it will look much like this...

At the carb fuel intake there is a fine screen to keep the debris that might form in the fuel tank out of the carb. It sounds like that might be the problem.

when you say car lost power bought a new battery.sound like alternator not charging battery.with car running your voltage at battery should be 13.5 volts or 14.5 volts it not alternators need replacing.have garage replace alternator if faulty because 1993 to 1994 cars if you disconnect battery car would lose memory causing car not to idle.the car will stall out at a stop light or stop sign whole lot.it would relearn itself but the stalling out dangerous around a lot of traffic.

When you replaced the ECM, did you use a nice coating of di-electric grease? That helps distribute the heat from the ecm so it doesn't over heat. Also check your ignition wiring going from the battery to the ignition switch. Check for any loose or broken connections. A local shop can help you find wire shorts BUT BE ADVISED, Most shops charge a $70 an hour fee to diagnose electric problems. Thats not to fix, only find problems. I highly recommend a self search first.

have you checked them for signal from the ecm, for that you will need a noid light, there will be juice going to the injectors and are activated by ground to the ecm, if you are not getting spark the injectors won.t cycle, good luck

Yes, if everything is still connected properly, except that the injectors are no longer seated int he valve head, then you should see little spurts of gas coming from them when the engine turns over.

Be aware though, that it might not be your fuel injectors that are the problem. You need to finish checking the rest of the car before making that assumption.

Once you know the injectors aren't firing, you need to check the fuel filter and the fuel pump to make sure the gas is getting from the tank to the injectors.

You should have a fuel filter located on the passenger side of your car near the gas tank. Follow the gas lines under the car to find it. It is good to change it anyways, but you can check to see if gas is coming from the tank to the filter by removing the rear line

** BE CAREFUL, Gasoline is EXTREMELY irritating to the eyes and skin, and it WILL come out when you remove the line from the filter***

If it is coming from the tank to the filter you don't have to check your pump. Then replace the rear gas line, and remove the front gas line going to the engine and make sure the filter spits out gas while the engine turns over as well.

If there is no gas getting to the fuel filter, you will need to check your fuel pump, which should be located inside the gas tank. You can check it by getting under the car while you have a friend turn the key to the "on" position, but not starting the car. Do this 4 to 6 times to make sure you hear a little "Click, woosh" type sound that lets you know the pump is triggering.

If you have gas coming from the tank, through the filter and it is still not coming through the injectors, then you will need to rebuild your fuel injectors.

This is not hard to do, and consists mostly of changing the little gaskets in the injectors. But be aware that there are lots of small parts and the job cannot be rushed. Also be aware that lumina fuel injection systems are very sensitive. Make sure to disconnect your battery cables before removing the injectors from the system.

Time for new spark plugs, spark plug wires and possibly a new distributor.

THE FUEL IS PRESSURIZED BY A FUEL PUMP INSIDE THE FUEL TANK, THE INJECTORS ARE OPENED AND CLOSED ELECTRICALLY BY THE FUEL INJECTION COMPUTER KNOWN AS THE ECM, THE COMPTER/ECM RECIEVES INFORMATION ON WHEN TO INJECT FUEL AND FIRE THE SPARK PLUGS FROM THE CRANKSHAFT AND CAMSHAFT POSITION SENSORS, HOPE THIS HELPS
