Hmm, been a while since I played with one of them, but I do recall a simular problem. Try this,,, locate your ECM that you replaced,find the orange wire, and trace it back. I have found breaks in this wire in different places, mostly in the harness running under the rad support. The orange wire is a power wire for the ECM.

94 chrysler town and country stalls after getting to a normal temp but wont start back up till its cooled down.


The crank position sensor could be bad.Check the injectors & fuel pressure regulator with this test.Hold the gas pedal to the floor while you crank the engine.Does it start??If yes,the fuel pressure regulator is bad or you've got a internally leaking fuel injector.Let the engine idle,pull the vacuum hose off the regulator and see if gas is inside the hose or gas is seeping from the regulator vacuum port.If yes,the regulator is bad.You can shut the engine off,wait 5 minutes then pull all of the spark plugs.If a plug is wet with fuel,that cylinders injector is leaking.A bad ignition module or ect sensor can also cause a no start.You can do the following test when the problem is occurring.Remove the air intake hose from the throttle body,spray carb cleaner or starting fluid into the TB opening, reinstall the hose,try starting the engine. If it starts and runs for a few seconds then dies,you've got a no fuel problem. If it doesn't start at all,you've got a no spark problem.

94 camry died and won't start we have spark, fuel and compression and a code 31, changed the map sensor still no start


Yes I do believe that fuel is there. Are the injectors working, some time you have all but no fuel. While cranking check if power is there for injector socket.remove the air cleaner pipe the to the inlet manifold spray 2,3 puf of aero start and see if she run for few second. Take care as you spray, first spray and then start the car
If yes you can figure it out the problem
Let us know how it goes. i hope this is some help to you

My lumina won't start it will start from the


Sudden no starts are usually gas or ignition related. That's why the mantra check for spark and check for gas. If you check for spark at a spark plug and have a blue snapping spark, the ignition is probably good. To check for gas, best to check fuel pressure, as high fuel pressure against the injectors ensures that proper amount of gas will be sprayed out by the injectors. Do you hear the fuel pump buzz on for a couple of seconds when the key is turned to on? If not, try banging on the bottom of the gas tank to see if pump will work. If it does, you will need to replace the pump-may work a couple more times by tapping on the tank, but the pump is basically gone.
If gas and spark is present, one would next need to check the injector circuit.
If spark is absent or weak, it could be the crank position sensor, ignition control module (under the coil pack), cam position sensor, or the pcm.

When my 92 chev van Lumina gets warm it stalls and won't start till It cools down. What could the problem be.


You'll need to get more information. Find an auto parts store that offers free engine code readouts and have them tell you what the engine computer has detected. This will shorten the long list of possible causes. Post again with the results - you may get to post your own solution.
I've had a bad fuel injector driver transistor in the computer (throttle body injection) and an ignition module do this to me.

Car starts and cuts out after 2 to 3 seconds. fuel


When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.

I have an 1988 chev 350 5.7 liter , my injectors will not work, there is fuel getting to the tbi, but somthing is telling them not to open, it was running bad now no fuel, i unpluged the map sensor. and...


you should have over 9psi while cranking with injectors working to start. if there is not enough presure it will not start. The computer tells the injectors to open, it actually controls the ground side of the injectors with power side always hot. the computer NEEDs the map sensor or it will not start, it needs crank and cam location sensors from the distributor, the TPS, etc. Plug all sensors in, check fuel presure, clear codes and start over, checking codes to determine what isn't working.

No fuel injectors, intermittently


With the key on, do you have voltage at fuel injector, use a test light?
Engine cranking do you have spark at the spark plugs? I'm just trying to see if you have more than one problem? I don't know how much testing you have done?
Is there a purple wire with white tracer at ignition module, Engine cranking, there should be a dc pulse on that wire? If not, the computer won't ground the fuel injectors. In my opinion.
