Does it start back up right away or do you have to wait a while?

    Thanks for hitting me back. It starts right back up but does the same thing again.

    Here's what I would do. Pull the air tub off the filter housing so that you can spray carb spray into it and still have the MAF sensor plugged in. Have a helper start the vehicle. When it starts to stall give it a shot of carb spray (carb spray is flammable so keep that in mind should you get a backfire). If the motor continues to run than you have a fuel issue. If the car stalls than its a spark issue.

    Another thing you can try is unplug the MAF sensor and see if that makes a difference.

    I'll try the carb spray. The MAF has been disconnected for about a week. The car ran better without it being connected. Tricky..

I had an identical problem with my 88 Scottsdale. After a week of head scratching by my local dealer, and $1000. worth of shop diagnostic time, they found a bad distributor shaft. Apparently, there is some sort of star wheel on the end of the shaft which has lost magnetism. Replace the shaft.

The temperature sensor is where I would start. If the sensor tell the computer that the engine is cold it will initiate the warm up mode which includes advancing the timing along with a rich fuel mixture. Unfortunately, there are many sensors that assist in controlling timing and fuel mixtures that it is difficult for me to give you a guaranteed solution.

sounds like youve really done your home work all that comes to mind now is try a cam posistion sensor this would keep your car from starting as well if that is good you can aslo try a crank sensor. you will get all of the readings that you are getting and these sensors can still be bad.

1992 caprice will start but wont stay running, if i disconnect the temperature control sensor it will start and idle perfectly for about 15v-20 seconds, then will stop. whats the deal???


Temp control sensor when disconnected goes full rich. But then computer senses open circuit and shuts down You need an ohm meter to test it. You need to find the values of that sensor

My 1994 Plymouth voyager will start up then shuts right off. It will stay started as long as i am giving it gas any ideas on what the problem might be?


Your actually not giving it gas,your moving the throttle
plate on a dry system & also the Throttle Position Sensor

So check the voltage on both side of the TPS Sensor

One side goes up & the other goes down

The computer has a 5 volt reference,so you will see
a little less than 5V closed & movement down to 1V
or so & the other side 1 to 5

The next thing would be to remove & clean the AIC
air idle control valve if you have on

Put a lt1 engine in 1994 caprice it skips and wont hardly go up hills and back fires


Hello! are you using the harness for that year LT1? the fuel air mixture is controled by the Manifold Absolute Pressure (MAP) sensor, the Throttle Positioning (TPS) sensor and the Oxygen sensors...When you put your foot in it without O2 sensors there isn't any control over fuel/air mix and ignition advance if the MAP and TPS aren't connected...I'm assuming your using the LT1 ECM...Guru...saailer

Remove the water pump belt. Start and see if the noise is gone. If the noise is gone you have a bad component that is driven by the belt.

Car takes a few seconds to start & shuts off immediately


how old is your battery? because if it is weak the idle air control solenoid will not sit in the right location thus the vehicle will stall and wont stay running .replacing a weak battery will fix this problem .
