Could the mass air flow sensor cause 98 Jimmy to not start? It only turns over and begins to start but boggs out.

    It was a warped distributer! due to a screw in the rotar that was too long.

MAF sensor usually won't prevent an engine from starting but would cause erratic idling after the engine is running. The problem is more likely fuel related (dirty fuel filter, dirty fuel injectors, failing fuel pump)

Yes it could cause it not to start or could start and run very rough. Are you sure you are getting proper fuel pressure? Could be many things that would cause it not to start and run though. Is your service engine soon light on the dashboard lit up? it is where your gauges are.

    I have a 1999 gmc jimmy that will start and run fine for a few days then will turn over but not start for days


    I wild have to work on this until I duplicated it, then check the vehicle while it was messing up. You could have one defective component even if you just replaced it. (Fuel pump, ignition module, crank sensor, etc.) You could have simply a bad coolant temp sensor, or maybe your mass air flow sensor causing problems. You could try unhooking your coolant temperature sensor and seeing if it wild start. This makes the pcm look at a default value. You can try the same thing with the mass air flow.Do you have access to a scanner when it is messing up? Have you checked for spark at the plugs? Have you checked your fuel pressure? Sorry, I would have to actually work on it.

    The truck stalled out when driving. Sounds like it wants to start, but won't fire. Codes found - P0410, P0128, P0141, P0102. Please help. Daughter's truck and she leaves for college in a few days.


    code p0410 refers to secondary injection system--malfunction===causes wiring--air valve--air solenoid--- ECM
    code p0141 refers to heated oxygen sensor-2 bank1-heater control -circuit malfunction===causes --wiring--oxygen sensor--ECM
    code p0128 refers to coolant thermostat --coolant temp below thermostat regulating temperature==causes mechanical fault (thermostat stuck open)
    code p0102 refers to mass air flow (MAF) sensor/ volume air flow (VAF) sensor low input===causes wiring short to ground--MAF/VAF sensor ECM

    Check engine lght on and 2 codes p0103 and p0112


    P0103 HYUNDAI - Mass or Volume Air Flow Circuit High InputPossible causes- Dirty mass air flow sensor
    - Dirty mass air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor electrical circuit poor connection
    - Intake air leaks
    - Faulty mass air flow sensor
    Tech notesBefore replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
    P0112 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Low InputPossible causes- Dirty air filter
    - Intake air temperature (IAT) sensor harness is open or shorted
    - Intake air temperature (IAT) sensor electrical circuit poor connection
    - Faulty intake air temperature sensor
    When is the code detected?An excessively low voltage from the sensor is sent to ECM.

    98 Jimmy has 5 codes (multiple misfire; egr; mass air flow; intake air temp; manifold pressure) Was dogging out on me and the other day it quit. Now it turns over but will not start. Checked and it is...


    I would start with the Mass Airflow and EGR sensors first, because they can cause the misfire codes and the intake pressure and temp. Just because the air filter and hoses are clean and free flowing doesnt mean the computer can see that. If your Mass Airflow sensor died, as far as the computer is concerned, there is no air going into the engine.
