Question about 1994 Chevrolet S-10

1 Answer

1994 chev. S10 4.3

While driving for about 1 to 2 1/2 hours the engine just cuts out no nose just stops. I can then put the vehicle in neutral or park and the engine starts back up. Some times I have to pump the gase pedel and try to start the truck untill the engine catches. Also the oil gauges keeps jumping depending on how much I press down the gas pedel

There is a sensor device, on the right side of the engine block near the front, for the oil pressure that has two parts to it. It is used to control the oil pressure guage on the dash as well as having a switch which has wiring going to the Electronic Control Module, and this ECM input has a software time-out safety feature. After the engine is started, if the indicated oil pressure goes too low or is lost, the voltage to the fuel pump is shut off. This is desired in the case of a crash. This event will cause the engine to quit. On my manual transmission vehicle the ECM will reset if the ignition is turned off for a couple of seconds. It sounds like this oil pressure (aka sending unit) sensor is not working properly, causing the fuel pump power to be removed.....(probably intermittently). About $20 and a few minutes to change if you can get your hands down in there.

You do not wash there newer cars with all of the electronic gadgetry that they have - too easy for the wrong thing to get wet and ..........
I would wait till the engine gets completely dry. Let it bake in the sun for at least a day and see what happens. Cross your fingers because operating some of those circuits when they are wet can often damage them.

Car in park turn key starter engages engine starts and you can hear the Bendix still spinning in the ring gear put car into drive and then they stop spending


Does the starter engage again when you go back to park ?
Shifting from park to drive would cut the circuit from the key switch to the starter. The neutral safety switch prevents you from cranking the engine in drive or reverse.
I would say the key switch is not turning off power to the starter when you go from start to run.

Try starting the car in neutral. Keep your foot on the brake and put on the emergency brake and try to start it in neutral instead of in park. The vehicle is equipped with a neutral safety switch which does not allow you to start the car in reverse or any of the drive gears. You can only start the car in park or neutral. You may have a problem with the shifter or the shifter cable. On some vehicles the shifter cable can be adjusted.

The weld on the manual lever is known to break loose. First, with the wheels off the ground, with the lever in the park position, does the drive shaft lock in park? If yes or no sometimes, drop the trans pan. I bet the nut on the lever camd loose.

Can a 1998 4x4 S-10 blazer be dinghy towed?


Yes it can, just place your Transfer Case in Neutral position.
Shifting into NEUTRAL
To shift the transfer case to NEUTRAL do the following:

Make sure the vehicle is parked so that it will not roll.
Set the parking brake.
Start the vehicle or turn the ignition to RUN.
Connect the vehicle to the towing vehicle.
Put the transmission in NEUTRAL (N).
Shift the transfer case to 2HI.
Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.
Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles equipped with a manual transmission.
Turn the ignition to LOCK.
Place the transmission shift lever in PARK (P), or FIRST (1) for vehicles with a manual transmission.
Release the parking brake prior to towing.

Shifting Out of NEUTRAL
To shift out of NEUTRAL:

Set the parking brake and apply the regular brake pedal.
Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off.
Press the button for the desired transfer case shift position (2HI, 4HI, AUTO 4WD or 4LO).
After the transfer case has shifted out of NEUTRAL the red light will go out.
Release the parking brake.
You may start the engine and shift the transmission to the desired position.
Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

NEUTRAL: Shift the vehicle's transfer case to NEUTRAL only when towing your vehicle.
Good luck and hope this answers your question.

When slowing down & stopping 2005 Mazda tribute sputters and dies


Sounds like it could possibly be a vaccume problem, the computer sees that the vaccume has a low pressure and thus fludding the engine, or visa versa, it's seeing too high of a pressure and cutting the fuel comsumption to a minumum enough to make the engine sputter and die.. Does this happen when the cars in Netural or Reverse or Park? Just Drive?
