1999 Jeep Grand Cherokee: Stalls and Quits Running?

The jeep starts and runs fine,then suddenly in between driving it stalls and then quits completely.It will only start after waiting for few minutes.
But same procedure for stall and quit repeats.

In this case there are few basics that needs to be checked.
It can be weak or dirty fuel pump or faulty fuel filter or its the issue with spark plugs.
But if all this are checked ok or are already been replaced properly then,

the most common cause of this is a faulty crankshaft position sensor. It sends a signal to the computer for when engine is at TDC that controls sychronizing the firing of the fuel injectors and plugs. when this signal is lost, then engine just dies. When engine dies, the computer as well as the crank sensor resets, so signal is restored which is why it will recrank without waiting 10-20 minutes.And starts in few minutes say 3 to 5 minutes.

Also you can try retrieving the error codes stored in the ECM computer and see if there are any codes in it.


To pull codes, turn ignition key to on-off-on-off-on, leaving it in on position. The check engine light will flash a series of blinks. Count the blinks. Three long blinks, pause, followed 2 long blinks would be code 32 for example.

Most of the time the cran sensor will not set a fault code unless it has a hard failure - no start condition.


This details will help.
Thanks.

2000 Toyota Camry: Idling and Stalling Problem?

In most of such cases you get check engine light on dash.If in this case there is check engine light coming Up on dash,then get the error codes scanned,so as per the error codes retrieved further problem troubleshooting can be done.

But if in case there is no check engine light coming up or no error codes are showing up then other possibilities are to be tried out.

The most common issue for idling and stalling is related to the IAC or Idle air Control valve. It gets built up with carbon and sticks. This is a duty cycle rotary valve on the bottom of the throttle body. The throttle body has to be removed to clean this valve. The throttle body plate and bore need cleaned also. The other issue is the EGR valve. It is notorious to stick in the on position and this will cause the engine to stall also. These 2 things need ruled out first. These two items will not normally set codes either.

This details will help.

1999 Toyota Camry: Erratic stalling and high engine RPM at idle?

The Engine stalls after brakes are applied.In some cases the Car dies.Sometimes car is going to rev up at a stop or just die at a stop.
This all are sudden problems.

This irregular problem makes troubleshooting bit difficult.
Because at one moment the car is running absolutely fine and then suddenly next the problem starts.But goes away after some time.

But this problem is noticed by others too.

Based on your description it sounds like the idle air control motor or IAC is sticking. This can cause very erratic and high or low idle depending on what position it sticks in. This IAC is a duty cycle Rotary valve that the computer controls to set the idle. When carbon gets built up in this valve it will stick very erratically. This is the first place to start. The throttle body has to be removed then the idle air control valve removed from the bottom of the throttle body and cleaned thoroughly with carburetor and choke cleaner. The throttle plate and bore also need to be cleaned within the throttle body itself.

Normally when you start push 200,000 miles and if the fuel filter has not been replaced it is probably a good idea to replace the filter. However this would be more maintenance oriented for replacement. The fuel filter generally will not cause this type of erratic behavior of stalling and high engine RPM at idle. If you get this problem to get repaired at Auto garages or dealership then,Most dealerships will not want to clean the idle air control motor. They will want to sell you a new idle air control motor they are about $125 I generally recommend trying to clean them first it doesn't work then you're only out the small amount of time it takes to do the job and not the $125 for the parts. If you get the idle air control motor off and it looks scored or damaged then you know that you need to replace it.

This details will help.
