Stalling when turn back on


all stalls end in CEL check engine light on. that is normal
but CEL glow. when engine running , means you had a failure, and it stored DTC error codes, so scan it.
lots of causes. huge list.
get a tune up , tops list.

SCAN it to be sure all sensors work. running.
all fuses in car good.
by stalls , i assume the engine stalls and engine RPM is 0 RPM.
the stall cause the whole dash to light up, all the warning lamps come
on (self test) oil , charge , CEL. come on.
what is important is the stall and the cause.

i will tell you the 3 ways.
lost electrical power to engine EFI system (seems not)
bad engine, (lost compression hot)?
bad spark , spark died.?
bad fueling, lost all fueling (starves and stalls or floods and misfires horribly and stalls (black spark plug tips are big time clue)

if non eof the rings a bell.?
get the car serviced.

this car is newer nicer car, you (we) can scan and drive and log data.
allowing faster easy diagnosis.

Service engine light and no power


Hi there:
First, it is normal for the check engine light to come on momentarily when you turn on the ignition switch and then go out. If it stays on, then you have a stored code that indicates a malfunction of some kind in your engine or transmission control systems.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

I suggest visit some Autozone or AutoShop with OBD Scanner Reader in order to scanning the module to know exactly wat fault code is stored there; note this code number for additional details.

Hope this guide helps.

Transmission won't shift out of 1st and service engine light comes on. goes in reverse and park. goes in drive , just will not shift.


Hi Cindy, As the engine check light is coming it is indicating a problem. Have a diagnostic scan carried out and let your technician determine the actual fault. It could be something to do with the state of engine tune or a defective speed sensor, but may also be a problem with the gearbox. Regards John

Engine light on andcar missing


Hi there:
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

Driving down the road my truck stalls and the oil


First you must find the engine oil pressure sensor, remove the sensor and repalce it with a gauge. Run the engine until hot and record the reading if the reading is between12 and 25 PSI replace the sensor, if the pressure continually drops as the engine warms up then you have a major issue, meaning there is serious engine wear and a rebuild is nesassary.

Engine stalls, check engine light, not fuel filter.


the white smoke as it stalls could be steam in the exhaust. This is caused by coolant leaking into cylinders from a leaking head gasket. You should check cylinder compression next with a compression tester.
