Chevy Malibu Won't Crank- Ignition Stuck

Problem with my 2003 Chevy Malibu. 3800 V6. Question = Ignition will not turn, acts like it is stuck Chevy Malibu 2003?

Answer:
Sounds like the ignition lock cylinder is bad and needs to be replaced. The cylinder is also the sensor for the security system. You could try to spray a little WD-40 in the cylinder, and work the key in and out, turn it back and forth. Sometimes that will free up the cylinder, but it will still need to be replaced. Then the theft re-learn procedure will need to be done.
Malibu Ignition Replacement

Chevy Malibu 1998. V6. Question:
My malibu will crank up but not turn over it will usually start if its warm every once and a while but when cold stall crank not turn over when I turn the car off recently the ignition won't turn all the way off so I have to jiggle the drive staff till the key fully flops over so the car can fully turn off what could this be.

Answer:
It sounds like you have a couple different problems going on with your car. The hard starting and stalling out could be fuel related. Possibly a fuel pump going bad, a fuel pressure regulator leaking. Colder weather usually makes these type of problems happen more often. With the key not coming out and having to jiggle it to remove it from the cylinder, you definitely need a new ignition cylinder. Once that is replaced, you have to do a theft relearn procedure so the car will start.

Question:
The 1st problem was the theft system lights up and my son has to wait 10-15 sec for car to start, our warranty had just gone out when this happened and dealer said it might be ignition theft system. Now the car while running loses power and wont start, after a while it will restart, but while running it will lose power, the fuel filter was changed out.

It doesn't seem to be the fuel pump, the car ran good for about a week and now back to square one, also the service vehicle soon light comes on and of, the local parts store, said they can't put on diagnostic machine or it would mess up other sensors.

Answer:
Sounds like you may have more than 1 problem. First step would be to get the codes scanned. Auto parts stores do not have the ability to scan BCM (body controller) for codes. The theft system has several components. The ignition lock cylinder is the one that fails most of the time, The ignition switch could cause theft and no start problems, and could also cause a stall condition. I would suggest getting the codes read from the PCM (powertrain control module) and the bcm to start. Also have the fuel pressure checked when the car stalls.

All these condition MAY be related to a faulty ignition switch, but without codes, and some preliminary diag., hard to say for sure. You could try tapping on the ignition key and area around the ignition, and see if it may give some signs that a problem exists in that area.

1999 CHEVY MALIBU.
Dash lights = CHECK ENGINE LIGHT codes P1404. Work done to repair = REPLACED EGR VALVE AND GASKET, LIGHT WENT OFF FOR ABOUT 50 MILES AND IS NOW BACK ON. Question = Is there anything else that may be causing the check engine light to come on? What else can I do?

Answer:
This codes is for EGR closed position performance. If replacement of the valve did not fix it, then the next thing to look for is broken/stretched wires at the connector. The cooper wire inside the colored insulation can break. A tug on each individual wire would show the insulation stretching. That is a sign that the wires is broken. There may be a blockage in the EGR port in the intake manifold. This will also cause this code. Let me know if you need more assistance.
