Unread post by shane » Sun Dec 23, 2012 3:13 pm

THIS CAR WILL START EVERYTIME AND AFTER 2-3 SEC. SHUTS OFF AS IF YOU JUST TURNED THE KEY OFF. WE ARE STRANDED IN NEW MEXICO AFTER A CAMPING TRIP... CHANGED GAS, CHANGED CAMSHAFT POSITION SENSOR, STILL SAME RESULTS. FUEL PUMP SEEMS TO BE WORKING CAN HEAR IT EVERYTIME, AND WHEN PUMPING GAS OUT OF LINE IT PUMPED LIKE A CHAMP. NO BACK FIRE, NO BURPS, NO HESITATION TO START, JUST WON'T RUN PAST 2-3 SECS, IF YOU GIVE IT GAS IT WILL SCREAM TO 3-4000 RPM'S AND JUST SHUT DOWN... PUZZLED. DON'T HAVE A LOT OF CASH LEFT TO SPEND ON IT... WHAT IS GOING ON? AIR FILTER IS CLEAN. CODES MENTION O2 SENSORS, BUT MECHANIC SAID IT WOULD STILL RUN, BUT BAD. GAS MILEAGE ALSO WENT DOWN THIS MONTH BEFORE PROBLEMS... CAMSHIFT POSITIONING SENSOR CAME UP ON THE CODES AS WELL THAT'S WHY WE CHANGED IT... HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! CAR HAS 195,000 MILES ON IT AND UP UNTILL NOW RAN FANTASTIC... I MEAN REALLY SMOOTH... IT DID START UP 2 TIMES BEFORE THIS, I KEEPED STARTING IT OVER AND OVER AGAIN, AND IT STARTED. NOW IT WON'T AT ALL... HELP!!!!

Ok for starters, please don't use all caps here!!

Secondly, you most likely have a security issue, and you're replacing sensors and trying other things for no reason. Have you noticed if the security light is staying on? It may also say 'theft' instead of 'security'. If so, the most common thing to go out would be the ignition cylinder and Passlock housing. When these fail, it will cause the car to only run for a couple seconds and then die. You'd really need to get the car scanned for body codes to see for sure if this is the problem.

You would need to replace the ignition cylinder, not the switch.
