Check your spark plug gaps if they are fine go to your idle air control valve or the throttle position sensor if you can raise the rpm's in park but you can't in drive and the vehicle dies the throttle position sensors contacts are worn in that position from everyday use in park your at higher rpm's and the sensor responds to raising the rpm's but in drive the sensor is at a different position and the rpm's are lower and when you try to accelerate your sensors worn in that area and the vehicle dies but I really think your spark plugs gap is to far because once the engine is warmed up the plug gaps spread slightly from heat and if they are already close to or out of spec now the gap gets further and it can't ignite the fuel mixture and that's why the no start condition

I had the same problem. It was the fule filter. Low cost fix at your neighborhood mechanic. I had one that put almost 500000 miles on . When the engine finally quit I sold it to a guy who put a junk yard engine in it and its still running great. Don't give up on it.

SOURCE: wont start security light stays on

My girlfriend had the same problem, so we took it to the local dealer in Costa Mesa, CA and were told she needed a new engine to the tune of 5K. We decided to take it to our local mechanic and he discovered that the “ignition control box”, which apparently has the antitheft controls too and shuts the flow of gas to the engine because it thinks its being stolen when it malfunctions, was causing the starting problem. Once, the box was replaced it worked fine. Because the IBC controls antitheft, it will need to be “reprogrammed” be someone that has access to the proper equipment or the dealer. I think the whole thing was about $800 - $900. Sure beats $5,000

Hope this helps,
B

SOURCE: 2002 Chevy Tahoe sputters and stalls out while driving.....

Fuel filter. Timing/timing chain. Idle air control valve. Idle sensor. Vacuum leak. Probably one of the above, but the filter is cheapest place to start. Change your air filter too, if you haven't for a while.

I have a 95 tahoe i was driveing home from work and it died on me at 55mph, i cranked it while driveing and it fired back up, within a few miles it died again and would not start, still wont start


You need to check it for spark and fuel and go from there. If you have questions on how to test let me know. Don't start throwing away money in parts for it.

Chevy Tahoe sputters than dies


i would first try to replace the fuel filter.usually there filter accumalates debris in the gas tank especially if you you ru the tank close to empty.filter location needs to be traced from the tank toward the motor.you will see a cylinder inline with a strap.part usually runs around 20.00. also when you initally turn the key before start you will hear a hum for about 2 sec. this is the fuel pump pushing the fuel up to motor.so if you hear this pump is working.

Body Control Module (BCM) on both counts. Find a shop in your town that specializes in electrical systems to test it. Beware, these can be intermittent problems, so make sure they keep it until the car does what you have observed. Expect to spend about $450 for the replacment. Dealers quoted me between $700 and $1,100 for the same repair. By the way, a new BCM will probably only last you about 12 months.

93 honda civic ex sputtered and died while driving


Is there any white smoke coming out the exhaust? Sounds like the same problem my friend had when he warped his head on his 91 civic. Any overheating at all? Otherwise another guess would be maybe a bad catalitic converter that clogged up. Hope this helps any, good luck
