Chevy trailblazer stalls when turning gas in the airfilter trouble starting

My girlfriends chevy Trail Blazer Stalls when making turns at low rpms, appears to be studdering at low rpms on the instrument cluster. Has trouble starting and when the battery was tested it gave spikes in voltage. The oil was changed and the charging system and battery were tested the guy said they were all fine but the air filter was soaked in gas (which explained the gas smell)

    swapped out a fuse*

  • Brad Brown Nov 30, 2013

    did you unhook the battery lately? That will cause the 1633 code. Did you clear the codes when it was hooked upp to the reader? What fuse did you replace?

    i have not unhooked the battery lately. It was a fuse for a cigarette lighter. I just cleaned the throttle body and was going to unplug the battery for that

    When you turn the key on, what does the fuel pump sound like? Not with it started, just with the jey on, you should be able to hear it. There have been cases where the fuel pump comes loose from the bracket and when you turn, the pump comes out of the gasoline and the engine stalls, If the pump is on one side of the tank in that model, that makes it worse. One thing you can try is to see if it stalls when the tank is all the way full. IT could also be a wiring issue with the harnesses that control the charging circuit, the battery, the ignition etc. IT could wear or just loose.

SOURCE: wont keep idle, car stalls out

I had this same problem on my 2005 monte carlo, took mechanic a while to figure out it was the idle air control valve. They also replace the idle air control motor.

Sounds like your coil is going out. when they get hot they will go out and when they cool back down they will work normally again. If you replace the coil you will be good to go. Thanks for using FixYa and good luck!

SOURCE: 03 chevy blazer stalls when air is turned on

Sounds like your A/C compressor is seized up and stalls the engine through the belt train when the compressor clutch kicks in.

Try turning the compressor by hand (not from the pulley but from the front part (magnetic clutch), if you can't turn this by hand, it means the compressor is seized up...

As for fixing it, the actual fix would be to replace the compressor assembly, but believe me, that is usually not a cheap fix...
If you want the cheap fix, find the 2 wires that go to the compressor clutch (there is usually a plugin close to the compressor), unplug it and/or cut the wires and secure them to make sure they don't short out anywhere, or even better find the fuse for the A/C and take it out. Of course then the A/C won't work, but the clutch will not kick in and stall the engine...

2003 chevy malibu, takes awhile to turn over and start, idle shoots up and down when started, also it stalls when i take turns

How long since a tune-up? Any applicable trouble codes? With extended crank, you can try cycling the key, on and off, a few times before you crank it. If that helps, have to check fuel system. Use a gage and check proper fuel pressure.
Check and clean the idle air system, see if it helps?

Mt engine stalls when i turn on the heater 2004 trail blazer

The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.

Engine stalls

Assuming you have the correct size battery, this really shouldn't happen! I am assuming the engine is idling at fairly low RPMs, so when the AC kicks on, it kills the engine? It might be that you need to drive the car for a bit so that the engine computer can "relearn" your settings, which disappear when you change the battery. Or, when your battery died, one of your sensors might have gone with it. There is a idle sensor on most cars that raises the idle RPMs when the AC comes on.

96 Blazer stalls when hot on hotest days

I had a similar problem on my 95 jimmy. It was something that took a lot of time and money to diagnose, but now 3 years proplems. Emissions requires the truck to have an EGR valve (exhaust gas recycle) and this deposits gunk (carbon residue) on your MAF (mass air flow sensor) If you catch it in time you can use a carbon cleaner from Autozone or checker Lightly on the MassAirFlow sensor. If not in time you may have to have either the MAF or EGR valve replaced and these are expensive. After a long period of time being undetected eventually the EGR valve will start smelling like sulfer, this means its to late to clean and save!

Hope this helps
