SOURCE: 1989 Chevy K2500 - idles fine but stalls out when put into drive.

Sounds like the injectors may be bad or just really dirty. You say that the truck is only used as a plow truck, so I would assume that it sits alot. If you dont add any fuel stabilizer to the tank, the fuel will start to degrade and the will gum up your injectors. One thing you can do is to pull the air cleaner assembly off and look at the injectors while the truck is running. Look at the bottom of the injectors while it is running. The injectors shouldbe spraying fuel with a fan spray of fine mist. If you see any drips of fuel in the this fine mist, that injector is at least dirty or on its way out. I would recommend that you change your fuel filter and then get some fresh fuel and the purchase some Seafoam fuel injector cleaner from your local parts store. Dont mess around with anything else. GET SEAFOAM. If it is in a plastic bottle it is not strong enough to do anything. Seafoam is in a metal can. Dump the seafoam in and run the truck as much as you can. This will help clean out the injectors.

SOURCE: 1999 honda odyssey-engine stalls while driving-electric is fine-

Maybe the solution
There is a recall on the ignition switch,
My 99 Ody with 120K would suddenly switch off and come back while runing, Take it to dealer and report to Honda, Since out of warranty. The dealer would do the repairs estimated at $100 charge to you.

SOURCE: Rough idle

I had the same exact problem on my 2004 Colorado (3.5L). Cleaned the MAF sensor (with MAF sensor cleaner) and throttle body/plate - cleared it right up.

SOURCE: I have a 2000 chevy blazer 4.3l engine\is backfiring

Start by checking each cylinder for spark with a good spark tester. A misifre is either spark or fuel, so you can cut the problem in half. The engine light is probably on due to the misfire.

I have a 2000 chevy blazer and when i drive it all of the sudden the engine stalls. I've replaced the fuel pump and it continues to do the same thing.


I had a problem with my Blazer stalling when I woud stop the vehicle at a red light. I took it into Jiffy Lube and they performed a fuel system clean. It helped the problem however it didnt go away. I replaced the PCV valve and that seemed to help for a day or so then it started in again. I ended up taking the top of the throttle body a spraying carb cleaner in the small hole inside the throttle body next to the large flap. It works great and the dealer said their is a plunger that gets stuck and needs cleaned every so often.

94 chevy k5 blazer works fine cold problem is that when it worms up it stalls backfires into the exauhst and losses power and turns off


Most of the time if it was a fuel pump it wouldnt start at all.Sounds like a tps problem.If there is a check engine light on, it would probably be cheaper to pay someone to scan it, instead of guessing and buying
sensor after sensor.Some of them are quite expensive.
Hope i was of some help

2000 chevy blazer starting issues


swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.
Regards,
