Question about 1990 Chevrolet K2500

1 Answer

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

1989 Chevy K2500, 350 auto. The truck is hard to start but when it starts it idles smoothly. When I floor it, the engine stumbles a bit but immediately revs up strong. This is after the engine has warmed up after 15 minutes idling.

When I put it into drive, it dies. No backfire, just stumbles and dies. I use the truck as a plow truck only. Just a few weeks ago I started it up and drove it around with out any problems.

Thanks for any insight . . . Jay

    Thanks gmiller442 for the info. I will get some Seafoam in the tank. One thing I did notice the spark at each plug is yellow. I would have expected a blue spark. I put new plugs in, but still a yellow spark. I was going to replace the dist cap, rotor and coil . . . can't hurt!

    Thanks again for your info-very helpful. 32boom

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.

Usually a problem with a dirty throttle body or a faulty idle air control valve. The computer controls idle speed by regulating how much air enters the intake thru the valve.

1989 Chevy K2500 350 will not restart after warmed up? I have replaced Heads, reset timing 0 TDC new plugs, coil, cap, button, module and pick up coil. Engine starts cold runs great but will not restart...


tdc is usually set at 8 degrees BTDC for an automatic and 4 BTDC for a manual transmission. This may help. Does the engine run rough at start up being set at 0TDC?

My 95' Chevy diesel k2500 stalls out when im driving it. it will idle just fine and starts back up right after stalling. truck will drive about 1 mile before stalling again. What Can I check?


I have replaced many injector driver modules on these diesels. GM has redesigned it and i have never had a replacement one fail. This is a known problem for the 6.5 diesel. Unfortunately its about a 500 dollar part from the dealer, and requires intake removal, and some very tight work space to replace.
