I own a 1997 s-10 Blazer. The vehicle has lots of power and runs great. However, when I drive up longer inclines the engine will gradually loose power and stall. The check engine light flashes but shows no codes. I can start it again without trouble but it will drive like its running on 2 cylinders until the road flattens out and then it runs fine.

I have changed the fuel pump, fuel filter, ignition switch, and coil.

PLEASE HELP!!!!


Thankyou
Pete

Check that fuel pressure on the road running when it does it.

If the light is flashing you have a engine miss.
How good or what kind of spark plugs does it have in it?
Has the computer been checked on a good engine capable scanner.
It should have a code in history or memory somewhere if the light has been on or flashing?

checked fuel presure while driving and it was down, so i replaced the fuel pump.

Sometimes the check engine light flashes and it doesnt stall under the same conditions.

Plugs should be replaced soon Im sure
