Hello to all my 1994 Isuzu Rodeo dash is flashing and when I insert the keys to start the SUV it doesn't start sometimes but when it does when I hit the breaks, slow down or put it on parking it shots down I don't know what is happening I just have a small thought that it might be the "kill switch" black button that is behind the key I think that is how it's call. If anyone knows a fix or a suggestion etc please let me notice about it.

Thanks

 

I'd check my grounds first there, pal.

You might be chasing a ghost. I had it happen
to me, and it was just a ground wire, under
the battery tray.

Starter would click but not engage, and check engine
light would blink at the same time as the click when
holding key over, and then stop blinking when returned
to run position.

Ground strap, attached better, and cleaned, always fires up
first try.

Worth a shot...especially with your intermittent issues.
My money is on wiring.
