S10 Kill Switch
 
Hey Everyone!

I just installed a kill switch on my '95 S10 4-banger pickup truck.

I shot video of it and will post that sometime for you.

In the meantime, I will go test some engine-off-coasting.

This is using a momentary-on switch on the stick shift to interrupt the fuel injection wire through a relay.

The advantages of this over using the key-off,back-on is that my trip odometer will keep running and my radio will stay on. It has about a 5 second "reboot" time for the radio to come on when you turn the key to "on"!

Now I can save gas without missing my radio program.

I will go for a ride and let you know how it goes!

Yesterday, I installed a kill switch in the truck.

Today, the CHECK ENGINE LIGHT no longer comes on, but I am having another problem instead!

I have no power when I put the gas pedal down farther than about half-way!

This gives me terrible acceleration, and I can barely make freeway speed. I can slowly accelerate if I am level or slightly downhill.

Uphill, things start slowing down because I can't push the gas pedal down far enough before it starts losing power!

Also, if I rev the engine up real high, when in neutral with the parking brake on, it sort of shutters and snorts.

Is this a "fuel-rich" problem? When I give it gas, it's getting too much gas, and I lose power?

When I installed the kill switch, I cut the wire to the fuel injectors, and added a momentary off relay in-line to it to turn off the engine.

I put a jumper back in so that that wire is connected directly again (no relay) and am still having the same problem.

Please don't tell me that that's a special wire that has very particular resistance that effects the injectors or something like that!!!!!

What could be wrong with the truck?!?!?!

I have no idea if the problem is from the kill-switch or completely un-related!

Thanks in advance!

Your catalytic converter might have given up the ghost. The 95 Sonoma (essentially an identical truck to yours) I had ages ago acted just like that when the cat got backed up.

I drilled holes in it so that it would run until I could get it fixed.

Odds are, it's the 2nd cat that truck's had in it's lifetime, maybe even the original.
