Actually it's common with the half tons. Highway gears, lighter weight, and, on the civy trucks, OD gear = good gas mileage.
Sure, my school bus has a lever I pull out to stop the engine. One morning I was sitting in the office when a full-time driver pulled up wanting to switch busses because hers had no lights or signals or nothing. I was told to take the kids already on to the school by the back way, and halfway, there, the alternator suddenly kicked in and all the electrical accesories started working. Bus ran fine with no juice. The alternators on these old things don't always start charging in the cold.Just to nitpick, that isn't entirely true. The IP has a fuel shutoff solenoid that requires constant power to allow fuel to flow. If it loses power it will shut off the fuel and the engine will stop. That said, it is a fairly low-draw solenoid so the battery alone will keep it engaged for many hours.
I wonder if it is possible to replace the shut off solenoid with a mechanical shut-off? Then, as long as the mechanical fuel pump is retained the engine would truly require no electricity to operate![]()

Thanks for the info. I'm curious about the Biodiesel/veggie oil thing. But if your getting 23 mpg out of a 5400 lbs 20+ year old vehicle that's pretty amazing.

I think a mild lift, enough to clear 35's. With the tight lift laws in NJ I can't afford to go much over 48".
He ever SAS his S10 Blazer?
