I was playing with an old Autocar last night, had a 220 Cummins. We put some half-decent batteries in it and attempted to fire it on ether. (fuel lines were in bad shape, and no fuel in the tanks.) After 2 or 3 minutes of cranking, the batteries were pretty much shot, but it never fired at all, or even really came close. My question is, is there anything other than weak batteries, that could have been the problem? Thanks for the info. guys.

No compression maybe? Or not enough. Maybe the rings are stuck.

| AJ-----No fuel at injectors = no start ! I did'nt believe it either, but about 40 years ago my mechanic proved it .Get a bucket with fresh fuel and short piece of fuel line .

| It may be just me and my opinion only so don't take this to heart as an offense. Either is one of the most damaging things in the world for an engine. it may be allright to give an engine a slight whiff of the stuff to help them fire but without them having diesel to run on it will never keep running. another thing is a compression ignition engine fires from the heat created by the compression. Diesel needs around 400 degrees and high pressure to fire, Either lowers the temps in the cumbustion chamber. Becoming a double edged sword while the either may burn at the lower temps the diesel will not so too much either and you cet a hydrostatic lock. I'm sure Glenn has seen it where an engine was being cranked and suddenly it locked up. I have seen rods bent and broken and even head bolts stretched and broken. I even saw 1 crank shaft broken from this on a V 8 cat. before trying to start any diesel engine the fuel system needs to be purged of air or all of the either in the world is not going to make one run and do a lot more damage than good.

Unless you have fuel getting to the injectors, all the ether in the world will not lite it off. Ether will warm the cylinders, but that's all. No fuel, no fire, no run!

I know I'll get yelled at, but I've run motors on plain old ether. A motor should be able to run on ether alone. I've done it several times at work when trying to get a stubborn motor that lost it's prime to run again. Would I do it to my own motor on a regular basis? No, but with some common sence, it can be done with no damage. But the other factor is that I had good batteries at the time, so you do need good cranking speed for it to fire. But if you have fresh batterys, spraying ether directly into the intake and it is not even firing at all, you have other problems.

Saw one that had rain water down it the down pipe and it was full up to the engine but not in the engine If it cant push air it cant pull air.
