Preface; Did some work to the fuel system recently, ended up switching to and using the rear tank permanently, the front one rusted out. It has been doing fine till today. Today I noticed my fuel gauge was reading around 1/4 tank give or take. Thought to myself I am going to need fuel soon. Going home from work, hot day, A/C on, pulling a mountain, though unloaded, go over it everyday. Almost get to the top and it quits on me. Feels like it ran out of fuel. Got it off to the side of the road, got a ride home, got some fuel and brought my can of ether to help things out a little bit. Poured the fuel in, I had checked the schrader and it spit some fuel out so that was concerning me a little bit. I gave it a shot of ether, hoping it would run on that a little bit and I would not have to crank it so much. I started cranking and spun nicely till the ether hit the engine. Once the ether hit the engine struggled to turn over, much like a gas engine with the timing too far advanced. After the ether cleared it cranked fine, but did not start yet. Went out and tried the ether again, did the same thing. Cranking fast, ether hits and it struggles to crank, and by the way does not fire at all. After those two episodes I quit using the ether and just kept cranking it, and it finally picked up the fuel I had added and ran fine. So I did run out of fuel, I think I have the dreaded broken shower head on the fuel pickup tube. I think all that is explained, but I have no explanation why it did not like the ether when I gave it a shot. I never use ether unless I have a problem and I always have used it with success before when the engine was cold. This time the engine was hot. Is there a reason why it did not like the ether in this situation? There is nothing wrong with it, it runs fine, lots of power, NA, original injection pump and injectors with approx 140,000 miles on it.
