I spent four hours gettin it running at the GL auction lot. Ran like crap, knocked severely. I figured it needed an overhaul, but every mile I'd drive it towards home would shave the tow bill. So I drove home, got a nephew to drive me back and drop me off. A couple other winners were there , winching their treasures onto trailers. One had the chain hnging down out of the transfer case. We drove up, I jumped out of my truck into the blazer, started it up and drove away. The other guys looked shocked, but they hadn't shown up until after I had spent the whole morning getting it road worthy.
Anyways, a diesel with one valve not working blows it's intake charge, with full fuel in it, into another cylinder. Where it explodes while the piston is half way up. makes a clang, ruins power. I could look in the intake and see the intake charge blowing back and forth, so knew it had a upper end prob, not just a bad bearing or rod. Anyway, a $3 valve spring fixed it. The later the brand new pump form another auction cost $140, for the brand new awesomeist Stanadyne aver made. Sold it later fro double my money.
Have you tried loosening each injector line, one at a time? It's the equivalent of removing a spark plug wire. That might tell you if you have bad compression. Too tight a valve might cause something like my problem, blowing a fuel charge into the wrong hole.
Injector lines mixed up? If you cross 2&3 on a four cylinder, they won't run, then, turn pump 180 and 2&3 would run, but 1&4 wouldn't, so no difference by turning the 180.
Run it a while, 'spit' on the exhaust tubes, they should all get hot at the same speed, cold ones are not firing.
Oh, well. Good luck. You've been fighting this engine for two uears now, haven't you?
