airbound..
When I woke my diesel after sitting a long time,it was a bitch to get it fired up the first time..I used a gallon jug for a temporary "fuel tank",and put the fuel line and return line in it..had to loosen ALL the injector lines,just cracking a few didn't do it!..cranked it until the batteries died twice,before I finally got it to start..
I eventually found dry rotted fuel lines were letting air seep in,after I finally got it to start with ether,as much as I hated to use any..after I fixed the lines and got it running that first time,it has always started good so far..
I added an electric fuel pump right after the gas tank,and a set of manually controlled AC G60 glowplugs..had to swap in a rebuilt starter drive bendix--it got wounded from using starting fluid..disable the glow plugs if you feel you must use starting fluid,by pulling the 2 prong plug off the top of the glow plug relay on the drivers side inner fender..its really bad for a 6.2,they don't like ether--it can shatter pistons and hurt other things too...I used it as a last resort..some say WD-40 works too,and isn't as potentially harmful..
If you got fuel at the injector pump coming in,then the lift pump must be working(fancy diesel name for a fuel pump--its on the block just like a 350)..be sure the filters aren't clogged..if you got fuel at one injector,even just a sqirt,the pump is probably ok,just still airbound..
Dont crank it too long without letting the starter cool down awhile..they are not cheap--it cost me 38 bucks just for a REBUILT starter drive--a new one is 75 bucks..whole starter was 150 at the cheapest parts store..
Rule #1 on a diesel..NEVER LET IT RUN OUT OF FUEL!!..
...especially a GM diesel,that has no "priming pump" to get the air out easier..
I think the addition of the electric pump helped my truck start much quicker,like it primes the injector pump some..
..Good luck!
