Message: <blockquote data-quote="maccor" data-source="post: 57510" data-attributes="member: 6107"><p>Been trying to get the old 751 with Pug motor running....special props to Tazza for helping me with lots of things to check. Here is what I know so far.... Was running, throttled back to idle to check something and it died. Would not start again. Coolant level low, but temp gauge never went out of 'good' range... Checked timing, all right on, crank, injector, cam... Checked compression,#2 cylinder a little low, 285psi, but rest above 350psi... Checked fuel solenoid...operating.... Replaced glow plugs with new. Verified they are getting voltage and are red hot on ends Pulled injectors, cleaned and checked. Did not mix up parts, all pins were moving when put back together.... Verified good spray pattern on injectors before re-installing. Did not buy new copper seals, but they seemed pretty good, reinstalled with existing just to see if we could get it to run.... Bought new battery and starter spins motor better than ever before... Replaced primer bulb... Bled fuel system of air through bleeder on injector pump... Installed clear hose to watch fuel, no air bubbles... Sprayed wd-40 in intake while cranking, didn't help... Still won't start. At a total and complete loss as to what it might be. I've searched and read every thread on 751's here to see if it could be anything else. Got reasonable compression, glow plugs working, cranks, getting fuel. Shouldn't anything run with that? About to sell it for parts and chaulk up the $8K I payed for it as a lesson learned..... Any and all suggestions would be much appreciated. TIA, Mike</p></blockquote><p></p>
