When you replaced the injectors did you drain the hpop rails on the cylinder heads. If not your engine is hydrolocked with oil. remove valve covers, remove glowplugs, place valve covers back on with a couple bolts, then attempt to crank over. I bet it will crank over.

If you replaced injectors on both sides of the engine then you need to do both sides at the same time. All it takes is one cylinder to be locked up. Then it will not crank over at all.

yeah you need to pull the glow plugs out before you break somethin! my bud and I just did his the other day, had to pull em all and turn the motor over by hand on the crank awhile to get everything out. all is well now and its runnin great.

ok cool yea i took the glow plugs out and cranked the motor over for a while by hand but i guess i didnt get it all out bc it is still doing that same thing i am gunna try the method with putting the valve covers back on and crank it over a couple times...i also think my starter is going so i just got a new one and i am gunna replace that ans go from there...thanks guys i appreciate the help!

btw did you top off your HPOP res? we had to more than once actually, and after about 10 minutes she fired up and has been running great since...

Is the engine turning over yes or no? You say it does not crank over. To me that says when you turn the key it does not crank. Is the starter making any noises at all. If not how good are your batteries? Are they charged up?

it all ended up being the starter for some odd reason put a brand new one in and the thing turns over better than it ever did befor
