I just tried to crank it it didn't fire one of my batteries is bad so I think it wasn't spinning fast enough it only Spain maybe 400-450 rpms I'll pick up a batterie tomorrow
I only let it spin for about 20 sec I didn't want to burn up the starter from not having enough power

currant is directly related to voltage so i wouldn't be too worried about harming the starter with week batteries unless it causes excessive cranking, but the ECM limits this anyways.
if it was me i would prime the filter again without opening the bleed screw, unless you think there is still air in the filter, till it the bulb was hard, take the grid heater (intake air heater just above the "Y" in front of the turbo) off and pour a cap full of gas down the hole and start her up. then take it for a test drive and if the batteries still are bad after getting a good charge then i would look into replacing them
good luck, Jason

doesn't seem like you are getting any fuel, double check the rubber fuel lines coming out of the filter and leading up to the CP3 for any kinks or collapsed hoses.
check the large connectors on the top of the engine for bent or pushed back pins, make sure the ECM and FCIM connectors are fully inserted, etc
do you have any OBD tools that can read fuel pressure? the ECM needs to see 1450 PSI (10 Mpa) before it will open the injectors.
if all else fails, take off the fuel supply line on the filter and connect a hose and container to it an fill it with fuel, prime, see if the fuel level goes down when cranking the engine over

i dont have a scanner and ill recheck all the plugs tomorrow thanks for the help im sooo ready to be done with this project i also replaced all the rubber fuel lines with new ones, is it just not spinning fast enough to get oil pressure? it still has the old oil with a little diesel in it from the old injectors
