I ahve a 2003 f350 6.0litre, Just replaced the High press oil pump, sensor, all hoses and o rings. The tuck will ot start as i crank it the oild press rises to the 3/4 mark on the gauge and it seems to try and fire on a few cylynders but never does start. any ideas??

No reservoir on the 6.0l..
It just takes lots of cranking. Remember to wait between cycles so you don''t burn up the starter. Took me about ten minutes to get mine fired. Also, you can pull the fuse for the ficm so you aren't dryfiring your injectors..

It is going to take a few times of cranking... Mine just caught and fired when it did. Never had any stumbles... It did take some time though.. Did you ever get her going??
Now is the time to start double checking everything...

It has fired a couple times will not idle when it does and doesnt have maximum pms when you floor it, doesnt seem to be on all cylynders, when it is cranking and almost starting it pings and bangs like it is full of quik start, it was brought to me towed out of a ford dealer as a no start they diagnosed the pump,being part of our fleet our company towed it back to me, wish they would have left it there now
