no start after High press oil pump replaced

[kuchman]

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??

Theres multiple reasons it wouldnt start, check out this thread and thank Bismic later if it helps you out ----> Troubleshooting a No-Start condition

its going to take a bit of cranking to get it to fire up after replacing the pump. get it on a charger and crank it in atleast 15sec intervals.

fill up the reservoir first most people dont it helps a bit.

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..

Ok fresh 10w30 and filter still cranking lots of battery power with charger on, it tries to fire like it has air in the fuel fires on a few cylynders but never totaly catches! been tryin off and on for a good half hourr or so

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
