i have a 2000 f350 7.3 and there was an oil leak at the hpop and it was the plug in the back. i didn't notice it till i removed the whole pump. so i installed a new oring and installed the pump and filter housing back on. i filled the hpop resevoir with oil and let the filter bowl fill up with fuel. i also chagned 2 injectors #6,8. i rolled it over a couple of times and it won't start to try firing till theres full oil pressure. i cranked it over for awhile than this morning i went and got a battery charger and i put a volt meter on the batteries and they don't drop below 11.5 volts when cranking. i have the block heater plugged in to help it start. i'll crank it for 15-20sec than stop and let the starter cool down for 3-4min than crank it over again. do i have to bleed the fuel or oil lines? theres no check engine light on. the engines trying to fire when i crank it over it just won't run.
When I did my injectors it cracked open the rear oil plug on the passenger side head and it fired the next time I tried. I had been trying for 30 minutes before that. I don't know if it was what made it crank or I gave up too quick. It takes a while.
had the same sort of drama,there is a plug in the bottom of the high pressure oil pump with a pin attached and it has a nylon check ball that sits on top of it,if the ball falls out it will not start,also after fitting a new pump it took a fair bit of cranking to get it to go
