Starting Problem from rollover

[Policeathome]

I have a 1997 f250 with a 7.3. It was involved in a rollover crash and was running while upside down. It is now right side up and I have removed the glow plugs and removed the oil from the cylinders, changed the fuel filter, checked the fuses but the engine won't start. All the engine will do is turn over and over. I have been cranking it over for the past two days trying to build oil pressure. While cranking the engine the oil pressue gauge on the dash shows below low. I cannot find an emergency fuel shut off. I have also opened the fuel drain valve and cranked the motor to bleed the fuel system. I am out of idea's. The motor has 70,000 miles on it. If anybody can tell me what else to do I would greatly appreciate it. Thanks.

Do you have any way to hook up to the ECM while cranking? Seeing ICP values would let you know the hi-pressure system is still working.

I don't have a way to hook the ecm up. I took off one of the hoses that feeds oil to the oil rail and cranked it over and did not see any oil being pumped.

I am arranging to have a friend come and test the ECM. If the High pressure system is working what should values read? Or am I just looking to make sure that the high pressure system is just doing something?

if you took of a High pressure oil line off the head, and you didnt get oil while cranking, something is def wrong. oil should blow out of that line like a fire hose lol. HPOP or LPOP grenaded from running dry maybe while upside down?

Thank you Sir. I'm going to check the ECM hopefully later today.

The oil is full correct? Both in the crankcase AND hpop res.? Injectors wont fire if their isnt full oil in both

Like Matt said above..... Make sure your oil levels are full. Especially the hpop reservoir. The lpop is less than $100 and external. If you aren't building base oil pressure, it won't fill the reservoir. The reservoir can't feed the hpop. The hpop will NOT fire the injectors. Fill up your oil, charge the batteries and give it a go.

To all that helped me with advise, Thank You so much. This 1997 f250 7.3 is the first diesel that I have ever owned and I did not know of the second reservior for the high pressure pump or alot about diesels for that matter. Thanks to all your guys advise I found it and checked it and found that the oil was 7 inches down from the top. I filled it up 4 times while cranking in between fill-ups and then, Music to my ears, it fired and now runs good.
You guys are awsome. Thanks again!!!
