Cranks will not Start

bigcountrysg · Jan 18, 2012

So my truck will not start. But it cranks all day long til the batteries are dead. I have scanned for codes nothing comes back. Passes buzz test, everything seems to be ok. I pulled and inspected the lower oil pressure pump.

It was running just fine and then all of a sudden it shut off like someone turned the key off. I was cruising down the road at 55mph when it happened. I am at a lost and not much money to take it to a shop.

I just replaced the engine. Which I had to do because of an injector failing.

I had the engine running, and now I am back to a broken truck and I am getting frusterated.

IPR good? Oil in the rails?

I'm going to guess there isn't any smoke out the exhaust while cranking.
Rpm tach move while cranking?

bigcountrysg · Jan 18, 2012

my tach has never moved while cranking even when it was brand new. It is a 2002. It did not spit or sputter or nothing when it died. It just was like someone turned it off.

To my knowledge there is oil in the rails. I believe it is an oil pressure issue. I have had the chance to try and crank it over since I inspected the oil pump.

Where you located? If you were close by I could swing by and put my scan gauge on it and see what its doing while cranking. But the chances of you be close is one in a million.

onebad7.3 I have Auto Enginuity. Oh I also replaced the IPR, and swapped the ICP out as well.

Oohhh huh this is a strange one. Well if the icp and ipr all look good while cranking, you sure you have fuel?
You have fuel bowl or do you have that deleted?

Spend $10 on a Motorcraft oil filter from walmart & see if it makes any difference. A buddy of mine was having low oil pressure issues running a NAPA filter. Switched back to Motorcraft & the truck runs great again. At this point it's worth a shot.

I think I will change the oil and filter and see what happens.

Cat_rebel · Jan 18, 2012

Change the oil & throw a Motorcraft filter on & pull a plug on each side oil rail & see if they are full of oil.

moose99psd · Jan 18, 2012

remove the plug ontop the hpop res and stick a screwdriver or ziptie or something and see where the oil level is at.

Oil pick up tube? If it just shut off I say it's an electrical problem. Thinking ignition, electrical for the injectors, fuel pump. Are you sure it has fuel?

What is your icp while cranking? Did you check all your fuses especially the fuel pump fuse. Had one come in that did the same thing. Had a blown fuse.

bigcountrysg · Jan 19, 2012

Fuel Pump is an Airdog2 wired seperately then the factory fuse box. I still need to get the radiator in and see what the icp is during cranking. But it aint the warmest in Michigan.
