Thought adrenaline hpop was shot.. turned out no oil. NOT starting?

[85_305]

Alright long story here guys. Truck is a 2002 crew cab, 6spd, short box, 7.3. It has 433k on body, about 80k on motor. Truck has bully dog 6pos 4bank tuner, 1.0exhaust housing, stealth adrenaline hpop, intake, and exhaust.

Truck was driving fine. One day, it started acting goofy and shut down. Had the fuel injectors/lines purged of air. It ran fine for a few more days. Then it died on the side of the highway. Had it towed to Ford dealership. First they said IPR is shot. They replaced it (for a LOT of money). Didn't fix the truck. They said hpop is shot. Gonna be like 3 grand. Efffff that! So we picked up the truck. We bought a used hpop, and towed the truck to the house. We started tearing the stealth adrenaline hpop out, and out of curiousity, I pulled the oil dipstick. Just a smidge was barely touching the tip of it. Cleaned the dipstick, NOTHING was touching it. ZERO oil. We thought "sh*t, this hpop's fine, there's just no damn oil to fire the heui!". We put the stealth back together (didn't fill the hpop reservoir), filled up the fuel bowl (by cranking the motor), and we know there is oil flow because the pass-side head from the hpop wasn't in tight and it was flowing all over the head/valley. The truck took a good 2 gallons of oil to hit the Full mark on the dipstick.

Truck just cranks and cranks and cranks. We sprayed ether, the truck just cranked faster. The rpm's aren't registering upon cranking... and the oil-gauge does register a bit of oil when cranking it. All the fuses are intact.

I think the truck only smoked out the stack when we sprayed ether in there. We were cranking on the truck for a good hour, so we know for a fact there is oil in the reservoir/hpop, and fuel in the bowl. But it sounds electrical to me, since the ether didn't even wanna fire it.

Are we talking a cps here?

Did you fill the oil in the truck while you were at it?

Yes I'm editing my story now.. it took a good 8 or 10 or 12 quarts... it came up to like 2 gallons I think.

Even if the problem was electrical it should have fired on ether. The only reason I could see it not firing on ether is lack of compression . Hopefully you had you GPR unhooked before you shot it with ether.

i would say probably cps but you need to put it on a scanner

I thought ether was a no-no? (Sorry, no help here. But it's at least a bump ttt)

I would almost think so too.. i'm stumped. I dont understand why it didn't fire with ether. Which leads me to think perhaps the icp or cps...

Are my rpm's supposed to fluctuate while cranking this motor? I know some 7.3's DID fluctuate; they show the 250 rpms while cranking then they immediately show the idle rpm when it starts. Because this truck isn't showing rpms.

I think it's ok in short moderation.. but it's a sure-fire way (excuse the pun) to be sure if a truck will or will not fire.

Ether is a no no, unless you have your glow plugs unhooked or relay unhooked. Ether and glow plugs is not a good combo, it has the possibility of lifting a head or an explosion. I would check your compression, as long as your motor turns over the ether should fire it. Nothing electrical will stop the motor from firing on ether, diesels are compression ignition motors ( I know you know this) so in theory it should start if the motor has compression.

These trucks only hold 3 1/2 (+/-) gallons right? I think you were a few minutes away from locking up your motor if you were 2 gallons low. Which probable means your compression (motor) is toast.

Thats why I'm thinking the motor has lost compression.
