Just jump it.interior lights etc can just bring it down.or put a charher on.not nessarily anything wrong.my xcab had a bambi hit.it was in the body shop and then no start.i put a jump box on and it started right up.

 

it needs a new battery anyway. I'm getting dressed to go hopefully fire it up now. Wish me luck.

 

10.2 volts was the lowest I saw, bouncing around 10.5 while cranking. 13.5 with the pump running. 12.5 with the pump and glow plugs. Then crank and it drops to 10.5 and starts fluttering. This is with a jump, a small charger, and a third battery hooked up. Two new batteries from Advance auto. My charger says they are 100% charged. So I believe it switched to trickle mode.

any way it has the Same symptoms, strong crank but no fuel. I'm showing 60psi on the regulator. I don't think I have any thing else to boost the voltage. And I don't think I should have to hook up so much to get it to fire up? I would understand a rough start but a no start? I'm fearing the hoop is going��. Please anything else I can try. I'm getting desperate! I just changed the oil, before the voltage tests.

 

thanks to mrdiliac7.3 for coming out and helping today. Unfortunately still no start
. Anyone have a link to hoop testing procedures? Thanks

 

how old is that starter? sounds like its dropping off badly when cranking.

 

I've had the truck about a year and 20,000 miles. Same starter that came on it. 264,000 miles total. It spins pretty good still. It's just not fireing the injectors. No smoke or sputters. Tach comes up like its supposed to. With the new batteries I think it's spinning faster. But that makes sense, to me at least. I'm not expecting that to be an issue quite yet. A family friend, I just found out, is a diesel tech. He says I should be looking at the hpop. I'm hoping advance will gave a gauge to borrow to test the hpop.

where is the injection pressure regulator? And how do I test it?

it should be meeting all the parameters to start. That's the confusing part.

could a new starter help my voltage drop at start up that much? I didn't have any issues before? That's why I'm stuck on fuel delivery. Sorry I really do appreciate your help and support. Im Just not prepared to throw parts at it.

 

IPR (injector pressure regulator) is on the HPOP. Bottom driver's side of it. Takes a really deep socket or modified socket to get it out. The connector for it gets soaked in oil and deteriorates over time. Also, the tin nut on the back of it has to be good and tight. Not over-tight, because you'll ruin it.

ICP (injector control pressure) is on the driver's side head. That's the one that you check for oil / wet connection.

Have you checked all your engine bay fuses / relays yet? Namely #22... it's the fuel bowl / IDM (I think) relay. But if it's blown, the injectors won't fire.

 

checked #22, the big 30amp or 50 amp just behind the air filter. It was good, replaced #4. I believe it was for trailer breaks or something. It didn't help.

what do I do with those sensors once they are out?

how do you like your t500? If I end up needing a new one I want to upgrade

thankz

 

If the ICP connection is wet, just replace the ICP sensor. I'd check the IPR wiring before I condemned the IPR. There's not much fixing them; there's some o-rings you can replace, but there's internal stuff to them that you can't get to with standard mechanic tools.

I love the T500. It brought back some life to my old stock injectors, and feeds my new ones just fine. As far as my decision to get it, it was a no-brainer. It's a 17* pump, has the modified drain-back upgrade, and was cheaper than a SD HPOP.

 

check the hpop resivour for oil level.

with that voltage falling off I would have the starter checked.IF it is worn and having excessive amp draw that could keep the level down enough to not fire the idm. THAT is a BIG IF!!

 

great, 4 things to check out tomorrow. Would it be worth it/ possible to do a superduty starter if mine is bad? By check it, do you mean take it to an auto store and have them hook it up. I need to go back to carquest for the alt. core anyway. Sorry for being a pain in the rump. This is my first diesel and the first real issue. It's very sad to leave my truck home and drive my wifes Kia to work.

 

its almost time to start trouble shooting the 1964's issues. My wife really wants her car back. And to cold and icy for the motorcycle. I need to start buying better toys!

again thanks for the help. I'll be back tomorrow with updates.

 

yea,remove and have it bench tested. also check all connections including engine block ground also.

ahh oldies are better..and I have car payments

 

So the starter brushes were worn Down pretty bad. So I bought a "new" starter, and got a gauge to check the hpop. This will have to wait till tomorrow, went on a wild goose chase today. A shop about an hour from home said they could load test the starter. When I get there the story changed. $200 for either what that had rebuilt already or to rebuild mine. But because they were jerks, liars, and higher priced. I went to carquest $180 and nice, helpful guys.

 

new starter and hpop gauge installed. Reading 250-275 psi while cranking. Pretty sure that's to low. And I pulled the plug off the icp, behind the ac compressor with a 3 prong plug. It had some oil in it, assuming that is unacceptable also. Going back outside to check the ipr.
