LB7: 03 LB7 won't start after changing CP3 pump
Okay, Pensacola diesel ripped me off blind, bottom line on that subject. I ordered a pump from a different outfit in Illinois, installed it today, primed and cranked the truck over 3 times and like magic it purred back to life. This ends the saga of the POS Pensacola CP3 pump. Buy from a... -
LB7: 03 LB7 won't start after changing CP3 pump
Alright I talked to Dave at PD this morning and he says it's the fuel pressure regulator. I bought the pump without a regulator because I already had one that I had purchased several years ago. Anyway, I ordered one of PD's regulators to see if it makes a difference. If the regulator was bad... -
LB7: 03 LB7 won't start after changing CP3 pump
Actually, I did internet searches for injectors and pumps, and I saw good and bad reviews for ALL of them. I actually saw quite a few good reviews for Pensacola, and I spoke to the owner of the business by email, and by phone. We shall see how this works out, and I'll let everyone here know it... -
LB7: 03 LB7 won't start after changing CP3 pump
I just hooked up a clear hose directly to the outlet and cranked it over. I have fuel flow, but just about no pressure. It's a hooped rebuild, and I'm a bit pissed off. With what I'm gonna have to go through to get that pump back out again, I'm angryyyyyyyyyyyy :mad: -

I finally put a pressure gauge directly onto the discharge port of this pump and it puts out no pressure at all. A bit of fuel comes out of the relief port, and the gear is not spinning around the pump shaft. I marked the gear, the shaft, and the nut with a sharpie, and that line doesn't... -

I'm leaning that way, tothemax. A pressure gauge is needed. BUT BUT BUT, don't they bench test the pumps before selling them?!! LOL! -

Yeah all the connectors are in place. It's a Bosch reman from Pensacola diesel. I called them and they said they don't do the rebuilds themselves. I'm meticulous about keeping fuel ports covered when I have things disassembled. You're right, though, I need to know what pressure the pump is... -

Okay I marked the nut, gear and shaft with a sharpie, and took video. It's spinning without any slippage. I am just completely baffled now. -
LB7: 03 LB7 won't start after changing CP3 pump
Okay I checked all of the hoses, routing, clamps,etc, and I plugged the end of the banjo bolt that the FPRV would dump into, and still no sweet diesel engine noise. I pulled the oil filler neck like catman3126 suggested, and as soon as the wife gets home, I'll have her crank the engine while I... -
LB7: 03 LB7 won't start after changing CP3 pump
I'm pretty sure it's the relief. Probably the spring is broken. I'm tearing it back down far enough to take that valve out and check it. I also ordered a low pressure fuel line kit, so I'll start with those two things. Over on the diesel bombers site, there's a few pictures of a simple way of... -

I loosened the high pressure fuel line nut on cylinder 7, cranked over the engine and fuel poured from the fitting. How can I find out how much pressure is in the rail? -
LB7: 03 LB7 won't start after changing CP3 pump
I've been through a few threads about CP3 pumps, air leaks in the fuel system, and injector problems, but I have yet to see anything that can solve this one. I have an 03 LB7 with about 260,000 miles on it. I was getting the typical white smoke at idle problem so I installed all new injectors...
