06 LBZ P0087 Headache
thanks guys! I just spoke a local diesel shop, going to get a estimate to have them swap out the CP3. They also want to look at flow rates first and a few other things before jumping to a CP3. Definitely keep everyone posted. Also, I really do appreciate the guidance and advice from the forum. -

06 LBZ P0087 Headache
You guys think putting in a new CP3 and flashing the ECM? At that point, what else is there? The entire fuel system is new. -

06 LBZ P0087 Headache
I bought the truck with EFI Live already installed and I don't have the EFI Live tool to adjust it. It never came with the truck. Any thoughts on how to get that done? I am almost at the point of doing the CP3 and flashing the ECM back to stock. -

06 LBZ P0087 Headache
Well the FPR might not be the ultimate fix. Wife was driving the truck home last night and was starting an uphill back road to the house doing about 20-25 mph (in the stock tune - don't really use the tunes on the truck) and DTC - P0087 popped up. It appears the code pops up randomly. At this... -

I want to start off by saying THANK YOU to all on the forum and provided input and things to look for. I have checked over everything and that seems to check the box of potential issues was the FPR! I bought a new Bosch FPR and installed it. Truck runs really good. I am hoping this is it... -

06 LBZ P0087 Headache
When I turn the key to on, the lift pump starts up. It seems that it takes a minute to prime itself, then the fuel filter head. I am gonna see how it starts this afternoon since it has been sitting for 18 hours. It was odd, because right before all of this, I had a P0088 code....which didn't... -

06 LBZ P0087 Headache
I have a fuel pressure gauge on the lift pump and it verifies at 10 PSI. The odd thing was, I just drove the truck an hour earlier and parked it for baseball practice. When I left, I turned the key waited 3-5 seconds, and tried to start it....just cranked over. I did this twice. When I popped... -

06 LBZ P0087 Headache
Wanted to provide an update and additional issues I need advice on. There was a lot of recommendations to replace the CP3. I spoke to a few diesel shops and they said injectors before CP3. I went with new injectors. The P0087 hasn't come back on since and the truck runs good. Just recently... -

06 LBZ P0087 Headache
I haven't had the time to really do a return test, but managed to have the time to do an injector cleaning (smh) with the AcDelco 10-3015 stuff. It seemed to help. The worst injectors I had were #1 and #2 and they sat at -3. once complete #1 was -1 and #2 was -2. All other cylinders were... -

Was narrowing it down to Injectors Direct (as they are 45 min from my house) or Industrial Injection. Any recommendations? -

I know I am probably doing a couple things ass backwards, but that is on me. I went ahead and replaced the FPR and still have the same issue. Definitely going to do a return test this weekend. My question is, what is everyone's thoughts on a reman CP3? Thanks again guys for all the... -

I can do that. What values should I be looking for. I have seen online less then 100 ml over 15 seconds? Is that correct? thanks -

06 LBZ P0087 Headache
Lift pump (when hooked up, right now its unplugged and the fuel lines are capped) was providing 8-10PSI at all times. It hit FASS recommended PSI Rating. I looked over all the electrical connections when installing the lift pump and triple checked during this time. I would be furious if there... -

06 LBZ P0087 Headache
Thanks for the advice. I did install a PPE Race Plug. The old FRPV seemed fine but I was just checking the boxes and eliminating items. I have been kicking the idea of a new FPR over a new CP3 at this point. -

06 LBZ P0087 Headache
We did command max fuel, everything lined up as it should. I did reach out to a local diesel shop today and after explaining my situation, he immediately said CP3. I do have a question, when a pump is wearing out or going weak, is cavitation taking place ? -

Hey guys, brand new to the forum and new to the website. I have been searching all forums for guidance and things to look into before I registered and started a post. I would like to thank you all in advance. As many others, I am having issues with the P0087 Code on my LBZ and I am at a loss...
