Sorry that was fuel pressure. I’m guessing the cheap eBay lift pump isn’t pushing the pressure. Ordering a AC delco pump to replace it. As far as boost goes at 70 mph gauge still shows zero boost. So gotta figure that out but already I’m going in the right direction from where I started

So I now have 2 psi according the gauge( seems 3-5 psi low to me) but I just drove 70 mph which I haven’t been able to do since I parked it almost a year ago

Also not my daily driver/ my 6.6 duramax takes that role

You are not wrong. I’ve learned my lesson on the cheap parts. The truck isn’t in horrible shape but it is a old work/ snow plow truck.

So I used a power probe. The lift pump does work when I give it power. There is no power going to the lift pump. So I’m guessing it’s the oil pressure switch. Not sure I want to spend the money on mods so I’m gonna change the ops and see what I have

That makes since. I have already dumped more money into this truck than it’s worth. I trying to get this running right as cheap as possible before the snow starts flying.

Soun

I was just assuming it was a failed lift pump, I installed it 1yr ago it was a cheap after market pump off eBay . I no power didn’t even cross my mind but that’s the first thing I will check

Okay after a long few weeks I’m back at it! Installed a fuel gauge with the leroy diesel fitting. I’ve checked the gauge install and it’s all correct but I’m getting a zero fuel pressure reading along with zero on the boost gauge

Lol it’s 12:30 in the morning but I had to run out to the barn and look, mine definitely has it.

Can someone explain what you mean by “ fish biting0?

I want to say they were Bosch but I’m not sure that was a year ago. I do know the problem was before the injectors and there was zero change after the new ones were installed.

Good info! When I purchased the truck I also received a full lifetime maintenance record hand written by the previous owner. According to the record the injection pump was replaced or rebuilt about 8 years ago

So much help and advice in a short period of time! I’m liking this forum already . I just ordered the hook ups from Leroy diesel .I will go down these list and check all items , probably be next week sometime being that it’s fair demo derby season and I have some destruction to inflict. I’m sure...

Good to know about the glow plug tool! It smells like fuel, the air filter was replaced and I have not found any vac leaks as of now. I will attempt to make a video this weekend. I’m not getting any codes
