Hello everyone, This is my first post on the forum, so thanks for any help you can give me. I have an ISUZU P75 5.2L with a semi-automatic gearbox, which started to fail some time ago. The most common failure is that when changing from 5th gear to 6th, the vehicle collapses and does not engage the gear and remains in 5th gear without being able to go down or up.

Hello, I have a 1998 Isuzu NPR with 3.9 turbo diesel engine 4BD2T. For the last 10 days I've been having problem starting it. It cranks fine but it doesn't start. There is white smoke From the exhaust while cranking . Few days ago I started it with a starting fluid and it started and ran fine on it's own. Drove it for 15 miles until it fully warmed up and also did few stops and starts of the engine (while hot it starts fine) but if I leave it for an hour or more it goes back to no start just... 1998 Isuzu NPR 3.9 turbo diesel crank no start ..read more

Greetings all, I am looking for a small explanation of how the diesel gets sent from the fuel tank to the engine on a 2020-2023 Izuzu FTR.

I can press the button on dash with same exhaust symbol but light doesn’t turn off. Seeing... Question regarding exhaust brake ..read more
