    on those newer pickups (post 02) the injectors can become a concern over 100k miles... The prior to 02 have mechanical injectors where the injection pump itself controls the injectors. Starting in 2003 the injectors are pressurized through a common rail and computer chips on the injectors themselves control the injection. Injectors with chips in them are a lot more expensive to replace than the older style mechanical ones. The issue with the 24valve motors in the 2nd gen trucks is the injection pump. It's computer controlled and the computer has a stupid high rate of failure, which will at some point leave you stranded. Another weak point of the 98.5-2002 trucks is the APPS or accelerator pedal position sensor. It's the computerized version of a throttle cable. It will also at some point leave you stranded.

    My advice would be to get a 98 12 valve if you're looking for an older cummins. The 98s have the opening rear doors and the 12 valve motor, which has mechanical injectors and a mechanical injection pump called a p7100 pump.

    No matter what second gen pickup you decide on if you go with the older body style first and foremost look on the side of the block on the passenger side towards the rear of the block and look for the casting number. If it says 53, walk away. Or prepare to buy a new block at some point.

    Or buy a duramax, and stock up on tie rod ends
