    Default What type of batteries

    I have had to jump start my truck a couple of times recently. If it turns out I need new batteries, what kind would you guys recommend? Thanks.

    I've had good luck with Napa batteries. Last long and crank good. Just my two cents
    I have a 1997 horton 4X4 ambulance converted into a motor home. New hot glow plugs, remote PMD and cooler and air induction kit. New duramax fan and 180 degree thermostates. I also own two 99 suburbans.

    I bought my truck with NAPA batteries and the seem to always have some warrant left when they go out. They start my truck, so I have to be happy with that.

    Thanks for the replies. I will check into the NAPA batteries. I like the Optimas but they are expensive. I don't use the truck to make a living anymore but I do drive it quite a bit and use it for a part time business.

    I am hoping that I don't have to replace the batteries. When I jump the batteries to 2 other vehicles, it is still hard to start so I bought a new pmd harness to replace the one that runs to the bumper hole pmd location. I plan to replace that this week. I also tightened up a battery cable. One of the 4 screws that hold the pmd to the fsd heat sync has a rounded out head and I am not sure that it is tightened properly so that is going to be replaced as well.

    I have another question. I have an extra, never used pmd. I bought it 2-3 years ago, along with a new wiring harness. When I put the new harness on the old bumper hole pmd, it started working fine so I kept the new pmd for a spare. My question is this: Is it just heat that wears out the pmd or do they go bad after years of use, even when in the bumper hole?

    Thanks for the help.

    Like any electronic device, a pmd may last "forever" or fail anytime, but heat kills them.

    Thanks. I put the new harness on and saw no improvement. I will get the new pmd installed this weekend and post the result.

    Regarding batteries, my current Optima batteries are 5 years old. I understand that the quality of new Optimas leaves much to be desired. If the new pmd works, I am leaning toward Interstate batteries. If the pmd does not work, I am leaning toward torching the truck. JK

    Ok, I'm sure this is a stupid question but I can't remember. When I put a new pmd on the heat sync, do I remove the black plastic diamond-shaped covers from the underside or leave them on?

    thanks

    Default Now what? Fuel Filter?

    After looking online, I went ahead and took the black plastic covers off the pmd before putting it on. I also replaced the white dot and red dot egr doo-hickeys. After charging the batteries, it cranks fine but still will not start.

    Could it be the fuel filter? I am overdue for a new one.
