1999 PSD Hard to Start

[plumberdude]

My 1999 PSD w/72000 miles is hard to start when cold. Installed new GPR and one GP has high resistence. The batteries are originals. Could they be the problem?

Your starting system could well be the problem. I replaced my GPR, the glow plug harnesses, and the glow plugs, with little success. Kept checking my cables/batteries/starter, and it wasn't until the starter and one of the batteries failed that I got the beast to start in the cold without plugging it in at night.

Make sure you go through the simple stuff too, like cleaning the battery terminals/cables. Before my battery/starter change, there was a slight drag during starting that I didn't really notice. Not until I replaced the battery that died and the starter that failed did I realize how quickly the truck should turn over. Made a huge difference. Starts in the mornings after very low overnight temps, without ever plugging it in. Oh, my truck has almost 200,000 on it.

Thanks for the info....New batteries tomorrow. When the dealership did a voltage check on them they said they were OK but that was without load. Batteries wear down after 6 times of trying to start. If I plug it in it will start fine. The batteries are the original bateeries when I bought the truck new
in "99" got 10 years out of them.
