    I fell into the internet ocean of what appears to be scattered and mostly old or useless information on which glow plugs to install in my 2006 KJ CRD these days. 7v Ceramic, not any more, 5v Steel with new module ?, 7v Etechno, (they dont even exist)

    I am getting a P1261 which i understand to be a #1 glow plug issue. So what glow plugs should I use?

    Thank you,

    The debate has stopped raging on glowplugs. Tips on the original 7 volt ceramic glowplugs were breaking off in the combustion chamber and getting slapped around by valves destroying engines. Dealer move was to replace them with 5 volt metal glowplugs with a 5 volt controller and dealer reprogram fee. Many went with 7 volt metal glowplugs to skip the new 5 volt controller and dealer experien$e.

    The 7 volt metal glowplugs didn't work well in cold climates so some adventurous folks went to 5 volt metal glowplugs without the 5 volt controller or dealer reprogram which seems to work well for many although not as well as the original ceramic glowplugs with the optional engine destruction feature.

    So. If you live in a warm climate I can make you a deal on my brand new, never installed 7 volt metal glowplugs. If you live in a cold place you'll probably want the 5 volt metal plugs. If you live in a very cold place Sasquatch (I think) makes a grid heater that's installed between the intercooler output and intake manifold. If you live in an extremely cold place you can install a Webasco diesel preheater which preheats the coolant and block.

    LOSTJEEPS has the most info on the 2.8 CRD engine and its' foibles.

    P1261 code... Maybe low power to #1 cylinder glowplug. Check the power harness connecter on your #1 glowplug and condition of the wire going from the #1 glowplug and #2 glowplug. Or there might be a problem with the #1 glowplug itself.

    The wiring harness energises all four glowplugs at the same time. The harness goes to #4 plug and then links to #3, #2, and #1at the end.

    So I contacted the dealer near me, to get an idea what glow plugs would cost. He quoted $84 but wasn't sure if that was 1 or all 4, so he created an order to bring them into the dealership to determine. Still waiting for the call back will post when I get the info.

    For anyone getting the P1261 I recommend going to the below thread link. The section on checking impedance at the Regulator connection was super simple and confirmed for me the following:

    Glow plug 4 - 2.2 Ohms
    Glow Plug 3 - 2.2 Ohms
    Glow plug 2 - 2.1 Ohms
    Glow Plug 1 - 5.9 Mega Ohms - BINGO the reason for my P1261.

    Here is an excellent thread with pictures. Nice Job to the Author.

    $84.00 Would be for one glowplug. I paid $120.00 each for my metal 7v plugs which aren't going in my jeep and about $100.00 each for the 5v plugs.

    Check to see that the dealer isn't selling you a ceramic glowplug. I'll just give you one of them if that's what you're going to install. They're a known problem that should be avoided.
