On first cold start (Houston Metro Area) got code P1261, P1263, P1265, P1267.

How do I check Bosch Module. I think it is the one behind the battery. I need a diagram or the page in the service manual that show the location as in the jeep.

I suggest you read Sir Sam's Nood guide :SOMBRERO:

There you'll find where you can down load the fsm and have all the pages :BINGO:

So i checked the resistance (using a fluke meter) of the glow plugs from the connector - Each had a omh reading above 200

>200 is dead - .5 to 1 is good (and a lot of meters won't read that low)

although I don't know that I would try to replace them until the metallic versions are available.

when I was having glow plug problems I plugged in the block heater overnight - don't need the glow plugs and you get instant heat in the morning.

pretty sure it'll still be Bosch - however the limiting factor is that Jeep has to tweak the engine controller - it'll use a different voltage from the ceramic versions.
