Fuel filter changed - no water in it. - no heater or water sensor either.

Be in touch.

There is a heater/water sensor ....its the plug you had to remove refit that plugs into the base of the filter when you changed it.. Its a bayonet fitting. It will run without it so if you did not fit it, its probably hanging down on its wire somewhere beneath the filter....seen that done several times!

There is also a black knirled plastic water tap on the back of the filter to drain any water. Gently release it when running to blow any water out.

My Jeep usually takes a few attempts to get the codes. I get the best results with a slow and deliberate turn. Turn it far enough for the dash lights to come on but NOT far enough to crank and leave it on on the third "on". If the word DONE comes up then there are no faults! Just keep trying til you get done or the codes.

Hi All,
My thanks for your comments. The hard start is now solved. I pulled a glowplug, saw a blob of carbon around the tip (like a match head). When this was removed and cleaned with EGR cleaner and checked for heating ability the car now starts fine. I have cleaned the other glow plugs. In this case the glowplugs would test OK electrically, but not present a red hot tip to the fuel.

This all makes sense. However The glow times still don't relate to the coolant temperature (workshop manual table). My glow time(lamp) for 5 deg C is only 3 secs, which seems a bit ridiculous especially if the heat has to get through some carbon. Any other comments are welcome

Still learning,

P.Diamond

Excessive carbon build up in a diesel engine can be caused by poor quality fuel or oil in the system. Check your intercooler pipes for oil residue.

.....or vent your crank case breather to the atmosphere like me to avoid oil in the pipes and intercooler and intake as well as it blocking the egr valve. Sod the polar bears!
