Hi all,
My 2003 HDJ101 Sahara (AU domestic market version) is acting up. It would start and act normally when cold, no starting issue at all. However, the engine will be unable to start after a long drive and things gets hot. The symptoms are really weird, after things get really hot and I kill the engine and immediately re start it the engine would re start in a single crank with no problem at all, but if I leave the engine off for a few minutes it will refuse to start until after 45 mins or so (when things start to cool down), the engine would turn over normally but unable to come alive.
I have had this problem for a while, it was much worse before with the engine spontaneously stall when hot and refuse to restart until after 1.5-2hrs. I initially was able to fix it by cutting the plugs on the spill valve and made direct soldered connection bypassing the spring loaded plugs on the spill valve directly to the EDU wire. Turned out after a month the problem re appears. I have replaced all fuel feed and return hoses, fuel filter mount/fuel primer pump, purged the fueling system with Liqui Moly diesel purge yet the strange problem persist. I have consulted with 2 specialists and both pointed their fingers on my Injection Pump......I initially refused to believe them because it’s too easy to replace the most expensive part and the engine is revving fantastic and there were plenty of power, but now I begin to doubt myself. Lately I could feel the engine losing a bit of power and not as lively when hot and becomes lively again when cool, a sign of worn Injection Pump? Can anybody advise me to which direction I should look at before biting the bullet and buy a new and very expensive Injection Pump?
thanks in advance!!
