I bought this truck in Dec 2008 with 193,000 miles on it. At 185,000 it had a new long block, heads, injectors, turbo, glow plugs, and injection pump over $7,000.00 of work I have the receipts. The truck was a back-up truck in a small fleet that pulled a 30ft trailer the owner used for his insulation business. It looks good and runs great plus it was only 4500.00! But recently it has been starting hard. It used to fire right up after the WTS light goes out even out in the cold (not to cold down here 40 miles from TX). Know I hold the pedal to the floor and it takes several seconds for it to start which is followed by white smoke then it clears up and runs like a scaulded dog. The first start after it sits over night takes the longest. Its nice and hot down here 95-100's. And the gow plugs seem to be cycling correctly I have replaced the glowplug relay, and the lift pump but still have the problem. Sometimes it will throw a DTC 36, I'll clear it with my scanner and it may not do it for a month. This is my 1st diesel and I love it, but I'm still learning so any help would be appreciated. This is an Awsome site with great folks that have a wealth of knowledge. Thanks in advance and sorry this is so long
