dealership claims injector pump timing failure but have good lift pump pressure
I have an 02 2500 Diesel 5.9 24 valve, manual tranny, 2nd gen body style truck with 66k. My symptoms have been: I crank it up in the morning and get white smoke with poor acceleration for about a mile. Then it clears up and the engine runs normal the rest of the day. During poor acceleration I can push the petal to the floor - there is no difference, the truck slowly accelerates. This does not happen every time I crank. I was given advice to lubricate the waste gate since my lift pump pressure gauge was not indicating any pressure failure. I did do this and it did seem to clear up my problem initially. After about a month, the problem kept reoccurring. I even put nut buster on it to no avail. In the process, I washed the engine compartment and after cranking up, I had terrible rumbling from the engine which vibrated the entire truck. I was blowing a massive amount of white smoke out the exhaust. I finally took the waste gate assembly apart and checked it - it was opening without problems. I put it all back together, I drove it and had no incidents that night. The next day I had the rumbling again and major smoke. I decided that I had to break down and take it to Dodge. I made an appointment to go the Dodge today. Ironically it cranked fine and drove great all the way to the dealership. They put it on the computer, and they claim that it is indicating a code which is injector pump timing failure....and so they say my lift pump is not putting out enough flow. They say it needs to be replaced inside the fuel tank and the injector pump must be replaced too. I told them that I have good lift pump pressure . They claimed up and down that despite having a fuel pressure gauge, that meant nothing - it was all about the flow. How can you have flow without pressure? I have never had low lift pump pressure. I hang out at around 12 when I drive, 13 while idling, about 11 on acceleration. My fuel mileage remains the same as it has always been. I don't trust what they are telling me. They want me to fork over $4000.00 to do the repairs they indicate. I asked them if it could possibly be the breather, but they blew me off. Some of my friends who have diesels are mentioning it might be the turbo. Unfortunately there is no other Dodge dealer in this town to go and get a second opinion. I don't have a code indicator on my truck, so there is no way for me to check if indeed they are telling me a correct code. The fact that a salesman told me that they are getting rid of their o8's at invoice minus rebates which amounted to about 12,000$ off - so most who were getting major repairs were just opting to trade in - and thay anyone who got their old Dodges repaired were making a bad financial decision - does not instill confidence in me that they don't just want to pump up maintenance costs to cover slow sales and/or force a trade in on major repairs. Can anyone help me? I am pretty much stranded here in Montrose, CO until I get a handle on this and get whatever is wrong fixed.
