Hi, I am new here. But I have been reading many great forums on this site without registering. Thanks everyone for contributing great ideas and resources through this website!
I am having some problem with my injection pump. It all started as diesel leaking at the pump. Then I found the videos and seal kits online and decided to replace the seals myself. I am not a mechanic but I have been doing maintenance on my parents and relatives' cars for some years, so I thought it is something I can do. Well, it kind of went well, that I replaced all three seals without much of a problem (the seals that were taught replacing in the video, you know what I am talking about, right?
) I assembled the pump, and started cranking the engine using a wrench to see if the pump would freeze up, without knowing that the nut I used to crank the engine is actually the 22mm pump timing nut . I used a marker to make some marks around the 22mm nut and the pulley, and started reverse cracking the engine to see if the nut would move to other position or not, and it did not. Thinking that the timing should still be fine, I tried to start the car. After a few tries without success, and the Vaccom tool says 30-40 mg/st reading, I was in a panic... I thought the pump's electronic connector may not have good connection because some of the diesel fuel went to the male side of the connector. To clean the diesel fuel out, I used brake cleaner and spray into the male side of the connector, and wiped clean with some cotton swabs. I guess I shouldn't have done this, because right now, the car starts but rev to 3000+ rpm at idle, and the Vaccom says 0 mg/st all the time, with lots of smog coming out of the tail pipe!! The engine code also says that the QA upper limit reached!! I cleared the code and the code reappeared almost immediately after I cleared it. In the past couple days without working on the car, I can tell that the pump is still leaking a little bit of diesel.
I really don't know what to do now. The problems just seem to escalate overtime, and every time I work on it. I really need help.
Many thanks!!
