So, after a long time of looking I have resorted to pleading for help. I acquired a early 99 Jetta Tdi. Injection pump leaked. I took it out, replaced the seals, reinstalled and it wouldn’t start. By the look of the pump it seemed to have been tampered with previously. I had done the standard timing procedure, tdc on the flywheel, locked cam with lobes up on cylinder one, pinned pump, and no success. I examined the pump and came to the conclusion that the pump was injecting on the pistons way down. So, the pulley on the pump shaft had been moved. I checked the plunger shaft with a dial indicator, oriented the pump to inject on cylinder one compression stroke, reinstalled pulley, installed pump, set the timing pulley to neutral on the adjustment bolts, and BOOM! Engine started right up.
However...
The car smokes white diesel like crazy. The QA is full right, for full injection, thanks hammermod , and will not start or run for that matter, if I move it toward the belt side of the pump.
I have VCDS lite and when in basic settings and pull up the timing graph, I select the proper engine, my graphing bounces between 38 and 255 on my timing. It bounces between on the graph, and off the graph.
So, why won’t my car run when I lean it out? It’s obviously getting too much fuel due to the smoke. Because I can’t read the graph, I can’t really adjust the timing pulley.
Also, why can’t I read it on the graph? I have tried so many things to get it to read and I just can’t get it to do so.
I have tried advancing and retarding the timing pulley and QA via hammer mod in hopes it might pick up on my computer. The engine either starts after 15 seconds of cranking, or 2 seconds, and when I adjust the QA while running, the engine just dies.
I am at the end of my rope here. I found a thread where the guy had all the same problems but was fixed by plugging in his commencement valve and hammer mod. Mine is plugged in and my hammer mod does diddly.
Any tips? Ideas?
