1.6TD front seal and back o ring were leaking so replaced them. Have lift pump(had trouble starting before) cranked and cranked finally started but shut off won't idle, started raced engine after a minute or so got it to idle. Idled for 10-15 minutes, tried reving again went back to idle then shut off won't start. Any ideas?
Thanks

I bet some springs fell out of place in there.
-
Which springs? I never had the pump apart. I've replaced the back o-ring on several TDI pumps so I know how much to expose to get the o-ring.
-
Did you take the high pressure pump off? Even if you just pulled it partway off things could've loosened enough.
-
Almost sounds like you replaced the timing cover seals on the "sides" of the pump..
Did you remove the hardlines going to the injectors and replace the o-ring under the pump head?? (Drivers side of the pump)
Are you still using the lift pump?? Any smoke while its running like this?
-
Replaced the mainshaft seal(sprocket end,o-ring inj. line end) yes still use lift pump but have a power line I can disconnect. Some smoke, but I don't have downpipe or exhaust pipe on it yet( straight out of turbo) Idled fine till I revved it, then cut off.

I'd take the top off and see if everything looks good still.
