Hard to Start 1.6 EcoTD - Second Time Usually ???

[vwautotech]

1991 Jetta EcoDiesel

Cold start, usually no problem. Second try, usually all the time. Car has never left me stranded. I've replaced the air filter, fuel filter, timing belt, added a can of diesel purge. I'm thinking the problem may be the injection pump timing, bad ground wire, or something fuel related.

Please post your comments.  :shock:
