      I know this is on here somewhere and would greatly appreciate some guidance toward the answer. We have an 1997 OBD2 vr, with all CE2 wiring. I can not get the fuel pump to prime with the ignition. It will get power if I pull the relay and jump it. Obviously I am missing something but for the life of me can't figure it out. Admittedly I am a novice at car wiring, but I would greatly appreciate some guidance.

      Thanks in Adavance.

      Are you talking prestart prime or what ???? Or no fuel when cranking ? Make sure you have the red wire jumper for 30 to 30b ... BTW what harness did u get a Passat ? Jetta ? GTI ?

      I had he same exact issue. Make sure you go over all the wiring how tos and FAQ 30 and 30b are jumped. Then test your crank position sensor. The crank sensor was my issues a couple of other people on here

      My bad, In my haste I forgot to mention it was a 97 passat harness that I had Matt from Eurokraft remove all of the bs we aren't running. air pump, emissions,etc. there is no prime or fuel while cranking. I have 30 to 30B jumped.

      I have a vague recollection that obd2 doesn't prime with key on. You get fuel on cranking?

      No it doesn't get fuel while cranking. I have read that in most cases you need to make a jump for the alarm bypass. That being said the alarm was never installed, but does it still need a jumper on the fuse block somewhere to bypass it. If so, do you recall which circuits need the jumper wire?

      Obd2 does not prime.

      Alarm only bypasses starter.

      Ben nailed it, alarm only bypasses the starter. Can you scan it for codes?

      Is obd port wired or no scanner? You can usually borrow from auto parts store.

      No port, unfortunately. I check the harness at the ecu and I am getting power to pin 68. Is that correct? I am going to check all of the grounds today. It does not appear that there is a ground from the engine. Its supposed to come off the starter correct?

      Wire up a port. Do you hear throttle adapt?

      Starter is power only. Ground to bolts connecting trans to motor.

      The good news, Found a bad ground and now she runs. The bad news is she won't hold an idle and has a nasty backfire. I appreciate everyone's assistance. More to come. Thanks again boys.
