Another Rn + 20G, My 'build' Thread


Recommended Posts

The last 20 minutes will take you 2 days. I don't know if that's a saying, but in my case it sure applies.

I got my re-balanced turbo rotating assembly back from GPopShop, and in the process of changing it out I broke the compressor side dynamic sealing ring (the C clip on the thrust waster). I ended up buying a full rebuild, something I should have just done in the beginning, and got the turbo in the car yesterday.

The last thing to do was add coolant, but after the first two gallons I was wondering why the coolant reservoir was still empty. I jumped in the car and found my heater hose connection had come undone and there was 2 gallons on the floor. FML. I called it a night and got an early start at it this morning. I took out the carpets and did a full power wash to get everything out. I guess it needed a full interior detail anyways...

Everything is ready to go, but I'm not getting spark. I found my cam position sensor had a severed wire on the engine bay side so I fixed that. Still no spark. I've been working through my 'Bosch EZK' troubleshooting worksheet and haven't found any problems. I've tried 2 ECUs and looked everything over thoroughly, hopefully I can figure it out tonight.

I'm curious as to how the firewall connector dislodged - I think some one else also had that issue - I've just never seen it or understood how it could just happen.

Did you double check the other connectors to make sure they are connected properly? Crank sensor, etc. I recall someone had the iac and TPS reversed, etc...

Damn, still no luck. I triple checked all connections, although there aren't really that many. I tried to run an XRAM dump from the ECU to see if I could pull any codes; it connects but then drops comms after just a frame or two. Weird, although I've had this problem in cars that were running, so nothing definitive there.

My next move is to test continuity between the ECU and all relevant plugs, not something I'm looking forward to doing, but I don't know what else to try.

Cool, I'll cut that connector off.

I traced all the wire colors and I'm sure everything is plugged into the right connectors, thanks for the suggestion though.


Circuit tested the coil/power stage feed / ground / pulse? knock sensors correctly hooked up? Try another crank sensor? If the car was running before, should n't be anything too nuts...

Do you have any documentation for additional testing?
