I've got the 300d home and found that the transmission needs a rebuild as expected, but also that I don't have boost.
What I know: - Tracing vacuum diagrams I found that the EGR and recirc flap control have already been BB'ed at the vacuum source - Turbo seems to turn freely. Some oil in the intake but nothing big. - Putting pressure gauge in line between intake and ALDA see about 3 PSI, max. - With pressure to ALDA on acceleration (5-10 PSI) there isn't a jump in power from expected fuel enrichment - Putting a line direct from intake to ALDA doesn't help (something that worked on another car) - Applying pressure to the ALDA shows minimal leakage - EGR has a plate covering the port - Turbo overpressure rod moves freely - Car doe not appear to have a cat/trap in the exhaust system - OVP is OK This car has a LOT more going on than the last car I had a no-boost problem with. On that, a 300sdl, jumping a failed switchover valve fixed it. This car has at least 2 more vacuum/pressure control pots, a mass air flow sensor, and a boost sensor near the battery. I'm not familiar with any of these, and the service CD's are at best spotty with coverage. My questions: - With the added systems is there an electrical element added to the injection pump that would prevent enrichment when jumpering the intake to ALDA? - Does anyone have a used Garrett TB025 turbo if mine proves bad - Anywhere else I should be looking? Thanks!
