History: We bought this '73 2.0 last summer. It ran ok at the time, though on cold start-up it would choke if we gave it throttle before it had a chance to warm up for a few minutes. We dropped the drivetrain in the fall to do a bunch of general cleanup on the engine and trans, including:
Today: We finally got everything back together and started the car but it was running really rich, so much so that we could barely keep it running. After we shut it off it wouldn't start again. It would spin fine, but not even a hint of firing. Things we've done:
So first, I think it's so badly flooded that we need to wait a day and/or pull the plugs so that the cylinders dry out. Second, I'm guessing that replacing the hoses fixed a bunch of air leaks, which some PO had compensated for by richening the mixture. I could very well be wrong, just a guess. I've read a good amount and have a basic understanding of the D-jet system, but I'm looking for pointers about where I should start in fixing this. If I'm right about the flooding we should be able to get it started. Then what do we need to start checking to address the rich running? |

Rich - from your previous thread, did you find and connect the CHT (TS2) to the proper sensor? The symptoms are pretty much textbook bad/disconnected CHT. Do you know how to verify that your CHT is good and the connection to the ECU is good?
Other options are blown MPS, fuel pressure too high, stuck fuel injector or CSV. Sorry, I forgot to give you a shout yesterday (IMG:style_emoticons/default/sad.gif) |
