Hi.
Recently was gifted a 84 244 DL (engine B23F) with 295k km.
It failed emissions on the NOx test, and I took out the AMM to see if it was clean, not clogged, etc. It looked fine, so I re-installed and now the car won't start. It turns over, and it seems really close to starting but it won't happen. I tried dis-connecting the connector into the AMM to see if sometow it was being tricked by false readings but still it didn't work. Other information is that I had disconnected the oxygen sensor but did not remove it so that I could check the voltage using a meter. I've been disconnecting the battery as I work on the car and then reconnecting it. Could I have messed up the ECU at all? My guess is that somehow the fuel mixture is too lean now, and there isn't enough fuel being injected but I haven't touched the fuel system at all. The other thing is that the car was given to me with about only about an 1/8th of a tank of gas - just above the orange line.
Thanks for any help in advance,
Chris
