1994 Buick Park Ave won't start
The security system will keep it from turning over on that model. You need to try a 30 minute theft learn. Follow these instructions closely. Try to start the car, then leave the key on for 10 min. Turn the key off, 2 or 3 seconds. Turn the key back on, do not try to start the car this time, leave the key on for 10 min. Turn the key off again, turn it back to run, do not try to start it again, leave it for 10 more minutes. Then turn it off, and then try to crank it. If it is a security problem and it is not the ignition damaged it will crank. Good Luck. Mike From Texas.
I have a 2003 Buick Rendezvous and I am trying to locate a schematic for c305 connector so my shop can see it and determine if they want to try to bypass the connector and hardwire the wires.
This is some food for thought. The c305 connector carries the wiring for three major subsystems in your Rendezvous' overall electrical system, the fuel pump, evaporation system and all-wheel-drive. Though this part has been subject to water leakage due to the design of the vehicle, I believe it would be a much better idea to replace the terminals within the connector rather than replacing the entire device and hard-wiring the systems.
For one thing, it is entirely possible that hard-wiring could pose problems for your Rendezvous' diagnostic system because the rewiring might start throwing incorrect codes to a diagnostic reader because of a lost connection.
For another, it is also entirely possible that when you remove the c305 connector that the new hard-wired connection may not lay correctly and it might become a conduit for leakage. Indeed, that is one of the ongoing problems with the c305 connector. There have been a couple of service bulletins issued for various Buick models built in the 2003-2005 timeframe that cover the connector. The bulletins deal c305 issues such as corrosion caused by the design issue.
My suggestion -- and remember it is only my suggestion -- would be to replace the terminals within c305 and after it was all cleaned up and secure, pot it up with non-conductive, waterproof grease so that any potential leakage would no longer be an issue.
If you still want to replace the connector, I can forward the diagrams you are looking for.
How do i straight wire the c305 connector
Please send me these diagrams! You would be my savior today if you see this man! Cannot figure out where kn earth this orange wire goes, had to change my c305 on my 2007 buick rendezvous and there's and orange and light blue wire left with nothing the same color to hook to on the bottom side(that goes to tank)
