2006 Buick Rendezvous won't start

Did you ever get it fixed? I am having the same problems. Anything would help

I also have a 2006 buick rendezvous

Camshaft position sensor

I changed the MAF, cam position sensor, throttle position sensor, purge valve solenoid, idle air control, fuel filter, plugs, wires and fuel pump and still have a no start. Got fuel to the rail and spark but won’t start

Don't know if you ever got this answered but it could be the security system. It won't tell you with a regular scan tool but I have a Thinkdiag (like 100 bucks) and it toId me that my security system has shut the fuel off. So you won't get a check engine light and you won't see any codes for it with your normal scanner...I don't have an answer for the issue yet, just found it out. Hope this helps someone

Crank position sensor. Mine was covered in oil so it couldn't read the crank when I turned the key. So the fuel pump didn't engage. Hope that helps.

check fuel pump fuse or the electrodes in the key could have broken check fuel rail pressure if its low bad new fuel pump. replace.
