Location of fuel pressure valve on fuel rail buick rendevoues 2002

I don't believe you have one. If it isn't on the fuel rail, I did look at your fuel rail in database, didn't see schrader valve. On these vehicles you tee into the supply line to check fuel pressure. You need fuel gage and proper fittings. Don't take a fuel line loose unless your sure no pressure on the system.

Where is the A/C high pressure switch located for a 2002 Buick Rendezvous? I followed the low and high pressure lines from the compressor to the firewall and no switch. Thanks, DM

The AC refrigerant pressure sensor is located under the air cleaner housing. It can be serviced by putting the vehicle on a lift and removing the air baffle. Then it can be reached from underneath.

2002 Buick LeSabre V-6 Fuel leak but cannot be located.

The fuel lines are steel except for the plastic ends where they need to be flexible for the push-on type connectors. If I am right, those plastic ends pass just under your cabin air intake. Just below that, is a common bend where the steel lines usually rot. If you have high miles they may be baked, or if you had recent engine work they may have been flexed to one side hard enough to split one the three. If one is leaking it is best to replace them all. Don't take chances with gas fumes or leaks. Do it right away!
