1. Be sure the battery is good. 2. If battery is good you probably have a passlock problem, which usually means the ignition key cylinder or ignition switch is faulty. 3.

Bugger....Just my luck, as the general feeling was ignition switch, spent the $250 & fitted new, drove ok for about 45 minutes then the lights started up again, Ignition, Passlock, Service....just as before.... Where next anyone.... Many Thanks anyway

He said switch not lock, they are two separate parts. It does sound like a bad ignition switch. Get a hold of a volt meter and while it is acting up check the voltage at your fuses. If you find some showing a significantly lower number than the rest the switch is by far the most likely candidate.

Ok... So, I am really hoping someone may have some sort of answer for me here. I am pretty much more than angry with my car right now. My freaking car will not start when it is cold but it will if it is hot. I have within the last 3 weeks replaced my battery, replaced old looking wires, replaced my dang starter... what else will make a car have problems when it is cold? And by cold I do not mean freezing. I live in California so it is around...

Yeah I don't have a scan tool so I wish I did have one. Just thought i'd pick everyone's brains for some idea's. And to what I could also do myself. Guess i'll just wait till next week when we bring the car back in. I tell ya though...I like the car. Tired of the problems. I miss my 83 monte carlo, 81 trans-am. And I have to admit with all the problems i've had..I have so much more respect for ford mustangs....

It's likey a passlock issue....is the security light on solid?

Re: 03 Monte 3400 Emmisions light at elevated RPM's HELP. I had an 03 Monte that had similar problems... It was traced back to a damaged Catalytic converter that I messed up while driving over the snowbank at the end of my driveway that the snow plows left...The snow looked soft but was rock hard...My front tires were off the ground...I didnt mind to much because it gave me a reason to put on a new cat back dual exhaust...
