I dunno, sounds like I'm probably just going to have to drop the car off at the dealership to have them troubleshoot it. I don't have a good place to do it, or the time, especially now that there is snow on the ground. Hopefully it won't cost too much, lol

It's a 2000

The fuel pump relay is inConstant Control Module (behind the coolant reservoir) and the fuse is in the Batt junction block 20 amp fuse......

Batt juction block is on the drivers side ,near strut and master cylinder.

How accessible is the CCRM? Are there individual relays or is it one big unit? I checked the fuel pump fuse, it was fine. I'm not really sure where the problem could be at this point except for there...the pump still isn't coming on at all. Things left to check I guess are voltage at the inertia switch, but what about the CCRM? Is there anyting else?

It should be all one unit...its not individual relays.....I've replaced several on the oldtaraus'sLOL....most for cooling fans not coming on...Did you have power at the fuse,,or did it look good...Yes,,,for sure,,,check for power to the inertia switch on both sides(wires) .turning the key on should get you a 2 to 3 second on= off ..and cranking ,,it should stay lit...if so,,you just eliminated the possibly CCRM and the fuse...By the way ,,,,(key in the run position),,,the Theft light isnt flashing is it?

Voltage is good at the fuse. I'm going to check the voltage on pin 11 on the CCRM, that's suppose to represent power coming from the fuse. If that is good, I will check power at the inertia switch.

Does the CCRM look like a rectangular box with a connection on the top with a bolt holding it on, very close to the firewall on the passenger fender? Let me know if that sounds right...

I'm going to try and get someone to turn the key while I test the inertia switch. I don't think the theft light is blinking while turning the key. What would that suggest?

I tried testing the CCRM, but I'm really not sure I'm testing the right thing, it doesn't look like what the book shows.

I'm having the exact same problem, but my theft light is flashing. Is it PATSrelated?
