Default no power to fuel pump sn95

There is no power getting to the fuel pump, inertia switch, or the ccrm. At first I jumped the ccrm and put power to the wire that goes to the pump and the pump turned on. So i thought the fuel pump relay was bad in the ccrm. So I changed that and it still does not turn on. The EFC fuse and the fuel pump fuse is also good. So is it the pcm not sending power to the ccrm?

I also noticed that there is a clicking noise when I turn the ignition on. The sound comes from the thing that is under the ccrm at the bottom of the car directly below the ccrm. It is also connected to the ccrm. Does anyone know what that is?

notice all the brake lines going into that module.... its the ABS.

your gonna have to check to see if your getting power out of the ECM... but its more likely that you have a CCRM issue

Here is a quick way to check the FP portion of the CCRM...... check the VIP connector layout below, place a jumper wire between the FP trigger terminal and a ground, turn IGN ON.....if the FP doesn't activate, make sure the internal FP relay in the CCRM is working by disconnecting and reconnecting the grounded wire..... the FP relay should be heard clicking....

alright I will check the power coming from the pcm. If its not that then I will use the self test for the fuel pump relay. Im hoping its not that because I just bought this one on ebay and put it on. The guy said it was good

Don't neglect checking your wires, my last electrical problem was with a faulty wire going from the inertia switch to the pump. Sometimes it's improbable but not impossible.
