How to fix the cruz control on my 2006 Cadillac srx 3.6L

Using a factory or professional type scan tool to diagnose this . checking of DTC'S - diagnostic trouble codes would be the first step , finding info on how the cruise control works , what componets are involved . Do you know what a wiring diagram is , how to read one ? How to do electrical testing with a DVOM - digital volt ohm meter ?
free wiring diagrams here Enter your vehicle info. Year , make , model an engine size . Under system click on engine , under subsystem click on speed controls ! Then click the search button ,then click the blue link . Looking at the speed control diagram you will see the IGN 1 relay supply's B+ voltage to the cruise control switch ,which is a input to the ECM - engine computer . From there it is all done internally via the computers . Your best bet mite be to have a qualified repair shop check it out .

ECM fuse keeps popping and fuel system don't work

There should be two ECM fuses. Number one powers the injectors and some of the solenoids along with the ECM. Number two or B powers the fuel pump relay and the rest of the ECM including the sensors that provide data to the ECM. Both are 10amp circuits.
You may need to get a shop manual to have the wiring diagrams to troubleshoot the circuits.

I need a wiring diagram for my jeep. I need to trace things out so it will run.

Honestly the best advise I can give you is pick up a Chiltons or Haynes manual for your Jeep. It will have complete wiring diagrams, troubleshooting, and lots of helpful info on fixing the Jeep. You will thank me later because I guarantee this isn't your last wiring problem in the Jeep.
