Auto shutdown relay and fuel pump relay are by the battery under a cover.

the auto shut down relay is not like a fuse that can shut the engine off the name it has actually has not much to do with its function.. the relay is controlled by the computer .. its main function is to stop run-on and turns off o2 heaters power to coil and injectors if you had the key in the run position and engine not running your battery would dies faster than a drive in movie.. but anyway if your stalling and think its the relay failing just swap it with another one that looks the same from the PDC.. what you may have is a bad fuel pump or even a crank sensor have you had it scanned for codes? sometimes but not always you may have a code for lean upstream o2 if the pump is failing but not always.. and for the crank sensor you may have a crank shaft position sensor performance or cam/crank sensor code ..

I changed all the parts I mentioned and finally I decided to try the crank shaft sensor and if that didn't work I was going to replace the cam shaft sensor. Luckily the crank shaft sensor worked but only after I replaced all the other parts. But at least now it finally started.

Thsank you.

It could be a number of things. These include: faulty coil wire, bad alternator, bad torque converter, bad computer, the ignition relay is giving out, a dirty and stuck idle control valve. It should be one of these problems. How to tell which one it is is to follow a systematic approach and test each indiviaul item/circuit.

Sounds like you have no readable engine rpm. Check your crank or cam sensor.
