Thank you. Can you send me the fuse number that is blowing?

Fuse 25

Automotive Expert
Thank you. One moment while I gather some information
Automotive Expert
OK thank you for your patience. This fuse powers up the auto shut down really. You're sure that you have unplugged the oxygen sensors and the alternator and the problem remains? Does this fuse blow right away when you turn the key on or start the engine or does it blow intermittently while driving?

Cranks but no start soon as the key is turned fuse blowsFuse 14 responsible for asd relay is not there could that cause the crank no start and fuse blown issue
Automotive Expert
Is this fuse 14 inside the vehicle or under the hood?

Under hood
Automotive Expert
Yes, that was for the automatic shut down relay and for the powertrain control module.
Automotive Expert
Yes if that she was missing you need to install a new fuse and retest the system. I have a feeling based on what you're telling me the engine will start and run. If you install a new fuse and it blows right away you need to check that circuit from the fuse to the ASD relay to the powertrain control module to determine where it is shorted. Fix or re-run the wire as needed. It has been a pleasure working with you so far. Keep in mind this is a “starting point”. We can always continue as needed at a later date or at any time. Feel free to run some tests and reply back for further assistance as needed. Glad I can help. Please let me know if you have any further questions. Thanks and have a great day!

I was incorrect fuse 14 is there
Automotive Expert

Ill disconnect the alternator and replace fuse and give it another start if it works then its the alternator or fusible link ?
Automotive Expert
So fuse 14 is there and is working like it should correct? And the fuse 25 is the one that is blowing when trying to start the engine correct?

Automotive Expert
Fuse 24 powers up the PCM. Either the PCM is bad or the wiring going to the PCM is shorted. Looks like it is the orange wires with dark green stripe that runs between this fuse number 25 and the PCM. Click on the link below for a wiring diagram of this circuit.

Thank you for the reply with codes. Right now I don't see how it is related to the fuse that is blowing. However you can certainly fix the wiring issue first causing this fuse to blow and then retest the system.

All wires under power distribution box look good unplugged all mechanical devices on that circuit fuse 25 cant find any questionable wires that short to ground still soon as i turn key to on without cranking fuse blows
Automotive Expert
Can you speak on the phone?

Still not sure what you need?
