2007 Nissan Titan won't start. It cranks strong, but not

Customer Question

2007 Nissan Titan won't start. It cranks strong, but not starting. I bought it from insurance auction with damage to front R fender and headlight. Fusebox and ECU were not damaged. I changed the IPDM with new updated one. I have Autoenginuity scanner with enhanced Nissan. It shows no codes, but when I try to reset ECU, it says "device is busy." It probably sat with dead battery for months. When I insert key, the red dash light with key pic blinks. I think this means security system is working properly. I have visually checked the harness for damage and found none.
I am wondering about possible fuel pump, ECU, BCM, ???

Hello my name is ***** ***** thank you for your question.

When you turn the key to the ON position, and all the dash warning lights come on, is the security light on solid?

Customer: replied 6 days ago.
No. It slowly blinks. Thank you. I need some walk through help on this one.

The security light blinks when the key is in the ON position?

Customer: replied 6 days ago.
When I turn key to on position, the light goes out.
Expert:  Jay replied 6 days ago.

That is good. Do you have a scanner to communicate with all control units?

Customer: replied 6 days ago.
Expert:  Jay replied 6 days ago.

What type of scanner do you have to do this? I am looking to do a CAN system call on all control units.

Let me know.

Expert:  Jay replied 6 days ago.

also to see if there are any codes stored..

I have Auto Enginuity with enhanced nissan (just updated).
Expert:  Jay replied 5 days ago.

Is that the bluetooth version? You use your phone with it?

Customer: replied 4 days ago.
No. It is on a PC laptop
Expert:  Jay replied 4 days ago.

Does it do CAN system checks?

Customer: replied 4 days ago.
This scanner should do everything Nissan. Except maybe key programming. I have done a full scan of all CAN systems and I get no codes, but when I try to reset ECU, it says "device is busy."

Well, that sounds like a Ecm issue. How often does it give you that warning?

Customer: replied 3 days ago.
Every time I scan. If I change the ECM, will I have to go to the dealer for key programming?
Expert:  Jay replied 3 days ago.

If you change the Ecm, yes. All keys would need to be reprogrammed. But a Mobile Locksmith can do that as well. So it doesn't have to go to the dealer. I would price it out and see which would be the most inexpensive alternative to have the keys programmed. It does sound like a Ecm issue.
