NO Start issue after Engine swap, HELP!

[xr_guys]

Hi 78F350,

Thanks for your reply, yes I saw the little pill inside the key, then I realized that was a transponder of sort.

The car ran before the swap, off course using the old engine. I was expecting when I returned the old ECU will resolve any security.

Thanks,

OK latest work and still no crank or start. Also OBD2 not communicating.

• New battery
• Check fuel pressure bypass relay, good pressure
• Check clutch switch
• Reconnect immobilizer module
• Disconnect radio fuse, maybe K & L lines interfering with after market radio

Currently the car top partially open or some people called service mode.

I’m starting to believed my key pill could be bad?

I still need to bypass the starter relay to temporarily crank the car to make sure that connection is good, what’s the best way?

Thanks,
XR
