Obd1 port no power?

Hi,

Take note if the fuel pump primes when you first turn the key. If it doesn't, there is an inline fuse attached to the relay bracket at the right front of the engine compartment. I suspect either the fuse has failed or there is a wiring problem.

I attached two pics below showing the power supply. Letter M, which I didn't highlight, receives power from the same fuse.

Make sure the fuse is good. Also, if the fuse is good, confirm there is power on both ends of the inline fuse.

Let me know what you find or if you have other questions.

Take care,

Joe
