Car stalled on interstate with no warning, check engine light came on and we coasted to shoulder. We hauled it home and started checking it out. ( I'm a retired master tech, with no test equipment) Has stark and fuel, there is a relay module located abogve radiater that is buzzing. My looking at wiring schematics show 5 differant relays in it. My question is is it that relay module or possibly ecm?

The item you refer to is the CCRM. Constant Control Relay Module. It contains several relays invluding the fan relay, fuel pump relay, and power relay for the PCM. If it is buzzing, check the ground at the radiator support. Make sure that it is CLEAN and TIGHT! This is a very critical ground, and if the connection is lost, the car will not run.

Just got back from checking grounds and grinding to bare metal to insure positive ground connection, still no start and buzzing.

Did you check the ground wire at the radiator support with 3 black wires attached? If so, then check each of the wires for internal breaks. Also check that the radiator support is actually grounded.

The buzzing is usually caused by a weak ground or a resistance to ground. Since the relays inside carry a high current, grounding is important. Weak connections from the radiator support to the body can also be present.
