ECM DEAD??
|
|
|
I JUST REPLACED THE CAP & ROTOR ON A '92 DAKOTA 3.9 V-6. WHEN I WENT TO START IT...ALL I WAS HEARING WAS "CLICKING". I PULLED THE NEG. POST TO CLEAN POST-CLEANED POST. AS I WAS PUTTING THE CONNECTOR BACK ON I HEARD MORE CLICKING. I DID IT SEVERAL TIMES-ALWAYS A CLICKING. IT SEEMED TO BE COMING FROM THE RELAY BOX ON THE FENDERWELL. I CLEANED THE POSITIVE POST.
I TRIED RESTARTING. MORE LESS-NOTICEABLE CLICKING. I CHECKED THE BATT V'GE. WAS 11.5V.
I PUT THE BATT CHARGER ON IT @ 1O.OV SETTING. I LEFT IT THERE FOR ABOUT 15 MINS. I TRIED RESTARTING-NO CLICKING.
I CHECKED THE BATT V'GE=12.3. I TRIED STARTING AGAIN WITH NO CLICKING. I DID NOT EVEN HAVE ANY DASH LIGHTS THAT NORMALLY COME ON WHEN I TURN THE KEY ON.
I REMOVED THE NEG TERMINAL AGAIN TO RESET THE ECM. I DID NOT HEAR ANY CLICKING FROM THE RELAYS WHEN I RECONNECTED.
I AM GETTING A 4.83V/4.92V/5.0V SIGNAL FROM 3 SENSORS. I AM ASSUMING THE ECM IS OK & WORKING.
THE "KEY ON"/START SYSTEM SEEMS TO BE DEAD. WHAT SHOULD I LOOK FOR TO 1) GET A SIGNAL TO RELAYS; 2) GET POWER TO THE DASH LIGHTS AT "KEY ON"; 3) GET THE STARTER TO CRANK.
THE V'GE ON BATT NOW IS 12.8V.
THANX.
