Question about 1997 Chevrolet Tahoe

1 Answer

I HAVE A 1997 GMC YUKON, 5.7 ENGINE. RECENTLY WHILE DRIVEN THE ENGINE JUST SHUT DOWN. THE ECM-1 FUSE WAS BLOWN. AFTER REPLACING THE VEHICLE STARTED BACK UP, WENT MAYBE A 100 YARDS AND IT BLEW AGAIN. I PUT A 30 AMP FUSE IN THE 20AMP FUSE AND WAS ABLE TO GET BACK HOME, ABOUT A MILE. THIS PAST WEEKEND IT WAS PRETTY WARM SO I DECIDED TO TRY IT AGAIN AND LEFT THE 30AMP FUSE IN. DROVE APPROX. 3 MILES AND IT BLEW AGAIN, SO I PUT IN ANOTHER 30 AMP FUSE. DID THIS 3-TIMES BEFORE I FINALLY GAVE UP AND CALLED A WRECKER. I COULDN'T GET IT TO START BACK AT ALL. WAITED FOR THE WRECKER ABOUT 30-40 MINUTES AND DECIDED TO TRY TO START IT BACK AND IT STARTED, DID NOT BLOW THE FUSE THAT TIME.

Sounds like the computer has short in it. You can get a computer at Oreillys auto parts for around $140.00. You will need to call the part store and order the ecm and give them some info on your engine, so the replacement ecm can be programmed for your vehicle.

here is a little help. if you need more I am on facebook. There are 2 ignition 1 voltage circuits supplied to the Engine Control Module (ECM). The first ignition circuit is provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition 1 voltage circuit is supplied by the run/crank relay through a fuse, and is used to power the remaining internal ECM circuits. If the ECM detects a voltage difference between the 2 ignition 1 voltage circuits, DTC

I replaced the fuel pump relay, noticed that i had a blown fuse marked ecm. repaced that.ran truck for around 20 min.turned off. when i went to start again it wouldnt. looked at that same 20 amp fuse


There are two ECM fuses - marked ecm 1 and ecm B.
ECM B powers the fuel pump and the Veh control module which handles most of the sensors.
ECM 1 powers the ignition module, coil, injectors and the rest of the engine sensors.
You may need a repair book with diagrams to check all of the circuits for shorts.

1997 yukon keeps blowing ECM-1 fuse, 20 amp. Ran for awhile after replacing, then blew fuse again, and again?


Hi, here is what runs on the fuse: ECM, injectors, coil, MAP sensor, crank sensor, IAT sensor, EGR solenoid. Of these, only the EGR solenoid has a delayed operation. Recommend you disconnect the EGR solenoid to see if the fuse will hold up. The solenoid is next to the thermostat housing as shown below. If the fuse doesn't blow with the solenoid disconnected, replace the EGR solenoid. Please let me know if you have questions and thanks for using FixYa.

1997 yukon, keep blowing ECM - 1, 20 amp fuse under hood . I had replace fuel pump a few months back, could it be a bad connection on the fuel pump?


i would check wire harness for bare wire but first i would look under that massive fuse box under hood, i kept blowing air cond relay and i traced it back to corroded connection on that fuse. not saying this is it and i hope it is that simple for you. other than that research exactly what the ecm-1 CONTROLS and search,test,grounds those systems. If i can come across any other symptoms i will forward them to you.

I have a gmc safari van that has the key stuck in the ignition it is running and will not turn offf. How do we stop the vehicle from running?


Probably the easiest and safest way is to go to the fuse box and pull the "ECM" fuse. If the fuse box does not have labels for which fuse is which, just start pulling and replacing fuses until the engine quits.

Vehicle chokes, sputters, and then shuts off


Start with the simple and replace the fuel filter. The fuel filter may have reached the end of it's life time and is dirty causing the issues you have. The worst is the fuel pump it self has gone bad and needs to be replaced, the fuel pump should be producing 62 to 65 PSI when the engine is started and should drop no more then 5 PSI when the engine is running. You can check the fuel pressure at the shredder valve with a fuel pressure gauge. Good luck and keep me posted, be glad to help get your Yukon running 100% again.

1997 gmc sierra shuts off while driving


Had same problem with a Yukon. Turned out to be a bad fuel pump (Won't show codes.) When cold ran fine, heated up, no pressure. Would start after sitting for about 1/2 hour. When engine dies on you check for fuel pressure under the hood.
