Impossoble to say with out knowing what the problem is.
Constant ground signal from the ECM, or injector could be faulty and stuck open.
The ECM is supposed to ground the injector to make it work. Either the ECM is bad or something that tells the ecm to fire the injector is bad. TAke it to a mechanic.
Blown fuse, bad connection, or ground.
loss of communications, many things could cause this from a bad ground, to cut wire, to a bad chip in the computer ecm
In a 2003 Buick LeSabre, the Engine Control Module (ECM) is typically grounded through a ground wire that connects to the vehicle's chassis. You can find the grounding point near the ECM, which is located under the dashboard, usually on the driver's side. It’s important to ensure that the ground connection is clean and secure to avoid electrical issues. If you're troubleshooting, you may also want to check other ground points in the engine compartment.
potatoes? carrots? the majority of veg?
scanners work for 96 vechicles or newer
Do you have spark at the coil? If not it could be the coil but I would put my money on a faulty ecm. Happened to mine and the repaired ecm fixed it.
ECM will not cause A/C to not work properly. some of the earlier mitsubishi's had a ground wire for the A/C going through the ECM. and i have ran into the circuit in the ECM that grounds it go out causing the A/C to not work on a few diffrent cars
AnswerFailsafe means that the ECM has snesed a problem and put the tranny into 2nd or 3rd gear to limp home. Could be wiring, solenoid failure, bad car battery (yes bad battery) or faulty alternator. This assumes that the ECM /PCM (ie: computer) is OK. Alslo could be a bad ground from tranny to chassis.
Sounds like the ECM is toasted.
Yes, The ecm sends a ground to the starter relay which in turns sends current (power) to the starter relay or moving pole shoe, however yours is equipped. The ecm receives a signal from the transmission position sensor so that the ecm knows whether the vehicle is in neutral or park. Thus only sending ground to relay when the proper shift position is attained.
