I’ve been reading forums about the issues people go through with their trucks and it’s different from my problems. I replaced the battery /alternator and my vehicle won’t crank over. The weird thing is before I even put the key in the ignition or open the door , my warning chimes goes off from the inside. I check the fuses and I think they may be ok. I think it may be the ecm because on the display it says service everything (4 wheel drive/air bag/stabilitrak
