i bought this truck at a great price. when i bought it someone could be in the truck cranking it while another person was wiggling wires around on plug for ecm closest to front end of truck and it would start and run. it got to the point where that wouldn't work anymore to start it. so a local mechanic shop diagnosed it to have a bad ecm. i know a bad ecm would stop a vehicle from starting, but moving wires by the ecm then the engine starting makes no sense. would a faulty ecm do this? if i do change the ecm would the new one need to be programmed to this vin number or is it just a plug and play?
