Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

that 1282 is a fuel pump relay circuit problem, we need to troubleshoot that first,

I've replaced the fuel pump, asd, and fuel pump relay. Couldn't find anything else to check in relation to that circuit. Suggestions?

oh yeah I got a ton first of we need to verify voltage from the pcm that tells the relay to turn on, with key on and try in start position as well check c18 for power and c20 for ground , there should be small numbers indicating pin position
