good morning my name is ***** ***** I will assist
I have seen this several times and has been a failed injector pump. I have attached a code chart for you to review.
hard to say without removing and dis assembling. it does happen. my first one drove me crazy as I never suspected a new part causing the failure. you always assume new parts never fail. at least the part will be free for you just have to do the labor of replacing.
please dont forget to rate me as it is the only way I get paid for my service
