    Control pump circuit low code, few ?s

    Guest-only advertisement. Register or Log In now!
    So I just got done replacing my timing chain, oil filter housing, fuel filter and a few other maintenance items. The car started right up ran great. I drove the car about 10 miles and it desided to stumble almost like it hit fuel cut. So I drove home, as I pulled into the driveway the car died and would not restart. The car did not have this problem before I changed the timing chain could it possibly be off a tooth. The only code I get from the solus is fuel pump module circuit low. Am I correct to believe that if the timing was off I should have a cam sensor code correct?. Thanks for any help you can provide

    Make sure there is no air in the fuel filter lines.

    I don't think it's a air issue as I was able to drive the car 10 miles. The car also will not restart or even attempt too. How would you bleed air out if it was in the system. I pulled the fuel pump fuse and allowed the car to run out of fuel before changing the fuel filter, could that have caused a issue.

    Ok definitely not a air issue, I removed the fuel line coming from the tank and I am getting no fuel from the tank to the high pressure pump. So I'm thinking either the pump in the tank is junk or I read there is a control module for that pump that could be bad. I checked all the fuses and their good
