After almost a week of driving my truck around town, the injection pump from "Hector with Injectors" of AZ and on ebay, failed. And the best part about it they never answer the phone and charged me twice... So, anyone out there looking for a rebuilt injection pump, be cautious and do your homework, best advice would be look for a local shop that can rebuilt... I am still dealing with the credit card co. to get my second charge refunded... And now I am in the same situation as before, but with two failed injection pumps...
