You can see on U Tube about how bad that is to do that. I sure hope they get it working at least for a year, because a lifetime warranty means nothing the second time your truck has to be towed. I sent it off to them this Monday and nothing from them so far. They wont return emails or phone messages ever.. I'm concerned this is going to be a problem..
5/29/19, After leaving them 4 emails and 3 voice messages with no return reply from anybody there, I called today and it seems all that's there are woman office staff that are there for no reason but to but you off once you have paid. Be aware that their lifetime warranty is only 2 replacements from the original purchase so I guess I'm at one now since the first one had no control to ignition coil and I had to be pushed off the road in 1000 feet. They said that they just received the PCM returned from me just yesterday. That's a week and a half from mailing it to them. Tiny print on there warranty explains, no labor is covered for warranty work even if it is their fault. Many reviews tell me their labor charges are almost the cost of the original purchase price, SO THERE IS NO WARRANTY, BE WARE! Also there return fee for cash back is half the original purchase price, after a 25% restocking fee plus me paying for all the shipping back and forth. I suspect they will send the same PCM back to me without any repair and I will be out 275.00. The 5.9 is a higher price PCM. I paid through Pay Pal and will contact them if needed, but CC EX can flat refuse to pay, which better business bureau say's is what always happens. I feel like I've been robbed !!

Has anyone fixed code p0627 if so how did you do it? thanks.
You have an aggravating situation, and I feel for you. That person should have checked to see if there was current to the fuel pump relay, and the ground control from the PCM as well as your wiring under the PDC where all your relays and some fuses are by the battery. He didn't check for current and ground at the pump and be God when he pulled the tank he left something off or overlooked the hoses because now you have a vacuum leak throwing that po449. You need to get it running first before you trust that code. If you wiggle the PCM plug closest to the fire wall or the ""right one"", "staring at the front of the plugs", with key on you will no doubt hear the relays click in the PDC . You and I both need a PCM my 99 Durango 5.9 is getting to me as well, and the first PMC from Car Computer Exchange would only power my ignition coil for one minute,, then strand me. It will take two or three weeks to get it back from them, back and fourth in the slow ass mail. I don't think any of those used made to work PCM stores are worth a dam. They simply don't have any way to test them..
Stay in touch..
