I have a 2011 Dodge Durango and in Sept of 2015 the dealer installed a fuel pump bypass on the TIPM. This year sometimes when the car won't start. On hot days I needed to wait hours to cool down before it would start. Recently it occurred on a cold morning start. The issue is if I use the push button starter the starter turns and engine never starts. I slip it into reverse to stop the starter. If I use the key, I can turn it to run, then start and the car starts right up. Sometimes I need to cycle the key several times before the fuel pump starts. I have checked the dealer bypass wire and it appears they did a first class job with terminal connector and shrink tubing. However as soon as I touch the bypass wire I never have starting issues for a while. Can a fuel pump run intermittent or is it more likely the TIPM module? This car acts like its in the 1980s with the old control modules.
