I'll link a couple videos I used but couldn't find anything worth my time on the forum. Plus I'll link the codes I got to start this. Basically HPFP, MAF #2, and cylinder 5 misfire. Didn't want to deal with injectors and I know there is a 10/120 extended warranty on them anyway so figured I'd start with the pumps. Then if needed the MAF and if still an issue let dealer tackle the injector.
There will also be some differences depending on what year you have. I am 2014 March build. So the HPFP had a new magneto and plug type which required splicing the wiring.
Ordered all from FCP Euro and thanks to them for all the parts I needed based on their system recommendations
