Hey guys I have a Hyundai 30L-7M with a no start condition. It will fire on brake clean. I replaced the regulator due to a ton of fuel pressure coming from the regulator to the epr. Still will not start. The diaphragm in the mixer is in good shape with no tears or no Gunk.
I jumped pins one and four in the diagnostic port to get flash codes. It has a bunch of codes. They are 6420, 1173, 1644, 2123, 1626, 6530, 1611.
Any help would be much appreciated as I cannot find the description of these fault codes anywhere. Thanks!
