fuel issues
Hey guys. I have been having some issues and codes due to lpfp being too low 2a2d code. Pressure was all over the place. It would be ok on one day low another so I went ahead and replaced the lpfp with the walbro 455. Unfortunately, that didn't solve the problem. I figured it was just the lpf sensor because the car was running great and my hpfp wasn't dropping.... until yesterday. Went WOT and the car lost power and threw a buch of fuel related codes. 29f3 2aaf 2aae 2a2d 29dc (injector shutoff). With the 29f3 code I felt sure it was the sensor so I changed it today. Once again this did not fix the issue. Went wot and the same thing happened. Checked lpfp and it is in the 30s. So its not the pump...not the sensor... the only thing else that I feel it could be is the regulator. But I haven't heard of these really going bad. Does anybody have any experience with this or a regulator going bad? What do you guys think? Could the hpfp be going bad causing low pressure drops (i wouldnt think so)??? I am stumped other than the possibility of the regulator. Any ideas would be greatly appreciated. I am having a heck of a time with this issue.. btw. The fuel pump is installed correctly. Its working fine the problem was the same with the stock pump. Thanks for your time and tips.
