I'm Awesome
I updated the connect, well, my shop updated it. I was planning on adding a Racetronix hotwire kit but that keeps getting pushed on down the list.I don't think 12.5v is horrible. Maybe check some of your electrical connections..... voltage drop maybe?
I still have the OEM injectors, which are known for leaking. I'd still get a pressure gauge on the system, Though. My pump was likely a Delphi, as it was dealer purchased AC Delco.... not super impressed with it after the fact. I don't recall how long I had it before I had the starting issue. The other thing that I did when changing pumps was converting to the new pigtail/connector. Do you have the square 4 or flat four connector? GM redesigned the connector and the Denso pump I installed came with a new pigtail.
I pulled all my cables off and greased them, guess I'll keep an eye on them and take everything to be tested when I have the time. I'm sure it's something simple I'm glossing over.
