Hello y'all!
I have the Pro Flo 4 kit for my 302 (#35940) as well as the fuel pump kit #3604, and it seems that when I'm cranking so start the engine, my fuel pump is not working. It is pumping fine right before and after. I can monitor data when trying to start, and I see the fuel pressure dropping to 0PSI as soon as I try to start the engine, from around 50PSI just before that. While troubleshooting, I found out that two wires of the main relay were somehow badly wired - contacts 30 and 87 were swapped. I'm gonna replace the relay tonight, but from my understanding, it wouldn't make that big of a difference since that only meant that 12V were always at the exit contact. So if it is not the relay, what could cause the fuel pump to stop when cranking? My only two guesses are low voltage, but that would disconnect my ECU from the bluetooth tablet when cranking as well, which is not, or a bad ECU... Could it be so? Any ideas would be appreciated.
Thanks guys!
