Troubleshooting: car wont start after upgrading fuel pump w/ higher inj cycle.
i have a b series turbo ek hatch. i got tuned on a walbro 255lph. my injector duty cycle was high so i upgraded it to a walbro 525 with a relay . now my car doesnt start. it just cranks ..my fuel pressure is set to 60psi . could it be that my car is so rich now that it wont start. ?

What was your fuel pressure prior to installing the pump? |
Re: Troubleshooting: car wont start after upgrading fuel pump w/ higher inj cycle.
are you sure your relay is wired correctly? There is some misinformation about how to wire up a relay, when upgrading to a larger fuel pump (as well as larger power and ground wires). I followed a wiring diagram online and it drained the hell out of my battery. Had to swap the two wires....+12VDC battery power wire and fuel pump feed power around and all was good.
The diagram below I made below is the correct way to wire up a larger fuel pump. https://cimg8.ibsrv.net/gimg/honda-t...4e6d1e567e.png |
