Fuel system woes - ZR-1 Net Registry Forums

Starman · 06-03-2022

Basically have driven the 91 twice this year to Costco. First time was for new Michelin PS2s and second time was to replace tire pressure sensor they broke. Car drove well both time and filled it up from about a quarter tank with fresh Shell premium and Vb Octanium octane boost. Both fuel pumps were replaced with Bosch maybe 10 years ago.

So after replacing the broken wheel stud from my friends at Costco, car will not start. Have a fast crank, good spark, no fuel pressure, no engine codes.

Did the wiring check at the tank, ohmed out fine. Did the pump test plug with both pumps hooked up and pulled 4.6A, but no pressure. Have not pulled fuses yet. FP1 fuse was OK. Car is in a lousy spot to get under dash.

Does anyone have the wiring diagram for the connector at the tank?

Open to ideas, I do have a FSM, but a bit cryptic at times.

Thanks
