Great title i’m sure.

Motor won’t turn over. Spark plugs get spark, fuel filter has pressure. Fuel regulator has pressure too.

but the fuel return line has no pressure. What could it be?

Local mechanic says the “injectors aren’t getting signal”

What could cause that?

Swapped ECU, checked relays, fuses.

Recently replaced the MFR due to the S3 blinking light.

TIA
