Hey all here.
Here's a conundrum that I'm struggling with.
This one has me stumped. The fuel per cycle reading is lower than another known good motor.
It is currently a non runner. UNLESS the starboard temp sensor is unplugged. It will then run but not very well.
Prior to finding out that it will run with the starboard temp sender unplugged the fuel pressure was checked. Vst thoroughly checked. Low pressure fuel pump checked. Temp senders resistance checked. Map sensor replaced. Fuel pressure regulator replaced. Injector leak down test done. Wiring from temp sensors resistance checked. Temp sensors swapped from port to starboard and the problem stays on the starboard side. Allegedly the ecu was swapped out with another motor to check. All that I haven't checked is the tps
Perhaps someone here has another idea that I haven't thought of.
