Seems like there was a problem with my previous post. I have 2x of the above. Both motors were partially submerged. I replaced the powerhead on one and buttoned it up. Now, when I start it, it runs wide open for about 20 seconds, at which point I get a steady beep and RPMs are limited to idle. Throttle is closed when this happens. 3x different TPS and 2x different ECU and same results. I have 5v on one pin, 4.5v on the middle pin, and ground on the 3rd pin on the TPS connector that goes into the harness. Seems as though all three fuel pumps and air compressor are working. Should I try swapping wiring harnesses or fuel rails? Any other thoughts?
