Need some help please. Here's the details on my son's sled. He bought this on a salvage auction last spring. Its an 06 motor but was sold as an 05 so not sure if that was a mistake or what. Tunnel has been replaced and there is no OE VIN. Seems to start and run fine until you get to about 3/4 throttle. It cuts out and loses power. It does not fall flat on its face, but is definitely not running full power after 3/4 throttle. It has been flashing codes 3, sometimes 7, and 10. But it only flashes the code once and moves on to the next. When it runs one cycle of the codes, it stops flashing any codes.
We've replaced plugs, TPS pigtail, and TPS. TPS set correctly.
Here's what I've checked:
Fuel pressure is good both when using a power supply and when running. I tested continuity on the stator and it is also good. Should I check voltage output from the stator, and if so, how is this done?
I suspect it may be a fuel issue and subsequently an injector. How do the 2 injectors per cylinder work? In parallel or sequential? Can you test the injectors without pulling the engine?
Another thought - there was enough 05 parts on this sled when we bought it (fuel pump, for example) that we are questioning whether or not it has an 05 ECU. Not sure if they were the same between 05/06 and if they would even work together, but just trying to rule that out also.
Thanks - Matt
