2005 m7

[cat10]

Hey everyone. I need some help. I recently acquired an m7. Was told it needed an oil injection pump. Got it cheap so if it’s junk I’m not out much. It has a can on it. It will start right up but that’s all. When I throttle it it dies. 120 lbs compression on both cylinders, pumping fuel to the rail for injectors, has good spark. Any ideas? I don’t understand how the oil injection pump can cause this? It does seem to be pumping a lot of oil through the engine. I’ve heard when the pump goes bad it sticks wide open. Any help would be appreciated

Check the throttle position sensors and then see what plugs look like - maybe someone thought the oil injection pump was bad and added oil to the gas tank and it’s running super rich. You should find position sensor bypass plugs in the tool kit.

The sled doesn’t have anything with it other than second motor and another seat. It’s straight gas in the tank right now. I’ve been told to pinch oil line and put mixed in it. I’m just not convinced that is the problem. Looking for good tips on what to check for. I will research how to check tps. Thanks for your help

Unplug the throttle safety switch to isolate that (different from the throttle position switch that's on the throttle body). Broken primary spring can kill a sled when you try to take off too.
