power steering flush
On other vehicles, when flushing all the power steering fluid, I would
disconnect the cam position sensor and route the return line into a waste
container and crank the engine for about ten seconds to drain the system
while adding new fluid until it runs cherry red again. On the 2010 F 150 4.6
3V engine you cannot get to the connector without unbolting the AC
compressor and moving it out of the way. I was thinking about simply
removing the fuel pump fuse/relay so the engine will not start. Is there an
easier method or preferred way to crank these engines without starting?
Pushing the gas peddle to the floor while cranking. Should put it in cranking mode. No need to disconnect anything
Removing the fuel pump relay would do it.
Bob: Just thought of something. If I used a 12V push button start button hooked up between the battery and the S terminal on the solenoid, would that spin the engine. Since the key would be in the off position, there should be no power going to things like injectors, plugs, or fuel pump?
OJ, I think that would work, but not sure if it would cause electrical issue elsewhere. I sure wouldn't think it would cause an issue. The pushing the accelerator to the floor method using a helper, in my opinion would not be safe.
