Crankshaft Position Sensor

[JoshErnst1074]

By little grey box do you mean the icm? And I've tried resetting the battery, and this engine doesn't have a cam position sensor. One thing I forgot to mention, the ignition switch in this truck is all messed up. It starts without a key and sometimes the starter never disengages. It gets stuck until I yank the battery.

Yes,the ICM,Take time to switch out the key switch,may be the problem but make sure you have a good ground on the ICM,upper left corner screw hole,clean the brass tab and clean the screw hole in the intake.If you have any concern its not grounded enough,run a wire from THAT screw and get a ground on the engine.

I checked the icm to see if it was getting power. 12V. Also checked the ground of the CPS and it's also good. I also posted another thread with some cel stuff.

Well here's something interesting. There is no screw in the upper left corner of the icm and no brass tab.
