I'm trying to track down a mysterious issue of the CRD dying after running for a few minutes, then not restarting. I was testing the injectors and unplugged the cam sensor so it wouldn't start, but it ended up starting. Tried it a couple more times and it kept starting. What would be the cause of this? Thanks.

Mine will do the same, but only for a few seconds. It startled me the first time.

What is this, a CRD virus? Seems like a lot of you guys are having this no-start-when-hot problem.

It seems like it will only run with the sensor unplugged if the engine is warmed up. I left it unplugged overnight and tried to start it. It tried to start, but didn't completely fire. I then plugged it back in and it fired right up.
