Strange engine noise

That's one way. As long as the fuel rail is connected, I used to pull the injector fuses - both right there on the fuse panel. But, Pete put me on to flooring the accelerator - which puts the ECM in the "clearing flooded engine" mode (at under something like 400 rpm, i.e. starter only speed) which cuts off the injectors which = not having to pull any fuses. (When he told me about it, it was one of those "slap forehead with palm - DOH!! - kind of moments )

Just a thought...

I can understand about the injectors and keeping them from firing. What I'm concerned about right now is cranking the engine. The plenum is off and of course that means all of the ignition is disconnected. Is it okay to crank the engine in that state without risking damage to either the ECM or the CCM? I have enough problems right now without adding more.
I would like to get compression readings before removing the engine. Now is the time to find out if there is a problem in the right bank. The way my luck is going at this point I'm not banking on anything without confirming it.

Thanks for the answers and patience.

I cranked mine (compression test) without the plenum on. No problems.

NOTE: Jerry is right about pulling the fuses for the fuel pumps if the fuel rail is not connected - it will squirt a lot of fuel in a hurry, if you don't (ask me how I know that!)

Thank you Paul.

As for the fuel, I would imagine that would be quite a fountain coming out of there. Yikes! The car is in the garage. I can't open the right side door far enough to get to the fuse block. I may just reattach the fuel rail with the injectors sitting in place. It looks like #7's secondary injector may have been leaking so I would be able to confirm that.

I wonder, is there anyone that has the tools to time the cams who would be willing to loan/rent them to me? That's something I have wanted to buy but I had no idea I would be needing them now. Economics makes purchasing them now difficult.

Thank you,
