Am I the only one who can't find this thing?  I'm trying to do a compression test (through VFAQ) and I can't find the stupid coil connector.  Am I a moron?  If anyone could give me a detailed explanation (or a simple one, whatever works?) of where this freaking thing is so I can unplug it, that'd be great! :)

The coil connector is right below the fuel pressure regulator (well, just underneath the spark plug wires below the FPR).

just pull all your plug leads its easier than reaching way down there. Just don't mix them up  :wink:

When I do the compression test, I just pull the MPI fuse.

I'm with Chris on that one, it's way easier to grab.

On a 1990 the cam angle sensor can be easily unplugged.  Follow the wires off the bottom of the sensor to the firwall.

Lowell - So I can pull off the cam angle sensor instead of the coil connector?  

And Chris - I would definatly only go with the MPI fuse, but its that line in the vfaq that has me a little concerned

"3. Unplug the coil connector, it’s on the right side, at the back of the block. You could get a nasty shock if you don’t."  In addition to that, I was reading a post @ dsmtalk.com where someone was saying if you don't disconnect the coil connector you run risk of burning a coil.

I'm thinking if there is a current running that shouldn't be, it might damage my car in some way.  But again, I'm not too experienced with this, so if you and Ryan both think so, and have done so without hurting your cars, I'll go for it :)  Thanks again you guys.

You won't burn a coil.   :roll:   Coils only heat up if a current is flowing through them.  To burn a coil you need either a high continuous current or a much higher than normal voltage (like using a race-only ignition with non-race coils).   If you disconnect the spark plugs, then a current can't flow.

As for the nasty shock, the actual metal contact is deep inside the spark plug wire boot.  Just be carefull where you put the boots.  I kinda bunch them together, and secure them well away from where I am working.

If you unplug the cam angle sensor, the injectors and coils will not fire because the ECU doesn't think the motor is turning.  If you only unplug the coil pack the injectors will still put fuel into the motor.
