John, earlier you said, “It is on warm
restart when ever thing changes and the injectors are getting the + from some
place other than the fuse.”
Power to the injectors doesn’t hurt anything. They
cant fire unless they are grounded with power on them.
Do you know if with the injectors disabled and the fuse
pulled so that no fuel can possibly get into the engine from the injectors, so
that the engine is running totally on the Webber, it starts and run fine when
cold and starts and runs fine when hot?
How about when the Webber is shut down and drained like Ed
and others have described and the engine is running totally on the injectors
and there is no possibility of fuel getting to the engine from the Webber, it
starts and runs fine when cold and starts and runs fine when hot?
The problem may turn out to be that you have incomplete
separation between the two systems, but you will not be able to determine that
unless you can operate the engine on each system independently with the other
system absolutely and totally disabled.
If it wont run on one of the systems independently at least
you will know where to start looking for the problem. If it turns out to
be the injectors it is probably that they are getting ground somewhere other
than the EC-2. They should have power (12V) to them all time but current
can not flow unless there is a ground. This is supposedly supplied by the
EC-2. if they are clicking during test, it is probably working like it
should and you are getting ground somewhere else.
Someone, Al?, suggested earlier that you power the injectors
and remove the connectors one at a time listening for a click to see if you
could find a ground on one or more of them. Did you do that?
Can you post a schematic of your wiring and plumbing systems?

Well I spent the afternoon testing the computer system and
after checking the grounds and the power to the injectors, I ran the engine up
to 180 degrees, stopped for a glass of tea and went back out to the shed and
started the engine, flooding, pulled the fuse quick so as to not flood the
engine. I have the upgrade's so I clipped the stethoscope to each
injector and ran the test mode for the injectors and each on was clicking, so I
tried a restart with the fuse pulled and the engine started. I unplugged
all the injectors and the engine started, so I guess the new set isn't working
any better than the rebuilds I bought from Bruce T. Is there a way to
test those injectors to tell which may be hanging open. I have two cycle
oil and MM oil in the fuel, so every thing should be well lubed, I did this
when I was having a condition with the rotor lube pump. I think I'll go
out this evening after it cools down and see if will still run with the
injectors unplugged. I'll have to wait till Tracy gets home to find out if it's Okay to
run with the Weber with the fuel side of the computer turned off.
JohnD....Thank you for your help!
