RF Interference with EFI System

[speedster]

Thanks for the info Sparky.
Sounds like one central ground point would be better than an isolated circuit for the water pump. I have always run a ground wire from the trunk mount battery to the front of the car instead of just relying on frame only ground. I will definately shield the crank trigger pick up.
The water pump is a Meziere 55 gpm 300 series.
The crank trigger is Electromotive Direct Ignition.
I guess I will bring a spectrum analyzer home from the office and check for interference once everything is set up.
My biggest fear on any of this is to have a signal that would cause a dangerous lean out or plug misfire under full power/full boost. Then I would have a very pretty, "blown" engine.

Thanks again.
