454 crusader electronic fuel injection

[Mike Shirley]

"I have an after market fuel i

"I have an after market fuel injection system with a Holley intake on two 454 marine crusader engines and need some help finding out how to run a diagnostics test on the brain input. The serial # is (01227730)
on the brain but no name brand on it anywhere. Motors are running a little rich and loading up when at idle of 800rpm or better which makes no sense, spark plugs are changed every three months or so and gaps are set properly. Please Help!

Sincerely,
Jim Shirley

"Jim, If this was a Holley EF

"Jim, If this was a Holley EFI kit, you will need to check with Holley regarding diagnostics. Your S/N doesn't matter if the ECM was part of the Holley kit.

Sorry I can't be more help, but Holley is not included in any of the diagnostic software I have although they may well use MEFI, which is common. I just don't have enough knowledge of that system to be of much help."
