Reply to "Help... EFI Engine problems"

George PAdmin.

Toby,

I've never been involved with a Haltech system. But start with the basics, check your fuel pressure, is it dropping off, or too low to start with. 54 pound injectors are healthy injectors (possibly too big), but they need their rated pressure to provide their rated flow rate. Of course, check the pulse width (duty cycle) to the injectors to confirm they are within their electrical operating area too.
Check the condition of your spark plugs & finally scope the output of the coil. One of these checks should give you an idea where the problem lies.

Sorry I'm not more help.

Regarding the "EFI survey". One of these days I'll stick a system on my Pantera & show our community how it can be done, no headaches. Hint, think EEC IV.
