Ed:

The injectors are new but not from  Mazda.
I pulse tested them by hooking them up to an air compressor set at 45 psi.
no test of duration but you can feel air pulses when you spin the engine.

The coils are new 98 Chevy coils.  This happened when I found out that Mazda
wants $1,200.00 for their coil set and Tracy says they should be modified for
aircraft use.
One coil per plug and Tracy modified his EFI to handle them.

The only other item that may be a problem is I am only showing about 25 psi
fuel pressure.  This has to be the pressure regulators on the fuel rails
since the pumps are the ones supplied by Tracy and rated at 90 psi.

Still Trying.

Hank

That will do it. The amount of fuel injected is directly
related to the fuel system pressure.
