Swapped computer to an A9L. No luck. Fuel pump appears to be working, hear the priming noise and I smell fuel, but the mechanical indicator on the schrader valve indicates NO pressure at all.
I installed a new FPR and still NO fuel pressure, but I smell gas.
I installed two new relays from Ford at the ECM and Fuel pump relay.
Question: I have a FMS mass air conversion, originally had a A3M computer. Is there a chance the A9L is not compatible?
I actually got it to fire with the original speed density computer earlier, but it obviously ran like crap.
But it won't even manage that with the A9L.
I'm beat after working on it all day.
Thanks. Time for beer.
