My 89 Formula 5.7 TPI won't start without a blast of starting fluid. I've tried all suggestions on this forum so...I'm replacing the fuel pump and injectors. It is basically stock but does have a AFPR.

Stock is 22lb right?

I don't want to change the prom etc. so do I have to use 22lb or can I use the more readily available 24 lb from LT1's without changing the prom?

No Accell after what I've read but which Ford is the right one?

Gracias!

 

24s should be fine especially if you have an AFPR to help dial it in (yes, 22 is stock).
