1994 FORD ASPIRE WILL NOT START

Hello: I have a 1994 Ford Aspire auto trans 1.3 ltr. It just quit while driving, and will not start. Fuel pressure test good, spark tests good, compression on the low side, but still ok. Scope on fuel injector shows a sawtooth wave at approx dist reluctor speed. Need pinout of ECM and where trigger for fuel inj comes from. Chilton manuals only tell how to change a flat, are worthless for this kind of problem. Need detailed electronic schematic of dist outputs and ECM inputs
thank you
Darryl..
