your computer has a constant current going to it through terminal BATT and it keeps a small memory. use the link i posted above to connect T and E1 on the ECU to start diagnostic mode. check for codes and report back.

make sure you are getting spark and fuel. remove a plug and ground it on the head and have some one turn it over.
ensure your getting fuel.
test your cold start injector:

also test your injectors:

if further inspecti0on is required listn for fuel entering the tank. your pressure regulator may not be working properly. check for vacuum leaks to the FPR and possibly check the pressure on the rail:

it sounds spark related to me because if you sprayed fuel in the intake it should have sparked up assuming your timing is close enough.
maby check to see your ign coil and igniter are within manual specs still. check your fuses.
