can you get an injector noid light? They are available at most parts stores and inexpensive. It should flash when cranking. You unplug an injector and place on connector

does the security light stay on with the key on?

Customer: replied 11 months ago.
no
Expert:  Tim's Auto Repair replied 11 months ago.

ok,,will it start with a prime?starting fluid or a little fuel into the throttle body?

how much fuel pressure does it have?

Customer: replied 11 months ago.
No psi 55
Expert:  Tim's Auto Repair replied 11 months ago.

ok,,

so it wont start even with a prime?

if not,test for a spark again,,it should fire with a prime if it has a sprk regardless.,,if it doesnt,im going to think it has jumped time[not likely with this engine]

again,confirm a spark on the plug wires
