IGNITION PROBLEM-'90 lumina APV 3.1L

I stoped the engine, OK. next day there is no gas throught injectors and the engine don't start.
The pomp starts and then stops like usualy on start, it is 12Vcc on hot wire of injectors, but i don't have any signal on the others.
I believe thats is a bad ground somewhere but i don't know where to look after. Please help me! Thanks

I am working on 90 LUMINA Euro 3.1 too. Do you have a spark? If you check for spark make sure you use a spark tester so you dont damage ignition control module. If icm is bad or if crank sensor is bad you wont get a signal that lets the injectors know when to fire. Did you check fuses under the hood at the front passenger side of car? I have heard that connections under that relay center get corroded sometimes too because of their location. SUPPORT OUR TROOPS. P.S. I HAVE A GM SERVICE MANUAL IF YOU NEED ANY MORE INFO.
