Sounds like you have an injector problem. Check for 12V on each injector gray wire. It comes from the oil pressure sw with key on and oil pressure above 7 lbs.
If you have voltage you will need a noid light to check for a ground pulse from the computer. The computer has two outputs that pulse the injectors. 1-3 and 2-4. You can't check the ground pulse with out a noid light because it will load the computer circuit.
The outputs are on C-10 and C-12 of the computer. I strongly suspect one of the two problems.
Broken 12V connection to 1-3
Bad computer output for 1-3 pulse
It can't be the module because it provides reference to all 4 injectors to the computer (2 wires lo and hi on pins D-8 and D-9)
Let me know
