1992 Pontiac Sunbird, 3.1 litre, 140k miles.
Was running fine one day next day I come out and it wont start. Check everything til' i found there was no fire to the plugs.
I checked all fuses on fuse panel all appear to be good. Then I replaced the coil pack, still no fire. Then replaced ECM, still no fire.
So thats where im at. What should I check, for it not firing?
I was wondering about an anti-theft system being set off or somthing, is there a anti-theft system on this car? Those usually disable the fuel pump pretty sure. But i have fuel pressure.
Thanks for your time

Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
