Could timing chain be broke.

Could timing chain be broke?
Update to this problem: I was told bt a FixYa expert to spray starting fluid into throttle body and see if it will start. I just tried to start with starting fluid, still no response. When I try to start it smells flooded, I smell gas.
Below is my original request:
I have a 1998 Isuzu Hombre 2.2L two wheel drive pickup (Made by GM is same as Chevy S10). Ok, here is my problem. It just suddenly stopped running with no warning. It will crank but shows no sign of trying to start. I checked the following items and all are good: ignition module, coils, has good spark, fuel pump is good and delivering strongly to fuel rail, fuel filter is new, battery is good. Now, I think the problem is the injectors. But before I remove the air intake manifold to possibley check the injectors is there anything else I can check before doing this? Is it possible that it could be the oil pressure sender that is bad or maybe the fuel pump relay? I know your probably saying that the fuel pump wouldn't run if relay was bad, but about 4 years ago my fuel pump stopped pumping so I replaced with new one and it still didn't pump so I wired it directly to a wire that was hot only when ignition key switch is on. That solved my fuel pump problem. So, what I'm thinking is: since I bypassed the fuel pump circuit 4 years ago could it now be this circuit that is shutting down power to injectors even though fuel pump is still running due to bypassing the circuit. I'm a member of FixYa and I provide my expertise in solving washer and dryer problems. I'm a mechanically inclined person but auto mechanics are not my specialty, I'm hoping that it's yours if your looking at this. Please help.
