Bad oxygen sensors?

Fuel pressure has been verified, except for with the engine running because the engine won't start. I'm trying to find out what else could possibly make the engine not run. It seems as though the injectors aren't getting a pulse signal, and I need to know what to check for that.

I'll try it, and let you know. Thanks

I put a noid light on the injector plug in, and both sides of the plug make the light come on but not flash, this was done with the engine being cranked, but not running.(Since it won't start).

So does that mean I need a new computer, or could it be a short somewhere in the wiring?

Okay, I'll try that. Thank you.

Okay, I got the other problem fixed. Finally!

I got a new problem though, there is a really foul smell in my vent system, and around the truck, kinda smells like dead rat, it's really bad when I turn the dash blower on. No vibration in the fan, just a foul smell !
I would like to know what I need to do to get the culprit out before it gets really nasty. This smell is really bad. Please, help.

Was told it might be oxygen sensor.
I have replaced everything else it could be.
So didn't know if it was a O2 sensor or oxygen sensor.
If it is by the first converter or what.
It has a new fuel pump and filer.
