96 S-10 no start

I have 96 blazer that has a no start cond.I have fuel pressure & spark. I replaced the ignition ctrl. module & the ecm with a reman & had it flashed. Still won't start. It fires when gas poured in the tbi. any help would be app.

When you are cranking the engine are you getting fuel spraying from the injectors in the throttle body?

Are you sure you are getting constant strong spark? You have fuel pressure, but it looks like your injectors are not firing. Injectors are controlled by the ECM, which fires the injectors based on timing recieved from the ignition system, primarily the crankshaft sensor/ignition control module. You may have a bad injector connection, check all your connctions at your injector(s). Are you sure your ECM was flashed properly and is working?
