2002 2.2 ecotec no start

[forkliftfixer]

driving down the road then the car stalled .tryed new coil pack no start.once in a while it will pop when i try to start.i used a spark tester on a couple plugs an i have spark.it could be a little stronger but i have spark.i used a gas compatable hot start .no start.if i let the car sit overnight and try to start it it will backfire or pop once than nothing.i even pulled the air box poured fuel into throttle body no luck. i took psi on fuel rail an its at 50+psi.i took a test lead ran it to engine to neg at battery no luck.the main plug that is under air box had been probe and corroded and previous mechanic repaired wire.it was power to dash.this car ran so smooth and strong .

Use a noid light and check for pulse at the injector.

Check for a plugged air filter. Look at timing belt you maybe slightly out of time.
I would check for spark at all cylinders.
