My van doesn't start. Was idling high for a few

My van doesn't start. Was idling high for a few months, finally something went out, it was extremely hard to start and stay started. It acted like it wanted to start, and I could almost hear it start for a second but then nothing. The codes are gone due to battery dieing. I've changed TPS, now doesn't even act like it wants to start. Changed fuel pressure regulator, no dice. I'm getting lots of fuel spraying out of the throttle body, but no start. When I try to get codes, I hear a click from the egr vacuum switch, and a gurgling sound coming from under the EFI. Egr diaphram seems to move freely. Any idea what my next step should be?

Optional Information:
1991 Chevrolet G20 sportvan 5.7ltr 350

Already Tried:
Changed TPS, Fuel pressure Reg. Checked for codes, hear a clicking from egr vacuum switch, and gurgling from under EFI.

I'll check the spark. Would the injectors still spray without sufficient fuel pressure? Seems like they are spraying alot of fuel. I would almost get a start before I changed TPS. Seemed easy, could I have installed that incorrectly and now have 2 problems? Just want to make sure I didn't screw thing up further. Would fouled plugs or not enough spark cause a trouble code?

Both can cause troble codes indirectly they could not be firing propperly and cause the O2 sensor to read rich exhaust and set the lighton.

Could also be the cause of your no start.
