What spark-blue or yellow/Fuel is it the correct pressure?
To get this baby to fire up all we need now is the correct valve and ignition timing. If its not there it will never start.
Valves opening and closing on the wrong time/ignition is also firing on the wrong time.
BTW you sure its not being cause by a massive vacuum leak?
Recommend you perform a compression check and report back ASAP.

Good compression, seems that the plugs were fouled with fuel again, evidently the fuel pressure relief valve is leaking, this is the third one, i think i just have rotten luck with mechanics. Anyone out there live in the san bernardino area need a job that can make this run???

Have the fuel pressure check
Could be your pressure regulator or obstructed fuel return line causing the problem.

yes, we did notice fuel leaking on plenum, but unsure if fuel pressure regulator or two of the injectors that were replaced. am talking to a guy now who might take the job on---it is so hard to find a decent mechanic nowadays. i appreciate all your feedback that you have given me! many thanks, colleen

Suggested Repair
Check fuel pressure and inspect the fuel pressure regulator and fuel return line, since fuel was leaking on the plenum and the plugs were fuel-fouled. Also verify valve and ignition timing and rule out a large vacuum leak if pressure is normal.
Conversation Summary
A 1989 Chevrolet Camaro V6 would not start despite having spark and fuel. The expert advised checking spark quality, fuel pressure, valve and ignition timing, vacuum leaks, and compression. Compression was good, but the plugs were fuel-fouled and fuel was leaking on the plenum. The expert then recommended checking fuel pressure and inspecting the pressure regulator or an obstructed fuel return line.
