Angry A Little Help Please!!

Ok. .So i have a 30th Anniversary Z28 with about 64200 miles on it and it will not start. . just started doin this BS today. . before i bought it the dealer had new 02 sensors, plugs, wires, distributor, and a fuel pump put in the car. . i bought this car going on three weeks ago. . it was running fine yesterday. . i took it to a shop, where we had the fuel pressure tested and its hitting 41 psi. .the normal for these engines. . i dunno what it could be. . i have run out of options. .

Well its probably a spark issue if you're getting fuel pressure. Start by testing for spark at the plugs. Then test for spark at the coil. If your coil is sparking but your plugs aren't, you know its between there. If you coil isn't firing then try replacing that.

Yeah, be a little more specific. Does it at least crank, or is it completely dead when you turn the key?

Start by unplugging all the connectors at the underhood PCM and reseating them, making sure the clips lock. Might cure ya.
