94 Camaro 3.4L starting problem

I am working on a 94 Camaro 3.4L i replaced the head gaskets on this car about 3 months ago or so. Well he took a trip about 2 weeks ago and we got hit with alot of snow and got stuck a couple times (no big deal) so he parked the car for a couple days and drove his other vehicle. Well it sat for 2 days and he went to use it but it woudln't start so I went over and looked at it and I could not get it to start, I checked, fule pressure - 46 psi (not sure what is suppose to be but this should be sufficient enough to start), checked spark - good, checked compression on 5 cylinders - good. I have no idea what it could be any help would be greatly appreciated.

Thanks
Joe

sorry it is actually a 1995 Chevy Camaro 3.4L. Any Ideas????

Since you're getting fuel readings and confirm spark, I assume it turns over, just won't catch?

Yes, it turns over just won't start - I am at a loss.

Is the security light flashing?

I didn't notice but I asked him and he said NO The SECURITY LIGHT does not flash just comes on then goes off

Have you checked to see if there is voltage at the injector connectors using a noid light or I think a "194" or "197" bulb by straightening out the fillament wires ?

Have you tried spraying starting fluid in the throttle ?

Is it an orange, weak, or blue/white, strong, spark ?

Just a few thoughts
