I have a 95 3000gt SL, I just did a valve job and some other upgrades and now it won't fire.
Double check your timing marks. If they are found to be off do compression check to test for bent valves. Also check cam and crank position sensors. Make sure they are fully plugged in. Also did you keep your cams in correct order when you did the valves? If not sure that they went right back the same way the came out better remove valve covers and check them. Each one will only work in its original spot.
are you sure that you got the cams in the correct spots ?
