94 lt1 no start Looking for some help. This thing cranks over and has fuel. I hooked a scaner to it and there were no codes. I could see the rpms going up when i was cranking it with the scaner hooked up. it maybe sounds like its may be out of time. Any ideals what to check or replace? Thanks for your help.....

Did you just do some mods? Cam swap?
Did it happen all of a sudden?
Has the car been sitting for a year?
Hook up a fuel pressure gauge and verify the actual fuel pressure.
Disconnect the coil wire and test for spark at the coil.
Check all of your fuses under the hood and in te car.

Test for spark at the coil by removing the plug wire that goes to your coil seen in the picture below (red box, yours should be black though). See if it arcs to metal when you try and turn the car over.

Diconnect the wire coming from the coil and going to the distributor. Hold the distributor side close to some metal point on the block. You should see it arc to that spot. If it doesn't, that could indicate a bad coil or optispark.
