Default Why wont my 347 crank up

I have fuel, it is reading 38 psi, and I have spark. I can't figure it out to save my life. [:@] It just turns over without cranking. There is no loaping or anything. It just spins over freely like as if it has no spark. Somebody please help.

Is your firing order right? and is your dizzy right? and are you getting spark through the wire or just from the coil because i might be your rotor or your caps cracked? thats my guess o well good luck

My timing is set right and I checked my spark plugs by pulling them out with the wires still attached and I have fire shooting out the end of the plugs. I just don't get it. My ignition is all MSD and it's all brand spanking new stuff.

are your plugs wet with gas when you pull them out? If not your injectors are not working. spray starting fluid in the intake and see if it will try to start.

The plugs are not wet. I will try the spray idea tomarrow after work. I've had all I can take tonight. Plus my battery is dead. [:@]

I guess from the pictures this is a new build? Most likely it is the timing, check it again to make sure you have timed it to Number 1 on the combustion stroke not the exhaust stroke.

Try cranking the engine and turning the distributer while its cranking. Also double check to make sure fuel is getting through the injecters.
