Replaced Head Now no SPARK
Ok... here I go. I replaced a head with a rebuilt from Odessa Cylinder Heads AKA: Clearwater. I went step by step using correct torque on every bold, nut, and screw. I have all my vacuum lines hooked up and as far as I can see all my electrical is good and in place where it should be.
The first time I go to crank the motor after completing the job I notice I didn't have any fuel going to the fuel rail. After some looking around I noticed I pinched the plastic flex line right at the firewall. Fixed that I got fuel.
The next time. I noticed I'm not getting spark. I have a spark tester with a good ground and not getting any spark at any plug... I check the coil and no spark there.
I'm lost and don't have a clue what went wrong. I cranks good got fuel but no spark.

Its brand new. I was chasing a misfire.
Also the dis cap, rotor, plugs, wires, temp sensor, thermostat, fuel filter, air filter all have less that 1k on them.

That was it... Thanks. I found that I had loosen a nut on a ground stud at the dip stick that I didn't need too. It has the ground wire for the ignition coil on that stud.
Runs like a champ!
