Ok this is the scenario, I have installed valve covers and new gaskets, intake manifold, welded all A.I.R ports closed. I also installed a 1" aluminum carb spacer waiting on the oil change due to the fact I must remove the oil filter to install the headers. I check the oil twice it is super dirty but its in there. Also after all these part were installed the car ran out of gas, and the PCM wiring harness was removed except for the TCC wiring. What could be the problem?
