I am so fking fustrated with my car its pissing me off to the point where i wish i never done anything to it. First no power after a brand new motor was droped in. Now my computer is throwing the 4 code which states my crank pos censor, something is dicked up with it. Well, I go get another distributor and the shit still gives me the code. Checked all wires and all have resistance and the continuity goes all the way to the conector that goes into the ecu. What can this shit be? It happened after I did a compression test on my motor. I am getting really agravated with this project.
