Battery has a full charge and connections all good? Did you check primary voltage at ignition coil, dark green wire with orange tracer. Engine cranking, that wire should be hot. I believe voltage for your fuel injectors, same colored wire. If you have problem with fuel injectors, did you get it straightened out? Your asd relay supplies voltage to several systems. Some of these, the computer has to see both the cam and crank sensor signals or it won't ground the asd relay. as far as removing crank sensor, I don't know any tricks. They give me problems, also, sometimes.

Yes battery is good as well as cables,.my power wire on my alternator has a crack in it and it's green but that wouldn't be the problem would it? Even tho it was running fine and the V were 13.5 while driving?
