Please, I need your help. I have a 1998 GMC k1500 z71. It was running perfect and then Sunday I turned it off,ran inside to grab something and now it just cranks. I'm getting 60psi of fuel. I'm getting 12 volts to the ignition control module and the coil. I replaced the distributor and the coil but still nothing coming out of the coil. I plugged in my scanner and there's no fault codes. It's not the security system. My battery was low because of cranking on it but I'm charging it up tonight. I can't figure out why I have no power coming out of my coil. I bought an oreilly coil and distributor so I know that they could be bad even tho they're new. That place sucks. I need this truck for work. Please please help me. I support you and watch all of your videos. Thank you for what you do!
