        So you still have a crank no start after charging the battery and cleaning the terminals?

          Correct. Charged & Cleaned up. I’ve also checked both fuse boxes for any burnt out fuses and they’re all good to go._x000D_

          I’m not liking where this is heading too. Oh boy! What’s next?

            Answering some of our questions on how you are exactly checking for spark and fuel will be a big help._x000D_

            Obviously either or both or missing and we need to know which one._x000D_

                I’ve sprayer starting fluid while trying to start it up & did the spark jump test you had in your videos. There is gas in the lines I’ve checked after changing the_x000D_
                pump. Not getting any spark at all. Took my ignition module off and had it tested. Not

                  If you’re not getting any spark, double check the power and grounds at the module. The module could test good, but if its not getting any power than you’re gonna have a no start. If all that checks out it pretty much has to be a crank sensor problem…. o

                    Don’t rule out the wiring harness from the crank sensor to the ignition module. Sometimes this harness will hit the rear exhaust manifold and short out causing no start. This is usually caused by a mechanic that didn’t route the harness right while servic

                      If spark is the problem I would check for the primary signal going to the ignition coil, that may not be easy on your set up however if you have the type with the coils that fasten directly to the ignition module.

                          I would also do a wiggle test of your engine bay harness._x000D_

                          I worked on a Chevy truck today with a similar setup. Crank no start. The problem ended up being the 2 wires going to the coil. If i wiggled them, the truck started, While it was running, if i t
