    Got the new circuit breaker installed and got the spark tester. Does it need to go to a cool or to a spark plug like I have it? Same deal, engine cranks but doesn't start. The spark tester is not lighting up when I crank it, but I clearly had fuel pressure yesterday. I tried swapping the crank sensor plugs too and no change.

        Just throwing this out there...but have you tried completely bypassing the safety lanyard switch? I've heard these sometimes go bad.

          I haven't tried bypassing the kill switch yet. Is there an easy way to get behind it without tearing off the whole side panel? The check engine light is on when I have my lanyard hooked up, and the light turns off when I pull the lanyard off.

              I found this 50 amp red push button fuse at the back of the engine near the ecm. It seems to be popped out and won't push back in, but seems more spring loaded than a normal fuse. Any way to test it?

                Is that middle fuse okay? It is hard to tell in the pic, but it might be burnt on the left side.

                Since you have power to things other than the starter, your safety lanyard is okay.

                  Those buttons are like that for all the ones I have seen. Makes one think, quite to your point....nothing is happening. A push will reset the breaker with no further indication of a reset.

                    I used a fuse tester for all of the three little blue 15 amp fuses and all checked out. So the red 50 amp push button fuse is okay then?

                      I would say yes, but the test would be to check for a closed (reset by the button) circuit across the breaker.

                      Once it resets, it should close and carry the load.

                        Based on what I have found, it must be one of:
                        -ignition module (https://www.mastercraft.com/teamtalk...t=70214&page=3)
                        -one of the 3 relays by the ecm (https://www.mastercraft.com/teamtalk...ad.php?t=66772)
                        -bad crank position sensor
                        Not sure how to troubleshoot any of these issues, other than using and ohm meter to check the resistance on the relays.

                          Question regarding the middle PVC piece. Does that fit the garden hose attachment off of the shelf or did you have to thread that?

                          Great idea, so over the whole bucket method.

                            It came threaded. I just went to the store and told the guy there to get me from 1 1/4 inch beaded end to garden hose connection. He did it in those 3 fittings.

                              Been out of town, but from what I gather he fuel pump is priming the system but you don't have spark. Call your local parts store and see if they can check an ignition module for a GM. Like a 98 Cadillac. They should be able to verify the condition of the ignition module. If it's bad you know what to buy. Of it's good then one of the crankshaft position sensors has gone bad. If you replace them make sure you check the gap between the sensor and the crank. If you only buy one just replace one and see if it will start. If it won't start replace the other one with the sensor you just took out.

                                I pulled the ignition module off tonight and will take it to advanced auto parts for testing tomorrow.
