Why don't I have spark? In most cases, it is usually due to a bad ground or no ground at all. Check all connections. Here are a few things you could check: make sure the ground wire is securely attached; that there is no paint under the ground wire; the connectors have good secure connections; there are no breaks in the wires; the battery is fully charged. Check for a bad on/off switch to the ignition box. You could have a bad coil, and switching it out for a coil that you know is good is the fastest way to determine whether a coil is the culprit. Perhaps you have a bad triggering device. Check it by removing the spark plugs (leaving the spark plug wires on), and grounding them to the engine. Next: clip the two green trigger wires coming out of the engine, and repeatedly touch the 2 wires going to the ignition box together. Make sure the power to your ignition is on. You should get a spark, or the L.E.D. (if equipped on your MSD box) should light. If you get a spark, then the trigger is bad. If the L.E.D. light turns on and there is no spark - then either you have a bad coil, a bad spark plug wire(s), or a bad spark plug(s). Check your large red wire to msd box. This should be hot all the time. The small red to the box should be hot only with key on.
