This is a weierd one. This weekend we take the boat out (454 PCM) it starts up Idles perfectly revvs fine in nuetral. But when you put a load on it it never seems to kick in the secondaries!!! Here is a list of things I have tried already
1. Spark plugs and wires
2. Timing
3. Vacumn test
4. Carb adjustments
5. Distributor cap and rotor
6. Cylinder pressure test (though a valve might be sticking)
7. Check all wiring (including firing order)
I am at a loss if any one has a 454 (only has 344 hours on it) that has experienced the same thing please let me know
