THANKS Last edited by mike_vango; 06/02/08 03:28 PM.

They could then say find a sensor as the cause and swap it... eat the cost on a $50 part (mark up on the computer will cover that anyway) and charge you for the diagnostics check and computer.... Ask for the old computer. Retry it and verify it causes the trouble

Eventually the high voltage will make its way into the primary circuit and back to the pcm. This will anger the pcm gods and they will shut down the asd relay. The fix is to replace the coil, plugs & wires and maybe the pcm. If your mechanic has a scope, he should be able to see the high voltage spike leaking into the primary circuit.

You tell us how the PCM knows secondary voltage.

That era Dak/Ram/Van had an issue with a soldered connection in one of the power feeds under the fuseblock. The tip-off is no power to the injectors; a bad coil shouldn't affect that. Can cause an occasional no start issue. Free advice and worth every penny... Factory trained Slinky rewinder.........
