Can pulling the plug wires kill the coil?
I probably have bigger problems than this….
Blew a coolant hose and now have combustion gas in the radiator! Overheats.
Anyway, V-6, 1994, 111k miles, runs great so I removed all the plugs for the first time ever to try to find out which cylinder had the blown gasket or head crack. Sprayed hemi holes with lube and let them sit for a few hours and got plugs out w/o incident. Because of the WD-40, plugs came out drenched in lube and couldn’t tell if any plugs were wet. Put plugs back and started engine. Pulled each plug wire and none were misfiring. Engine is still running fine and isn’t even warm yet.
Then I pulled the dipstick just to make sure there wasn’t water in the oil. There wasn’t.
Then the engine quits like someone turned off the key. No sputter. Just stopped. All wires were attached and motor was running great at the time.
Removed #2 plug and find no spark.
Could removing the plug wires, one at a time, like I did, fry the coil? It didn’t happen when I was pulling the plug wires; I had already finished and it happened a few seconds later. If so, what part did I fry? The ignition coil in the dist? Or something else? Checked all the fuses and they look okay.
How do you safely do a compression check, which was my next move?
Anyone interested in a slightly used 18 year old LS 5 speed with a blown head that ran great until it didn’t?
Any advice is appreciated.
