Leaking spark plug well seals are a pretty common issue on the 2000-2002 LS's.
Since that coil is near the firewall, it could be moisture due to the location
of the cowl and possible lack of sealant on the coil covers, but that would be
very intermittant as the heat of the head would boil off the water after driving
post-rain or car washes. If you find oil on the coil(s), you will want to
consider replacing the valve cover gaskets and at least that particular coil.
You may find replacing the valve cover gaskets on the V8 to be easier than the
thermostat. so if the voltage is low! check the coils out. they may need changing.
Remove the plastic engine cover that covers the valve covers and ignition coils by turning the four quick-disconnect fasteners, located in the corners of the cover, using a screwdriver. Lift the cover up and off the engine. Lay the cover aside. Remove the electrical connector from the coil by pinching the pocking tab with your thumb and index finger as you slide the connector off the coil. Remove the 7 mm retaining screw that attaches the coil to the valve cover. Lift the coil out of the valve cover by twisting the coil as you pull off the spark plug and valve cover.
Replace the spark plug at this time if you are performing a tune-up in addition to a coil replacement. this is for a 2001, but the procedures are the same. from 2000 to 2004. GOOD-DAY !
Coils and plugs are new with no oil in well. The harness that plugs into the 4 coils on bank 2 only have 1.5-2 volts . The harnes on bank one all the plugs have 11-14 volts.
Check the harness, you may have popped a fusible link for that coil. Make sure you check the fuse block under the hood first as there is a seperate fuse for each side.
Will do! that was my next step but I had to find a diagram so i would know what fuse was what. would you happen to know what the "ignition Transformer capacitor" is. Looks like it's on the back of the head where the coil harness goes out according to this diagram i found. There are 2 so i guess one for each bank of coils.
dont have a picture of them. but they are for the coils on each side.
Well the transformers checked the same and i swaped sides with them and cleaned the grounds. Still same results. Any idea what is telling the coils to fire and where that connection is made. i have better than 14 volts on one side of coil harness plug and I'm thinking the other wire isn't completeing the circut.
check the wiring harness, on #2 bank. this is a problem on these engines and there is no good fix!
Took valve cover off after hearing a small pop or 2 come back through the intake .Secondary chain tensioner has spring pressure on the chain but I can push it down completely with my hand. Should these tensioners have the check valve or ratchet function to keep them tight once pumped up by the oil pressure.
do not have any info on the hydralic cam chain, but if you think that you are ok by taking other valve cover off to make sure. or you can call a dealership to find if its supposed to be tight. SORRY !
OK will do. Thanks for all your help. I'll let you know the results if i can get the parts and get them installed.
the cam chain should have some play in it but not a lot!

Observe the scan tool CMP Desired, Actual, and Angle Variance parameters before a DTC sets. This may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

I'm sorry but when dealing with these problems your best bet is to take your vehicle to a qualified repair shop , I have never see a DIY'ER correct the problem with these , an in the end always end up taking it to the dealer .
