ISUZU RODEO SPARKS PLUGS CHANGE OVER

engine cylinder compression! (must be done WOT, wide open throttle even 1/2 open or readings WILL BE WRONG.
and all sparks remove for full starter RPM (speed)

so easy, you forgot to say all 6 are less than half normal.
answer cam belt slipped or snapped
as all do at our about 60,000 miles,
its a normal standard service point,
skipped i bet./

You have to remove the coil packs and the plugs are down in them holes. 6 coil packs 3 on the left driver side of engine 3 on the other side. 3 square black blocks/each side. Take screw out, pull up on the block. A tube will slide out the hole with it. Spark plug in hole.

That's a tough one! If you need routine maintenance parts like an air filter, oil filter or spark plugs just remove the part and write down the number on the part and get the same part number. If you need stuff like a starter, water pump, etc. you need to look for some kind of ID plate on the engine. Are you sure there is a Chevy engine in an Isuzu Rodeo???? Can't imagine how they did that!

check the coil, as it sounds like that may be the problem

In the drivers side head towards the front of engine. See myisuzuparts.com

its have a bad idle too? verify sparks plugs, catalytic converter and the flow meter. Have a check engine light on?? Do an ecu scan

it cold e the rings on your pistons not allowing compression cause it was lying in one position all the time i would clean plugs and spray a little oil into cylinders this will increase compression slightly and she might fire once she runs she will be okay then

not easy even if u can findum-if ur havin ignition problems try changin the plug wires n dist cap cause plugs r made tuff these daze or just take one out for inspection--also ign modules wear out also

This could be a problem with the spark plug wires. If resistance is high or the boots have carbon tracks, they could be causing spark to go places it shouldn't. Distributor cap?
Make sure places like that are clean and dry. Check for grease or dirt inside spark plug boots. If all else fails, open the hood in the dark and look for sparks jumping around the engine when you rev it up. If so, replace the plug wires.

Thnaks for the thoughts. I appreciate it.
