Spark Plug and wire replacement

I tried the methods on here to pull the motor forward and get to the plugs from above but found it nearly impossible after following all the instructions to do it that way but found I had to go underneath the van to get to the plugs and you could actually see the wires but hard to pull off I had to use a long needle nose pliers and small screwdriver to dig out the broken end. ect.
I did pull off the fans and everything to get the moter forward but even if you do go underneath I dont think you need to do anything but if you do pull the motor forward it doesn't have to be enough to remove the fans. Just the air cleaner and such not to break anything. Good Luck it is somewhat of an accomplishment once you do it. Not at all fun. I found one fouled plug and after replacing the module, coil pak and plugs and wires it still misses. I am sure it is the injector now from seeing the one fouled plug from the back of the engine. Like the guy at the parts store said "thats all thats left" :(

Chevron Techron Fuel system cleaner. Empty tank, add 12 gallons, add Techron, run to empty, repeat. Works for me.

i did my back plugwires and plugs from underneath not real bad of a job.

I am trying to go from underneath. I am using a swivel connected between the spark plug socket and the rachet, but can't get enough leverage to get the old plugs loose. Any tricks or advice will be appreciated.

If you can get a stethiscope try to listen to the injector while the engine is running, you should here it clicking, also use a noid light on the electrical connector to see if you are getting voltage to the injector.

BE CAREFUL of moving parts when working around a running engine !

If those are good try listening for a vacuum leak, whistling sound, in that area or do a vacuum test.

Also do a compression test on the cyclinder.

Just some avenues to explore.

What kind of extensions do you have? I did mine this way and I think the swivel is what is needed, but also you might want to get a couple of different sized extensions. This will allow you to maybe put a small extension between the socket and swivel and then another extension off of that to get you out in the open, for turning. You have to get both arms up there to get them loose.

i don't think i used a swivel when i done my plugs..i used a 3" extension and you have to bump the ratchet handle with one hand and steady it with the other hand.one arm up by the exhaust pipe ,the other arm up by the inner tie rod on the rack and pinion .once you bump the plug loose then use the arm by the exhaust to finish loosening the plugs. do one plug at a time so you won't mix up the plug wires.a swivel sometimes makes it worse as you loose control of the ratchet.
