The tapping is gone in the radio and car runs great! Literally a 135 ft patch of rubber laid out in the street.
Went to the bone yard and picked up a couple of injectors and a trunk closer motor for $25. My guess is the injector was shorting out inside itself, causing the tapping and of course the lack of fuel dispersion.
The pulley cover (stamped steel) comes off with 2 or 3 bolts. You do NOT remove the water pump pulley. Remove the water pump tensioner and belt. Drain the coolant. Remove the water pump housing cover and thermostat hose assembly. DO NOT fool with the water pump drive pulley which is pressed onto the front intake cam snout.
The water pump assembly capsule is retained by tangs. You use a special socket and retainer strap (Auto Zone, Pep Boys, etc.) to rotate the entire capsule clockwise 1/4 turn and the whole damn thing comes out. Remember what the installed tang location is. Lubricate the new capsule seal with a tad of Vaseline and replace the new assembly and seal and rotate it counter clockwise to lock it into the housing. Replace the housing with a new seal ring/gasket and refill and bleed the system.
Finished the water pump finally, had to use one of those rubber strap type oil filter wrenches to hold the pulley tight enough to get it off. Flushed the system six ways to Sunday and all kinds of crap came out...hopefully I won't need a radiator soon.
Thanks guys for all your input, I really appreciated it
Now I've come back to the infamous E048 code (EGR Valve) and the E052 (Air control door). The car is blowing really hot air in the cabin. I know it's probably the vacuum line that controls it, but I can't find it.
Found the main cause of the climate door not working, all the vacuum lines in the car (under the hood) where dry rotted and nasty; car more than likely had vacuum leaks to boot. About thirty minutes and 6 feet of new vac line, the door now works...

Re: WTF is up with this Eldo?
Why are you concerned? The diaphragm is easy. Just put a hose on the nipple and suck. You should be able to feel the diaphragm draw up with a finger from underneath. Plug the hose with your tongue and it should hold vacuum. This is of coarse if you do not have a hand held vacuum pump. The solenoid is another story. I'd have to see the FSM to know how to do that.
