Pull wires of plugs and put in spark plug tester and check for spark, if good spark, good coil pack. (note: Contrary to popular belief, the spark does not have to be blue, it will still ignite gas if orange) If you don't have tester, be VERY VERY careful and use a spark plug and just rest the side on the block of engine. I DO NOT ADVISE DOING THIS UNLESS YOU KNOW WHAT YOU ARE DOING, it send very very high voltage through and it does not feel very good to get zapped, trust me, i know.
Yes it will bolt right up to it.
The fuel lines around the filter; you will need an adapter.

Don't know what year you have but some sensors are temperature sensitive and you should run a 195 degree thermostat.

There is one before and one after the catalytic converter.
I have a '90 so I think it would be the same, on mine it is at the front of the engine on the bottom pulley. (crankshaft pulley or vibration dampener) To view the scale and mark I have to look down, a little on the drivers side of center. Beside the break resivour is a good viewpoint, looking just over the timing light. I have to run the timing pickup coil in through the drivers door or window and into the open doghouse cover. Good luck. God Bless!
The EGR valve on your Astrovan is on the backside of the intake manifold just under the throttle body attached by two bolts. After installing a new gasket be sure and torque the BOLTS to 17-18ft lbs or the NUTS (if yours has studs) to 15ft lbs)
There is no adjustment required, but you can clean it with a carb cleaner.
