Greetings: After hours of frustration and lossing my tools into the bottomless pit of a engine compartment I gave up. I could not remove the air pump bracket on to allow the pump to pass over the stud. What was i missing here the manual and instructions does not really give you a clue as to what to do in a sequence. Can you ellabrate more on this. Anyway what is the standard cost to R & R the pump and tuneup the distributor including plug wire replacement and new sparkplugs. The vehicle has 94K and I would assume will need all the above since it is still running fine on the factory equipment. Thank you for your help but I have skinned hands and a broken ego on this job. the vehicle is all back together and driveable and rady to go to the repair shop.

 

Regards,

Bill

This is not an easy vehicle for a novice to work on.This particular job is just about a must to be done from the bottom.Remove the air pump from the bracket first.

What is the typical cost to have it all done by a good shop including spark plug replacement and wires. I will supply all the parts. Thank you.

Replacing the plugs on this vehicle is 4.0 hrs

replacing the distributor & water pump is 3.5 hrs.
