Change my fule pump in my 02 mitsubishi galant won't start

SOURCE: 2002 mitsubishi galant

Has it overheated lately?
My wife overheated our Galant and it just stopped working, it cranks but that's it.
I pulled the sparkplugs and found them wrapped in a gewey jelly like substance. Like an oil/antifreeze combo.
I am going to replace the entire motor for $1000 as taking it to the mechanics to theorize and practice may cost more.

Waterpump replacement requires removal and replacement of your timing belt. Because of this it is not your typical do it yourself repair. Engine timing is critical, and not having your belt set correctly can lead to catastrophic engine damage.

You can purchase a service manual at your local parts store to get an idea of what is involved, however this being an interference engine you should leave this job to a professional if you are uncertain enough about your abilities that you need to ask for help on it. The cost to replace the waterpump is far far less than the cost to repair a engine that had an incorrectly set timing belt.

Check the operation of the heater control valve. If it doesn't open up no heat. If the cable moves the control on the valve take the valve off and check it manually. The lever may work but the valve still doesn't open.
