Welcome Setupnet.  You have come to right place for advice and to source parts.

Welcome. Lots of folks here have great success sourcing parts. I replaced my fuel pump not long ago. PM me if you want the details.

How far did you have to travel to get there?

Welcome to the land of Ks too. As for $850......well, this forum will save you a bucket load of money, with knowledge and advice freely available. All you have to do is post your credit card details up here for 24 hours so we can buy beer to prove you are over 18!

In a serious note check the home page on what to do when have bought a K. There are a few things, you already met two of them, but not too many and when you have them sorted all will be fine. The injectors and fuel pump problem, along with one or two more, are likely as a result of sitting for a long time and bad petrol left go stale. All in all they are reliable bikes once the known things are sorted.

Before you put those injectors back on the bike; clean the tank. Replace the fuel hoses and clean the injector rail. Otherwise, you are just going to pump the gunk back into your injectors.

Ask me how I know .....

welcome setup

lets hope your problems are small ones

it isn't really hard at all ...some great information abounds the forum here

enjoy the experience

Fuel Injectors: http://classickbikes.com/ckb.tech/0.ckb.tech.files/fis/fis.htm

ok i got injectors ,mustang fuel pump,tank cleaned,new plugs new wires & coils ,strong spark, wont start.
Looks like somehow not injecting fuel . Starter kinda weak too .It did run after i put little gas in throttle body.What now HELP 

When you hit the starter button the fuel pump should run for 1.5 seconds . Does this happen?

please make sure that the battery is fully charged ....the starter relay is known for welding closed if the battery is low ....  just a heads up
