Thanks,

I'm hoping I can get some help here. I've already downloaded some manuals from this site which have been very useful.  I don't mind paying $12 for a year. It would be well worth it to me to get some help. 

Hope I'm in the right place to post this. 

A neighbor of mine moved away recently and left his 1983 Yamaha XVZ12 with me. Hasn't been started in several years. When I turn the key on the fuel pump works for just a split second. The red light on the dash is always flashing. I'm assuming that shows a problem with something the main computer controls. I have ordered several relays from Ebay and replaced some that I know were bad. I have 3 of the fuel pump control units and according to the test procedure in one of the manuals they all test bad. When I leave it out none of the relays work but with it in one relay comes on and stays on but the fuel pump relay just comes on for a split second. I know the fuel pump works well because when I remove it and hook it up to 12 volts it pumps very well. I know at some point as much as I hate it I'm going to have to pull the carburetors and clean them. I'll have to ask for help on that too later. I've already replaced the fuel pressure sensor it was bad. Any advice would be very helpful. 

Thanks.

You should probably post this in the Watering hole. Not too many will see it in this forum.

And welcome, I'm sure there will be lots of help available and there are lots of articles to glean from.
