Rocket won't fly.

Fuel pump is not working no juice to it. went ahead and replaced fuel filter. Pumps when jumped from battery but ECM doesn't feed it. Fuse is good for Engine, wonder what else to check? can I get by with a switch to run pump? Ya think? I'm not too familiar with Tune Boy yet but when I hooked it up for diagnostics on the fuel, it said NO.
ALSO CURIOUS Has any one else had problems with the final output bearing on their rocket but me? That is the flimsiest cage I've ever seen on a bearing that size. I replaced it with a turbine engine bearing and have 5k on that and seems OK.

Check the wiring scemes in the manual for where your problem could originate.

I just looked at the manual and your fuel pump relay is where I'd start. Sounds like the relay isn't picking up.

If it is the relay, sometimes a simple remove/replace will get them working. If not, your local NAPA may very well have a replacement. Bishop's sig line has a link to a manual if you need it.
Output bearing failure is a way too frequent occurrence on the Rockets. Do a search and you'll find threads, polls, etc. You ought to post your bearing findings in its own thread for the good of the collective.

Good Luck and welcome to the forum.

Thanks Atomsplitter that is two of you who agree. I hadn't even considered that there was a fuel pump relay!
