I have a 1994 pace arrow onan. Marquis 7000 model 7nhmfa26105d. The fuel pump was replaced by previous owner. I traced the wires to make sure he had it hooked up right when I wasn't getting fuel. Found blown fuse and it blows as soon as you start it up. The positive wire has a few splices in it. Any help would be appreciated.

Disconnect the fuel pump and replace the fuse. Then try and start it. That will
Let you know if the fuel pump is the problem.

detach the 12 volt supply wire. at its source and the fuel pump.
install a fuse in it, test for shorts using an ohms meter. if it shows ground replace the wire. if not, hook it up at the source, it should not blow the fuse.

run a separate wire with a fuse to the fuel pump. if it blows, the pump is shorted.
its one or the other

AZPete,
I have EXACTLY the same issue.

Here's what I've done.
1. I disconnected the auto choke - BLEW FUSE! then reconnected
2. I disconnected the positive Terminal of pump - DID NOT BLOW FUSE
3. I disconnected the other side of the fuse and did an OHM test between where the fuse connects to the power source & to the positive wire of the pump. - GOOD CONTINUITY, NO SHORT
4. I did an Ohm test across the pump terminals and the multi meter showed 1 before touching both terminals 0 when I touched both

Ok so If I have read this correctly I need to replace the pump. What do you think?

Thanks
