Default CKRA Motor Swap; Fuel Pump Not Turning On: Code: B103E

This was posted in the new user section of Ross-Tech (I don't have a registered user, yet) about 12 hours ago but no response yet. I'll try here too.

Long story short, I swapped the motor on my 2014 Passat TDI due to a timing failure that caused all of the rockers to break and bent valves.

I have the new motor in now and ready to go. New filters and fluids are in. Quadruple checked all of the lines and ground and everything seems good.

I am trying to prime the pump to get all of the air out of the lines and fuel ready to go. It's the last thing now before I can attempt to crank it. I can't seem to get the pumps to turn on. I noticed that my fuel gauge does not move and it shows empty. I know I have at least half a tank of diesel in there. I keep getting the code B103E. I wonder if that has anything to do. Maybe a bad sensor? Thoughts? Would a bad sensor cause the fuel pump not to start?

When I did hook the battery up to the charger, the positive and negative wires touched for a second, which blew a fuse. I replaced the fuse. All fuses are good now. Could blowing the fuse blown something with the fuel pump too?

Thoughts? Any help would greatly be appreciated!

Fyi, the car is currently on jack stands with the front wheels off and the front bumper off as well, which is why the other codes come up.

Try to jump the lift pump (in-tank fuel pump) directly with 12v. Just to see if the pump can operate.

I have not worked on my 2015 TDi's fuel pump, but I have worked on several other VW fuel pumps. Giving 12 volts and hearing it work allows you to troubleshoot more effectively. (Four wires are usual: two for power, two for float sensor. The outside pair are the usual pump power wires.)

It should be pretty simple to just lift the rear seat and access the pump cover.

After that...relay and/or fuse.

Okay so the lift pump turns on when I directly connected it to 12v.

While disconnected, I decided to test the power coming into the connector to the pump as well to make sure there wasnít any power issues coming in. With the ignition on, and in vcds priming the pump, there is 9v power coming in to the connector.

Checked fuses and the fuses and relays are all fine.

I decided to disconnect the fuel level sender. I then connected the lift pump without the level sender on and tried to run it since power is good going to it. It wouldnít turn on.

The pump is good and turns on itís own. Could it be a bad sensor causing it not to turn on when connected to the car?

On my way to go pick up a fuel level sender from the dealer to install to see if that changes anything.

Thoughts?

You can disconnect it and take it off separately. I know because I took mine off and just picked one up.

My pump is fine so the level sensor is all I needed.

$120 at the dealer. I was okay with paying that because I wanted it now.

Update:

I put the new level sensor on it but kept the lift pump outside the tank because I didnít want to get the new sensor dirty in the event it didnít work and I could just return it. I plugged the connector on it to see if I could get it to start and clear the code. Still nothing.

So I decided to put the old sensor back on, put the lift pump back into the tank and plug it back in. I manually, with the 12v battery, turned the pump on for a few minutes to get fuel flowing.

At this point I figured Iíd try to crank it.

Immediately when trying to crank it, the fuel gauge switched on and the lift pump turned on its own the second I pushed the on button.

I could now activate the pump through VCDS.

Weird that it wouldnít before trying to crank it.

I cleared the code and it went away!

I then bled the injectors and the car started right away!

All is good now.

I still find it weird that I couldnít turn the pump on before but oh well, it works now!

Congrats on getting that all put together. Do you have any idea how your timing was off on the timing belt change that frag'ed your original motor? It sounds like you have some mechanical talent changing out your engine, so it's somewhat of a confidence killer for shade tree mechanics thinking of doing their own timing belt replacement.
