Need Help!
I have a 2004 dyna wide glide fuel injected! I started the bike and it turned off and won’t start back up the fuel pump isn’t turning on I checked relays and pump fuse everything is working but it will not prime when you turn to run position.. I tried checking for codes it says no response and yes I have it on run position I also have a dyno jet tuner and I plug that in to try reading the ecm and it says no ecu detected! Has anyone ever had this happen??
Sounds like the fuel pump doesn't get 12 v power input.
Try to locate connector 141B and check
if pin A gets 12 vb power input from the fuse
if pin 87 from the relay gives 12 v output
Have you checked the ECM fuse? The power into the system relay comes from that fuse....
If you read 12 v at the output side of the fuse check if you have output at the connector to the fuel pump
If you read 12 v at the connector most likely your fuel pump is shot
If you do not read 12 v at the output side of the fuse put in a new one
If you do not read 12 v at the output side of the new fuse go to the input side of the fuse
If you read 12 v at the input side of the fuse and not at the output side could be caused by an interruption on the fuse board
If you do not read 12 v at the input side of the fuse could be caused by a damaged power line comming from the output side of the system relay; put in a new relay and check again
If you read 12 v at the output side of the fuse check if you have output at the connector to the fuel pump
If you read 12 v at the connector most likely your fuel pump is shot
If you do not read 12 v at the output side of the fuse put in a new one
