Fuel pump does not receive fire

I own a 2004 Fat Boy Fuel Injection model and put a new fuel pump on because one day I went to turn it on and it rolls over but doesn't start. And as I said the fuel pump does not receive fire but everything else does lights, horn etc. What can cause this?

Oh Boy, On late model vehicles with fuel injection, You have a low engine oil sensor, if more than 1 quart low will disable ignition and a fuel pump relay(20 amp or better) if its bad fuel pump will not run (no fuel) In a no spark condition Always start with cheapest parts first, Check oil, check fuses and related electrical apparatus. I bet that fuel pump was expensive and it was probably OK. It would not be a bad idea to check the OBDII for stored faults. That always helps avoid buying un needed parts.

2004 fat boy won't start


First check for spark by using a known good plug and laying it on cylinder head while cranking. Leave the original plugs in. Do NOT remove them for this test. If no spark then either crankshaft position sensor or the ECU or the coil or system relay or fuses or wiring is faulty. If you do not have good electrical knowledge to check these out, bring it to a dealer. If good spark, then fuel must be the problem. Check to see if fuel pump runs for a few seconds when turning bike on. You shoud hear the pump running for a few seconds then stop. If the pump does not run, check system relay and fuel pump fuses. Note - the pump will only run once when turned on/off every few seconds. Bike needs to be off for at least ten seconds for next pump cycle. Check to see if faults codes are stored in ECU memory as these may lead you to the cause.

Hey there boatright33,

A few things things immediately come to mind.

There may be a problem with the engine controller. You could check the ODBII onboard diagnostics. Auto part stores will usually do this for you at no cost.

When you pulled the ones that were/went bad, how did the filters look? Could there be particulate matter still in the tank causing them to fail.

I always put this one off until last. Check the injectors. Are they gummed up?

Let me know what you find out
