i installed the walbro following the instructions of EVO MOTO. i followed them to the t. it went smoothly and took about an hour.

now the car wont start.

trouble shooting suggestions???

 

Are the wires on backwards? did you disconnect the battery before you did this? did you reconnect it? Disconnect the negative on the battery, and re-set the ECU. Maybe it detected you disconnected it. car wont turn over? or you have no power?

 

I followed those same instructions on my 8 and 9. Nothing wrong after install.

 

Could be a bad Walbro...I think there are a good percentage of ones shipped that are faulty. Do you hear it running?

 

i took it back out, and hooked it up to my RC truck battery (7.2V) the walbro works fine, i noticed that one of the wires was out of the harness that hooks to the underside of the harness that plugs into the whole pump housing, i replaced that wire, still not starting, will play with it some more.

 

and no i dont hear it, is it pretty audible when u turn the ignition on ? (my backseat is still out, so is the cover)

 

car turns over fine, there is some electrical issue with the wiring on the pump housing i believe. ill put the stock one in and see what happens.

 

bad pump or no fuel

 

did you pump the gas pedal while starting the car? if not try that. Also maybe you accidently yank of fthe black ground wire, takethe fuel pump back out and double check.

 

You probably hosed the wiring and blew a fuse, hows the fuel pump fuse looking?

 

yeah the black ground wire was out of the harness that runs from the top of the pump to the receiving harness on the outside of the pump housing. i put it in, i still dont hear the pump running. i eliminated the pump as a problem, i hooked it up to a battery and it runs.

 

i think its no power.

 

as long as you have it plugged in proper, and grounded or whatever it needs, i bet you flew the fuse.

 

fixed. thanks for the suggestions.

upon taking the pump back out, i noticed one of the wires in the harness had popped loose.
