Ls1 fuel pump

[timc83]

hi guys, I purchased a cheap ls1 wh, drove it for a few km, turned it off, then it would not start, couldn't hear fuel pump so I checked relays and fuses all ok. Replaced fuel pump still no go, check and found no voltage getting to pump. Rechecked fuses and swapped relays, still no go. Tried bridging out fuel pump relay, still will not pump... im stuck guys, any help would be great. Cheers

is there power at the relay? if not run a wire from battery positive to fuel pump pin.

 

[timc83]

Yes it has power at relay, that's what's got me stumped....

 

[Bob33]

thats a bit wierd. you'd have to say its a broken wire between the fuel pump and relay. if you can get a long enough piece of wire stick one end in the pin at the relay and try to back probe the connector at the fuel pump with the other end.

I know it makes no sense, strange it drove very well for about 300km, stoped and starrted half a dozen times all ok. Let sit for 3 hours then nothing!!!

 

[Bob33]

are you 100% there is no power at the pump when you jump the relay.
I've got to ask because thats just odd

 

[timc83]

Yeah mate, 100% sure....

 

[Bob33]

given that its got to be a broken wire.

 

[timc83]

Yeah, that's my conclusion as well, oh well, goodbye money, hello auto sparky!
