I want test injectors spray pattern and I need to bridge fuel pump to have constant fuel flow.
I saw many times "bridge fuel pump relay..." but no one write how. In haynes manuals I cannot find fuel pump relay scheme.

So I must remove relay and put wire somwhere on white plastic thing where relay goes .

here is picture of relay, does anyone knows what I must bridge?

 

anybody ?

 

you dont bridge the relay itself, just the connector. look at the connector and which pin from the relay goes where, then bridge where pin 31 should be and where pin 54-15 (i think thats ment to be pin 87, but not worry) get a peice wire between those two connections and when you turn on the ignition you should hear the fuel pump go nuts! hope this helps.

 

You mean like this?


just do that on place where that relay goes...

Thanks !

 

would be easier to just disconnect the pump relay,get a piece of long enough wire and run it straight off the pump connection to the battery, job done! i did this the other day when i had a fault with my relay not working,all sorted now though.

 

yoe mean from + from battery to + on fuel pump? hmm...not bad idea but this is easyer because I dont have so long wire :/

 

get the yellow relay out the fuse box under the bonnet and plug that in the pump will run all the time with the ignition on!

 

thick black/red to thick black red

 

i done this once.couple of ways to do it.where the relay goes in to. i.e the base with the wires under it to simplify it.if you have test lamps when you put the ignition on there will be a live.make a small cable loop and put the live to another cable.cant remember which one tho as i havent looked at a base in ages.you should hear the pump.other way is as said above.from battery to pump but personally id do the first one.years ago i did it so its a bit vague.hope this helps atall mate

 

thanks...

I just didnt understand DAVE8OY, what to do when remove yelow relay? put yelow relay somewhere?
