Tried the relay wiring on the fuel pump.
The original wire is at 10v.
So I created a 12.1 v feed.
87 earth
85 with fuze to 12.1 v feed.
86 To the bosch 044 fuel pump
30 from the trigger.
I did this and the 25a fuze from the trigger near the yellow relay at the front gets hot and blows without the car working at all.

I quickly rewired it as it was wich was easy and it fired up.

Why would the 25amp fuze at the front of the car under the passenger footwell blow.
I rewired it direct to the battery and it still blew

 

that isn't how you wire a relay that's why you are having issues


here's an annoying american chap with an explanation

 

Good stuff.
I went on a relay site and took the instructons of there .
I will have another look .
Could you give the correct directions for now.
Ive been at this since 7.30 and got no were.
I had a view.
He does it totally different.
wow .
Have to say thankyou but the vid bloke is dire .
Well its sorted 12.2v at the pump.
I went the American way and also changed the relay.
I have lost my fuel sender on the fuel guage though unless I am on empty.
will go and fill up and report back.

 

well wish I hadn't put £15 in as I ended taking fuel tank of to get the sender wires on.
I didn't need to in hindsight but it ended up that way as I had a load of fuel in the tank.
I've emptied tank so all is safe.
I will replace it tmz and put a small amount of fuel in to test her out.
just short of 12 hrs to put an extra 2.2 volts to a fuel pump.
It was one of those electrical dayz were I tidied all I saw and put soldier on rough connections and heatshrinked a lot of stuff.
So there will be a lot of stuff that has been corrected as well.
The car is having it's stereo in tomorrow so i'm soldiering and heatshrink head tmz as well.
