You originally said fuel sensors, not fuel pump.

Output wire from sam to FUEL GUAGE.

I never mentioned pump??

I completely understand the two from the sensors to the sam
that’s a big help for me

i just really need to find out now what wire is to fuel guage from sam

as I understand sam reads both readings and sends a average to cluster

Why is it that you refuse to take readings on wires 27-33-40, with the key off and then the key on?

Oh so it’s can to the cluster that ruins that idea then, I was going to test by joining a sender wire to it

I was seing around 38. And 39. At the two Sensor wires at the sam engine running didn’t do a key off

to be honest didn’t test the other wire that’s Earth isn’t it?

i fully appreciate my lack of know how and I do apologise but im
here to learn

I'm totally confused with 38 & 39. What do you mean by this?

What does this crap mean, what is bba? Don't use terms that only you understand.
