Can't fire up. Buzzing from the relay, lamps blinkin- HELP

"Now, what do you mean by "downstream"?"
DOwnstream, meaning anything that is further "down the river", i.e. further down the path of the flowing electricity, from the source (the battery) past the device, all the way to the ground/return connections.

"What is the "direction" of the wireing? " Traditionally, power from a battery is supposed to "flow" from the positive to the ground, thus the "downstream" metaphor. Which apparently didn't translate very smoothly, sorry. (According to modern physics, the electrons don't flow at all and the real flow is exactly the opposite but that's not going to help fix the car.<G&gt


"Check the wire to and from the EFI fuse"
If you got 12V on the supply side (terminal marked "3" I believe is the supply common to all the fuses in that fuse box) that's normal.

"Test the fuel pump (don't know how, but I'll try to find the power wires of it in the trunk and yust put 12V on it... ih it buzzes it works... I'll try to find something about it in the manual first... ) "
Next to the check engine connector (at least in the AE8x) is a fuel pump test connector, if you jump it, it supplies power to the fuel pump. Otherwise there are more controls that can get in the way. THe manual should give you the diagnostics for it.


"Don't know... I am a bit mad and tired"
That's not uncommon with electrical problems in cars. Garages don't get upset, they just replace whole systems until something gets fixed and then they try to tell you "That's the only way" so you have to pay for it all, needed or not. When I get the feeling that I've looked at everything and there's still no reason it doesn't work...I know it means I am tired and not seeing the real problem, I need to step back, take a break, and come back with fresh eyes. And recheck everything, even the very obvious things. Usually it is something very small, very obvious in hindsight, and I slap my head and go "Duh!" when I find it.<G>
