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

[mrgud]

Red Wrote:The schematic will be *necessary* to pin that one down. The EFI fuse goes to the EFI main relay but a failure downstream of that in all sorts of places could put voltage on that line. Fuel pump circuits, computer (if it was attached while the quarter was cut out, it might be damaged), fuel pump test connector or check engine connector if they were shorted out...it hurts to look at. Some time with an LED test light or multimeter is going to be the way to find out where that 10v is coming from.

As Ivan said, we measured between one pin and ground. One of the pins of the fuse had 12 and the other had 10V. In normal conditions one pin and ground should be 12V and the other pin and ground should be 0V. (that should clear my week explenation...)

Now, what do you mean by "downstream"? I don't dig electric circuts that well I have to check again...
What is the "direction" of the wireing? Batery, contact key lock, fuse, relay, ECU, dome check engine lamp... don't have the clue where further, probably the batery to close the circut... )


Today is the day, I am going for it... going to fire every single idea that I have...
Check the wire to and from the EFI fuse
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... )
Don't know... I am a bit mad and tired... I hate when things don't tur out as they are suposed to especialy after 4 days in a row, fireing every single idea in my head and going around the car as a cat around the hot porrige... You suspect of something, all happy, go for it, do it, and it is not that... moral crash... Oh well that's life...

I did a quick analasys...
Takumi blew his engine
Zax blew his one time...

Maybe this happens only to the true hachi masters (or plain dumbasses as my self )
