Hello there,
Recently i had quite a bad experience with my Volvo and i had to get towed home from the supermarket.
It appears that the problem could very well be the fuel pump relay. This is not really a relay alone though it is a controller of sorts. It has a relay in it, but also a complicated circuit that decides when to turn the relay on and off and is signaled by the ECU.
What i really need is a schematic. I've been going nuts the past several days trying to draw a schematic by tracing out the board but it's very difficult because there are many SMD parts and some of the traces go under the IC chip which is also a 16 pin SMD part so i cant see under the chip.
The part number is 9434225.
Any ideas would be great. I've already spent hours on this trying to draw up the schematic and still have hours to go.
I didnt want to buy a new one yet they are rather pricey but also wanted to try to find out exactly what was wrong so i know what it was. I already found a few design flaws, but they are not the cause of this problem.
