Thank you Robert for your reply.

Nice to hear that ECU failure would not be intermittent. Anyway there's a threat that it will fail someday, so you can call it preventive maintenance. If it's all about replacing some low-cost components (like transistors, capacitors, coils etc.) on a PCB, why not?

Regarding the fuel pump relay, the last time I resoldered it was yesterday, usually I tend to do it twice a year or so. Replacing the crank sensor would be my next action - all that keeps me from doing this job now is a nasty placement of the sensor behind the engine, I cannot even see it.

BTW, the previous owner was crazy enough to eliminate the 25-amp fuse and simply solder that connection together. What circuits should it protect, that are not protected by other fuses?
