I have had some difficulty lately, specifically, the fuel pump not working (and of course the car not starting) without being attached to a 12 V battery bypass because it's not getting electricity from the battery, so the fuel pump is apparently in good condition.

It has behaved like this just during the summer when it's hot, mostly during the day and not at all at night or in the evening.

Now the car just won't start (93 del sol Si) and when trying to read codes from the ecu nothing happens, just a check engine light with no flashing.

So, I'm going to replace the ECU first, then the fuel pump relay and then finally the main relay. Does that sound like a good plan?

The car is also not getting any spark.

Thanks for your suggestions.
