I have a 2009, 59 reg 1.1 basic (ie no A/C etc) Panda.
Two weeks ago got in it & saw the dash lights all lit - even though I hadn't put the key in the ignition! Started car, all OK.
Later same day, wipers started up on their own, control stalk made no difference, stopped when I switched ignition off.
A few days later, got in, turned the key, lights up, immob light off, no response from starter. Changed battery for one I keep on trickle charge, still no response. Had similar prob with Punto, was engine earth lead, looked deteriorated, so jumped with a wire, fired up & started fine. Fitted new earth strap.
Few days later, engine refused to start, cranked over fine.
Checked - no spark, no fuel, pump off - immob light going out.
Tried easy start, spare coils no difference.
Checked pick-up ring, taped spare key into it, no difference.
Took off the engine ECU, checked internally - no evidence of anything wrong (I have a lot of experience with electrical repairs).
Checked as far as I could connections to the engine ECU, power, earth etc.
Hot-wired the fuel & ignition circuits, fuel pump coming on, still no spark, assume they're not being 'switched' by the ecu.
Took off Body computer to check, awkward to dismantle, checked fuses etc.
Immob light goes off after a few seconds, I assume this means that aspect is OK?
Now considering changing ecu's or sending off to be sorted - anyone advise which is most likely to be at fault?
Have seen ecu sets on 'auction site' - none of these exactly match the numbers on both units. Some match the engine ECU, some the body computer, is this a problem? Now close do the numbers need to be?
Is there a problem if the car they came off is different to mine eg A/c, 1.2 engine, front spots (been told this can shut down the body computer if it doesn't detect them?
Any help appreciated, thanks for reading, Merry Xmas!!
