Engine Start-up – Part 2!!
After the family holiday, I’ve spent a frustrating couple of weeks trying to start the engine. The TV damper was re-machined to give a cleaner signal to the crank sensor. This helped, but wiring the sensor the right way round made the biggest difference – doh!
After getting the ignition system firing, the next issue was the injectors. Due to a mis-communication with the ECU supplier, I’d got too many earths and no volts going to them!
With that resolved and the engine trying to start, it was clear that there was a firing order issue. Swopping coil leads around, was the answer, but as the coils are mounted on the back of the heads, sod’s law dictated that with the corrected firing order a couple of the leads were now too short, so a new set had to be ordered.
Just when we thought we’d cracked it and a truck battery supplementing the car’s battery (as we kept flattening it), we knackered the starter motor. Admittedly it had had a hard time over the last few weeks, but it was a brand new gear reduction one so very frustrating.
So after the new unit arrived, we finally had it started and idling, which is a major mo-jo boost. Next job is to finish putting the car back together and look at getting it to a local rolling road to sort out the calibration.
Regards,
Andy
