Engine Start-up!
This was planned for last night and I had a few friends over to help & hinder…
Having an electric waterpump makes filling & bleeding the system really easy, so this was quickly ticked off the list.
The fuel system was then jury-rigged from a jerry-can, but utilising the car’s HP pump, as at this stage I didn’t want to run the full system. The first issue we found was that that the ECU wasn’t running the HP pump, so this was then hot-wired straight to a battery, which made no difference. This was annoying, as it was a brand new Bosch pump. However a gentle clout with a hammer, it was running and the fuel system was primed.
Next issue we found that on cranking, there was no spark. 12V feeds to the coils & continuity checks back to the ECU seemed OK, so then we realised we hadn’t loaded the base map into the ECU, which still didn’t make any difference…..
We then started looking at the crank sensor. Pin-out checks were OK, but the ECU didn’t seem to be picking up a speed signal. After checking the sensor function & correct gap, we eventually came to the conclusion, that the sensor was not seeing a clean signal from the trigger wheel. Although the sensor is correctly aligned to the trigger disc, the steel of the TV damper is masking the flux generated between the sensor & tooth (see attached). Not a big problem, I just need to remove the damper and machine a recess next to the trigger wheel to allow the sensor to read a clean signal.
A bit of a set back and I wanted to get this behind me before I went on holiday this week – never mind, something to look forward to on my return.
