Now (no worries about the heat outside 30C+) I had a look again at the plywoodracer.
„Rebuild“ the fusebox and now to the back.
Measure the fuelrelais.
WP31 12.6V, W38 2.6V and W38 0.06V and black: clear, 0V
also a look at the fuelpump.
Measure W38 to W38 for „Ohm“… a „beep“= no problems.
W38 0.0V, GB29 0.3V, SG30 5.0V, black: clear, 0V
Than a look at the engine for the highpresure pump.
GW (green/prurple?) 2.6V, NY52 (yellow/?) 12.6V
So, is there a problem about the relais (40,-EURs) or is there another problem?
How can I disconnect a fuelline for a test?
The next week turns a little hot. Up to 40C…
