Hi!

I have a 2005 Volvo Penta GXi-EF with about 430 hours on the clock. When trying to start it up, it cranks over fine but doesnt fire. I get 1 beep when turning the ignition on, the fuel pump does NOT prime and there is no spark.

I have checked the safety lanyard or whatever its called.
Oil Pressure Sensor
Fuel pressure relay (Also hotwired pump and it seems to be sounding OK) Bridged under relay on pin 30 and I think 87(?).
Changed the box with circuit breakers on top of the engine and put in new relays and circuit breakers.
New battery

Running out of ideas, does anyone have any pointers?

Considering trying and changing the crankshaft and camshaft sensor but they are very expensive.

Thanks in advance!
