Volvo G720B has gremlins

mardi 29 juillet 2014

Greetings from sunny South Africa...

I hope someone can maybe help me with an issue we are having with our Volvo G720B - it has gremlins...



It goes through phases where it just won't start, but changing a fuel filter or disconnecting the batteries for about an hour sometimes helps - but I think it might be co-incidence.



Here's what it does....

It'll swing sometimes slowly sometimes at normal speed and just not fire.



Depending on the grader's mood various things are noticed when it won't start.



This time - there is no power going to the injectors and there is a fault code about general ECU failure

the last time it did this we disconnected the batteries for 2 days, cleaned every plug on the machine and changed the fuel filters - that worked



The last time - the diesel was just running through the fuel pipes not pulsing - changed the fuel filters, disconnected the batteries and it came right



But this time we are not having any luck on the usual tricks - any suggestions please!!!!:)
