Hi Scotty, I have a 2008 Toyota hilux 3l Diesel and I have some issues with it . It doesn’t start right ...strange vibration and noise..has trouble starting without pressing gas pedal or when it won’t start, priming pump!
it seems like there is low fuel pressure as I have to press the priming pump so that it starts. Changed the fuel pump but no luck. No codes recorded. It also gives off lots of white grayish smoke on startup and when accelerating... sometimes after the engine is running for a good 1 hour, it won’t turn on again without pressing priming pump ...Turns over just fine
Thanks.
All the best from your fan living on the island of Mauritius
Check compression. The fuel can help seal the rings thus improving compression so it'll start. Check glow plugs for good measure and while your at it/there.
- Wow! Island of Maritius! What a cool place - we would all be lucky to visit there someday. Based on your symptoms it could be quite a few things. My first thought was maybe the glow plug (until I read that you live in Maritius). Have you checked the fuel filter? Has the oil been changed regularly?

Dang! I missed that one! (glow plug)
I think he's just gonna have to pay us a service call to come check it out for him ; )
note to self...read every word!
The only reason it stood out is because oddly enough I've spent some off time studying the island. It has the 3rd fastest growing economy in Africa and is off the coast of Ruinion Island (uninhabited) which is in between Maritius and Madagascar. Pictures are beautiful - would move there in a heartbeat - perhaps you and I can be traveling mobile mechanics (=
Could also be a timing issue.
If the injector pump is the metering pump (not common rail), then it has to be bolted on in exactly the right rotation. Like timing with a distributor on a petrol engine, but I doubt you can do it by ear, and certainly not with a strobe. You need a micrometer dial gauge and the correct setting for the pump model and engine.
Also the timing belt. I once had the idler bearing seize and the belt jumped one tooth, so put the diesel timing out. It pumped out grey, stinky, waxy smoke and ran like a dog. I thought it feels like a petrol car with the timing out, but didn't immediately consider that diesels have timing too. A new timing belt kit and waterpump fixed that. Shortly thereafter the injector pump sprang a leak, so that was reconditioned too. So both aspects of timing now good, and fuel economy better by 1 litre per 100 kms, an improvement of 8% or 9%.
