Hi guys,

Enginr started fine this morning. As I pulled in to work, the svs light came on. Pulled over and parked. Turned the engine off. Then tried to turn it on again. Cranks strongly but won't start. I left it for a few hours, and when I came back it started fine. Turned it off again, tried to start again, but same issue as before. Any ideas?

Could be a number of issues causing that but for some reason I'm thinking a sensor.. Will need a scan gauge to find exactly what one not like the older cars thay you actually had to work it out yourself..

Sounds like your crank-angle senor is dirty and getting hot. It's down the front of the engine right near the crank pulley. Will have wiring coming from a connector. unplug and unbolt the housing of the sensor from the block. Give it a good clean up with metho, and whack it back in, connect the plug up and go for a drive, if it still does it, get a new sensor.
If you need give me a call 0439078594. :mrgreen:

Turned out to be a faulty sensor. Replaced and reading correctly. Thanks Olfart

Sorry, no. Pretty sure it was dead cheap to replace though

The exhaust return valve went on mine, easy to replace. Have replaced all sensors except crank angle. Mine is an old DMAX/Rodeo.

New air cleaner usually adds a bit of life, as we live on a dirt road.

Had a lot of trouble with a belt squealing despite having alternator out as far as it would go, so I ground out the swing arm thingy on the alternator, which gave it an extra few mm play to further tighten the belt. Problem solved.

Mine started out the same as jedis,drove it stopped then tried to restart it straight after I turned it off but no start just crank, then an hour later started again .went like this for a day or two and no start now.svs light came on but was running ok when it was running.can start it up with start ya bastard for a few sec.changed glow plugs cleaned all sensors,but no codes.orderd a Foxwell 310pro to check for bcm codes as my little one checks only ecm .first when started to play up got a maf sensor code.cleaned it with maf cleaner but no code since.thinking about to replace maf anyway.
Mat is your rodeo has the same engine 4jj1? Might check that valve out tomorrow.should be easy as ended up buying a full workshop manual 6000+ pages for dmax/Colorado/rodeo.
If anyone needs a copy can arrange it onto a memo stick

Yep, same motor.

Look at that exhaust return valve while someone operates the throttle.

MAP sensor springs to mind

mass air flow sensor ????
or scv valve maybe ???
bought a scan gauge of ebay a couple of months ago live reading on the dash and warning for fault also can clear faults
pretty user friendly about 100 bucks

Cheers
