Good day to all Troopers,

*ts- i own a 2008 dmax. i had that too 2 weeks ago. what i did was drain the fuel from the water seperator valve at the hood. did it a few times.

everything is fine now.

by the way. another symptom. if in the morning you start your engine and you hear a clatter in the engine before it runs fine in warmup then there is air in your fuel system. and so bleeding it is what made my dmax run fine.

hope this helps.

update on this problem with check engine light and losing power. just sent my dmax yesterday to the casa. and the tech2 reported problem with the SCV/ suction control valve. replacement for the "modified" scv is P7990 ouch.

not sure if its a denso unit. but all 2010 and up isuzu crdi, the SA said, is using that kind of modified scv. the reason was dirty fuel. thats why its adviced to change fuel filter every 20000 kms.
