Hey just signed up having problems with my 2002 gu zd30 the engine light keeps coming on.. the turbo seals went earlier in the year, got the turbo replaced and Nissan replace most of the sensors, I've blocked the egr, the engine light has started coming on again. I have a Dawes valve and boost gauge to be fitted this weekend , is there any other mods I should be doing ? Any help would be very helpful.
I went to download a manualbut can't as I'm to new to the site
Jack,
I doubt you'll get an answer till you head over to the introduction section and formally introduce yourself but Welcome to the forum.
Hi Jack dis connect to battery for a while see if that helps.
but in the mean time pop over as suggested to the intros
you will get a better response, I dont think the manual would help with this problem
Thanks , I'm still trying to figure out the forum and the etiquette
If you have blocked the egr you will get the check engine light but you should get it sorted by doing the daws valve and boost T .
Do you have gauges fitted???
I have blocked the egr , Dawes valve ,boost gauge.
I have done every thing that can be done as far as I know. I have cleaned the maf with maf cleaner
ok sounds like you need to disconnect the battery for half hr or so to reset the ecu and then it will be playing with the boost to make sure you are not overboosting the engine.
Battery is disconnected , and I went and got a new maf sensor , see how that will go.
Boost is set a 13 psi.
Might want to swap your ign relay [blue] with the aircon relay for a test[Blue]
Photo are in a thread with similar problems, also poor earths are a curse of all GQs and GUs
boost is a tad low IMO but all motors are different, would prefer it up another 2 or 3 lbs
ign relay is on the left
