Yes, you've guessed it. Another My Zed wont start thread.

yeah, STEER CLEAR OF THERMOS!
Keep the factory clutch fan
Make sure its working properly
Ensure your Full shroud is fitted, including lower section

NOTHING compares with the CFM of the OEM clutch fan.

 

Is the clutch fan the one in the engine bay? and the thermos are the ones at the front of the radiator?

I have the fan with the shroud still in place with an upgraded Radiator.

 

Spoke to my mechanic and he thinks it could be the fuel regulator.
Does the fuel reglator have effect on the car starting?
Because the car does start just takes a while

 

Do you have a fuel pressure gauge you can use? I'd imagine that if anything were wrong with the regulator you'd see either too much or not enough fuel pressure as that's all it does.

 

I dont have a gauge for fuel pressure

I fiddled with the CTS plugs and now im getting code 55 but still not starting

 

Fixed.

Mine didn't get above 90 on the track, and usually floats between 75 and 85 in traffic. Fan is set to come on at 85, turn off at 75, off entirely over 80kph.

 

If you think the regulator may have a problem it may be worth trying to find someone with a fuel pressure gauge you can borrow.

I've not read the rest of your thread but if you have been having issues with the coolant temperature seosor you may well have been running very rich and ruined your spark plugs too. Now that you have rectified the CTS issue a new set of plugs may be all it takes.

As I said, I've not read the whole thread so tehre may be something there that makes all this info pointless.

 

Ok, tried something new today after i got sick of continuously jump starting it.

Today i got my friend to tow me up the driveway onto my street and we tried roll starting it. It started on the second drop of the clutch.

Does this help diagnose the problem fellas?

 

Also, i'm looking for some stock 2nd hand front and rear shocks. how much do they go for?

 

even a girl could tell you that ,buy a new battery and check your alternator voltage

 

Have you read the whole thread?

 

Change the CTS connector and clean the pins in the sensor itself. This will almost certainly be the problem.

 

I have changed the plug to one with zero corrosion already, what would you suggest to clean the pins on the sensor?

Thanks for the reply mate

 

I broke my ankle on saturday so sussing out the car problem has stopped. But before that happened I was starting the car by roll starting it. IT started first go and ran great, but then when swtiched off you would have to roll start it straight away, the battery wouldnt charge.

But when jumpstarting it it would take a long time to start, about 5-10 minutes. But when roll starting it it would start instantly.

 

Broken ankle? Ouch...

Just thinking out loud here.

So bumping it will work, but it wont start off batteries.
When bump starting an engine, your almost completely removing starter load from the equation, leaving almost all the battery reserve to send to ignition and injection. Im no auto leccy, but theory tells me that starter motors get first dibs on battery power, and whatever the starter doesnt use, gets sent to fuel/spark.

What sort of battery are you using to start the car? Are you using another battery to jump, or one of those dodgy starter packs (which turn to shit after 2 jumps). Dont rule out a dodgy jump pack or jump battery. You'll be chasing your tail forever when it might be shot batteries.

What im getting at here is the battery/jumper your using might not be giving enough grunt to turn it over quick enough. Ive had this same issue before (not in a Z though), where I could start it instantly off a bump, or jump, but never on the installed battery. This was solved with a bigger battery. You mentioned before that the lights dim on the dash. It could be as simple as trying a battery with a bigger CCA. If it sounds a bit laboured while turning over, this could be the problem.

Having said that, it would pay to test the alternator for charge, and test the installed battery for dead cells, to rule out the possibility, and also avoiding the issue repeating. I think someone mentioned this before though.

Earthing was also mentioned. A bad earth will produce exactly the same symptoms as a dodge battery. Check them before you think about the batteries though.

When the time comes, get a mate over to do a running jump. IE jump start your car off thiers, while thier car is running. This should provide enough juice. Also consider the amp rating of the leads you use. If they are rated less than 300, use 2 sets. Double leads sound shoddy, but believe me, it works.

If the batteries, earths and leads are good, and a running jump fails, Id bet my left one that the starter motor is shot. When they burn out, and/or are on the verge of dying, they draw too much current, giving the above symptoms.

Just throwing in some ideas/experience to think about while the ankle heals.
All the best with the break (and car)

 

As a follow up to what redzepplin said a bad cell or 2 in a dud battery canh cause even a good jumpstart situation to fail if conditions are bad enough, although a bump start is often a job here as well. I would seriously look at all your connections to the starter motor and earths and battery terminals. also can you confirm that there is good voltage in the battery.

My thoughts really tend towards your starter motor, when you bump start the car the only thing you take out of the equation fully is that. The starter motor is the single biggest drain on your battery, if the solenoid is gone it can cause issues, if the brushes are gone they will cause issues if the connections are gone it will cause issues. If someone has a good spare starter motor they are an easy swap try this as an option.

 

Thanks for the info guys, really appreciate it, ill have a go at it soon

Also, ever since I have had the car, there has been a very loud noise coming from the engine bay, to me it sounds like the big fan infront of the engine, (Clutch fan).

Just wondering if this is normal and if there is anyone who had the same problem and how did you fix it. Its pretty annoying when I can't hear the blow off valve over the fan sound lol.

Also, the sounds is always there, even on idle but gets louder and faster when you rev it, so guessing its the big fan. Its there all the time not just when its cold

But yes, i didnt have it in my previous Z, but that was NA.

Thanks

 

Anyone had this before?

 

Your in canberra...your zed has frozen solid...it's not going to start, wait until summer.

 

Haha thanks, but i was talking about the fan issue i have aswell
