My Z is 1990 TT SWB Manual.

 

I went out to my zed last night and it wouldnt start. The starter turns the engine over and over but it doesnt catch. (The starter has a habit of just grinding on its own sometimes but thats another story.)

 

Checked fuses and connectors (had history of connector problems) still no joy.

 

Took coil pack out, there is 12v on the middle connector pin but i dont think im getting a spark. Although i have a worry that the spare spark plug i was testing it with wasnt seating right, do zeds have longer spark plug ends?

 

About to run ECU diagnostic to see what it flashes.

 

The main purpose of this post is: is there any way of checking my PTU (its series.1) is working without opening it up, or borrowing someone elses? Also is it worth checking the CAS with the above symptoms? PTU and CAS seem to be common causes of starting problems, no?

 

Another issue: since the Zed is a new purchase and i am about to do a full service on her, is it worth, in your opinion, changing all the coil packs?

 

Many thanks in advance!

Sounds the same as the problem I had,engine would just turn constantly and not fire,changed the Ptu and no problem since,that is untill this one fails, it appears from info I have been given on this forum that its not a case of if the PTU will fail, but when,I think a lot of members on here have gone for the series 2 Ptu that eradicates this problem,as far as I know you cannot test the PTU

That is as i suspected.

 

ECU code gave me 55 no errors and i dont see one listed for PTU.

 

Just going to find an assistant and re-check for spark.

 

anyone have a PTU for sale, id prefer the series 2 version?

No problem,hope you can sort it!!

Still on the lookuot to buy a S1 or S2 PTU or someone nearby to loan one to make sure its the problem. Thanks.

Can someone please link me to that page in the manual with the PTU continuity test? I have the PTU out now but running in circles trying to find the right page!!! maybe just me being an idiot and looking in the wrong place!

 

Thanks.

i live in gloucester have 2 zeds can borrow one from me if you want?? plus also have conzult etc

would be really great if you could mate, this problem is driving me up the wall! thanks a lot for the offer.

 

Im seriously hoping that its just the PTU so plugging a known good one in should help me out a lot.

 

I have tomorrow (monday) off if this helps, when is good for you, again thanks!
