well i finaly finished puttin my rebuilt engine in last nyt! was running brill untill it cut out and now its missin on No.1 so i did a ecu check and it came bk with air flow meter and ignition system! so im thinkin that it could be my PTU. as its 15 years old! :(

 

any other idead plz would be much apriceated!

IIRC if your airflow meter was shot you wont be able to rev over 3k

 

could possibly be PTU try a good working one and see what happens

check coil packs are in tightly,and do a compression test once all up and running make sure readings are with in spec

I think it's more likely to be a bad connection to the ECU - check that big blue plug.

ive checked that and its ok! forgot 2 mention that its not revvin above 3k!

 

so the things are!

 

only runing on 2,3,4,5,6

wont rev above 3k and me vak is only 7mg.hm ( summat like that usin a nother boost guage )

 

last nyt it was running fine just slowed down to pull in me drive and put me clutch in and it died! started it agin and its missed ever since!

 

PLZ HELP! :headvswal

Have you tested the coilpack on Cylinder 1?

 

Check your getting a spark and also check the plug is OK....

 

Its gonna be a process of elimination......if all else fails, give jeff @ z-edworld a call...

I'm always suspicious when multiple things fail at once.

Also, when the AFM fails the engine won't rev above 2400rpm IIRC

yep tested that, and no spark.. checked the coil pack, (got 24 of the dam things ) thats readin the right impedance. (around 0.8 - 0.9 ohm) even checked the PTU. but it gives me some funny results! like no ground but it still works on all the other coil packs! i conna work this out! :wack:

and i forgot mention, that b4 i blew the bottom end last time! the put was playin up! and i gave it a tap and it went ok! finger does point to that! ( well i think so any how) is so would that make the ECU say that theres a ignition fault! ????

ive checked everythin now

 

ecu

CAS

plugs

PTU

coil pack!

injectors and its still not firin on No.1

its doin me head in, 1 min its fine the next it stalls out and now wont run propperly!

 

can any of you technical boffs out there shed any light plz! :headvswal

Sounds like you've got a major problem there mate.....

Lol well i dont actually know anything about zeds, so i cudnt help anyways...just sounds like turboslippers situation is quite bad, thats all!! Sorry for being thick! :rofl: ;)

fpmsl, :rofl: :rofl: at least it was showing concern!

 

go on stick up a post introducing yourself - you know you want to!

well ive taken the plennum off and im goin check if me head bolts are all tight! as ya supposed check them after its run for abit with new gaskets!! appart from that! i dunno! could be a valve not sittin right!

 

i realy dunno! think ill have give baggins or jeff a ring v soon!

 

its realy depressin! ya put all that hard work (and money) and sumthing sez NO, IM GOIN ME A PAIN IN THE FO*KIN ASS! AND GIVE YA LOADS OF GREEF!! :headvswal :headvswal :headvswal :headvswal :smash: :shock: :cry: :bow:

I really feel for you mate, im in the same situation my boyfriend has a z and it isnt working, so not fair!!!

Whoa mate, hold your horses a sec, heres some positive thoughts for you before you start stripping everything off again.

What gives you funny results mate? The coilpack or the PTU? The PTU can be held resposible for a multitude of sins, ie.strange responses when somethings not quite right. Try changing the PTU for a different (proved working on another car) one. For the sake of £70!. And then check the readings again?

 

You havent spoken about the condition of your loom? Would you put your hand on your heart and say the looms spot on? I know mine wasnt after 15 years service, it was fooked to say the least.

 

Also, try a donor ECU, are your injectors standard or upgraded? For the PTU and ECU you could drive to jeffs and he'd loan you one to rule them out the equation.....

 

I am betting its one of these at fault or the loom...what else is there?!?

PTU's can fail in two different ways. Either conpletely when the main earth breaks or on a single cylinder when a different wire breaks. Borrow one to see if that fixes it.

 

I have a spare Series II one and I'll be in Middlewich this weekend, which is only about 25 miles from you if you can't find one closer.

 

(I also have a spare AFM) - Two birds, one stone etc ....

And at the end of the day mate, its just a fooking bunch of wires connected to engine components.......the engine ECU and loom looks like a piece of piss out on the ground, trust me......give me a good length of wire and I could create one..... ;)

ive checked it with another PTU! also i re did all the loom b4 i put the engine bk in! ie, new coil pack plugs and injector plugs! ive tested for spar and thats fine! also checked the injector and that spittin ok!..

 

i rang baggins up and he sed that hes got a z in at the mo with the same prob and its the injector seal leakin! so im goin try that 2moz! if that fails god know! could be a valve or ring! but ive only just built it up! and it dont explain why 1 min its ok then the next its gone!

yep tested that, and no spark..

 

I'd first try to solve THAT, before doing any stripping of plenum/heads/injectors.

A leaky injector/seal won't cause that.

Also in this case there is a leak, the cylinder will be filled with petrol in no time (after letting the car stand for a few hours)

This is also a very bad for your engine, since fluids (like water/fue) won't compress as much as air and you can hydrolock your engine while trying to start it.

 

Also do a compression test and if results are bad for nr. 1, you may have found your problem.

 

>> check if me head bolts are all tight!

 

I doubt that's your problem....

But, you're supposed to do that before putting the engine back together.

the service manual specifically states to tighten the bolts to spec, loosen them all completely again and tighten them to spec for a second time.

A leaky injector/seal won't cause that.

 

My thoughts exactly.....

 

a knackered injector perhaps?? :confused:

found the prob and all fixed! (thanx 2 ry at ZTECH!) it was the locator peg on the VTC GEAR! it had snapped off and the came gear was spinning but the cam was not! (due to the bolt not bein tight enough! so i put a new pin in and away i want comperssion test was bob on for all the cylinders! but im gettina a splutter now and agin but its my ptu this time! if ya give it a tap it goes off and clears up after 2500rpm!!

 

just whan to say a big thanx to ry @ zteck. top bloke! ;)

bloody hell this could be whats wrong with mine,, mine is in at z tech at mo with exact same problem , have done all of above , fingers crossed, ryan can sort it ,.,

no thats not the problem with yours Paul, Turboslippers had no compression along one whole bank :( you only have one cylinder down
