[andybond]

Dizzy or Dizzyless ?

 

[kev]

phase 1 dizzy

 

[Andyquadra]

dizzy cap, coil, timing sensor, ecu................just how wet did it get, or have you knocked anything off when changing the turbo?

 

[kev]

well it ran fine when I pulled it on the drive to change turbo it did get quite wet under the bonnet ive looked to see if ive knocked anything off but carnt see no obvious very strange im quite baffled by it

Check the wires to the coil pack at the back of the engine bay, pull them off and give them a clean and WD40 them.
Check the coolant temp sensor is plugged in
There's nothing on the turbo side of the engine bay that will stop it running, so either the water has fecked something up, or did you mess with anything on the inlet side? Unplug any fuel lines or anything like that?

I changed the injectors last week thats all but was ok after... the temp sensor plug did come off but I think ive put it back ok will that cause it not to spark if the temp sensor aint in right ?

No, that only affects fuel mix. Usually affects hot start to be honest, not cold start and defo not spark.

Check your TDC sensor is plugged in properly, and do you have a spare coil pack unit to try out? Have you spark tested at the king lead or spark plug? Try both.

Is there a turbo pressure safety switch on the turbo hose that may be disconnects the ignition?

 

[kev]

Right I've checked spark at plugs nothing and spark at King lead still nothing I've not got a spare coil pack to try the tdc seems to be plugged in ok I've also checked to see if there is live going to the coil pack from the plugs that go into it yellow wire and seems like there is live feed to it

 

[Andyquadra]

it hasn't got an immobilizer has it?

There is one under the black cover behind the battery, but it's not been disturbed apparently.

Can you smell fuel Kev? Is it firing the injectors?

 

[kev]

the alarm on it is old and abit faulty but not 100% if theres an imobalizer in it I don't think there is anyway and the fuel pump kicks in and I can smell fuel yes

 

[kev]

dave have you got a coil pack I could try mate ?

immobilizers sometimes cut the starter motor or the fuel pump or the spark, just a thought

I don't mate, mine is a later PH3 and I chucked everything else away that wasn't relevant to it sorry!

 

[kev]

still carnt get the thing going I tried a 5 gt coil pack to see if that would work ?? but still no spark
anything else It could be ???

 

[Craig Righton]

Have you changed the TDC sensor? The one that bolts to the gearbox.

Had on die before and it gave the symptoms you describe.

 

[kev]

no ive not tried the tdc are they still available ? ive checked the coil pack with multimeter to see if there is current and at the plugs that go to it and sems there is when ignition is on so all I can think of is distributor or like you say tdc

are the 5 turbo tdc the same as 21 as I have a couple of them laying around ?

Hi Kev,

Need more details for finding solution !

Probably a bad connection ?
