A long shot but am hoping.

Is there anyone on here thats a bit of a whizz when it comes to sorting the electrics out on the z32?.

I am at,a standstill and am without a car so really need mine on road asap but am having problems with the electrics and car wont even try to start.

So if someone could spare some time to help i would be very grateful.

Thankyou.

None?

I'm not local, but if you can be a bit more specific it may help.

 

Is the car attempting to turn over?

Is the MIL light on the dash?

Have you checked for any codes on the ECU?

Got code 21 on ecu test. Cars trying to start, injectors are firing, and have changed ptu. Still wont fire up.

Did you change it for a S1 PTU? still sounds like the PTU to me, are you getting a spark at the plugs? have you tested them one after the other

 

I changed my PTU once, and it just kept cranking the engine with no fire, changed it back to what i thought was my fooked PTU, and it fired but then i had a misfire when driving that would make popping, so redid the clips and bingo, nice sound driving.

 

Next logical step would be the crank angle sensor, then the coil packs, then the spark plugs.

spark plugs are sparking, ptu was off a series 1(working).

are you getting a strong smell of fuel when cranking but no fire?

 

get a photo of your engine bay up. might be able to see something that you have missed.

 

If its cranking, but not firing, then its either the sparks or the fuel getting to the cylinders thats the issue.

 

check the fuse in the small fuse box 30a for the fuel pump, when you first turn the key do you here the fuel pump engage, before you crank the engine?

Cas is working, checked that today. Coilpacks are making spark plugs spark. Im really at a loss at moment.

just read your other thread, was your car ever a auto? if so id get that reverse sensor plug sorted out, if it still has the auto ecu in it, may be its thinking the car is in reverse so refusing to let it start.

 

but code 21 is defiantly PTU related, ill get my PTU off the car tomorrow and send it to you, its known working good one, and will give me the kick up the butt i need to get my S2 PTU on it lol

Thankyou ian that would be very helpfull.

The small fuse box at rear of bay has had all the fuses checked and are fine.

mike bean thibks i should try another ecu.

the car has always been a uk manual.

The fuel pump is priming, so i assume that would mean it is working properly.

 

Thankyou everyone for the replies. keep them coming as i will be trying all suggestions i havnt tried upto now.

PM me your Addy bud, ill get it in the post first thing, should arrive with you once the post picks back up after Christmas day, need to get down the post office as i have a center arm rest to send out.

When I was there the car had fuel pressure but the injectors where putting no fuel in. I think everyone should know the car has been stood for about 4 years so anything is possible. All injector connectors where so green it was untrue. I havw cleaned them aS good as I can. I think its worth trying every majour electrical part but if no joy I think it will be water has got into the electrics somewhere. I really hope we find it as I know how much dave wants rhis back on the road.

 

Well first need to get rid of that code 21 which is PTU, im sure i have a set of 5 injectors, came off my red zed and were working fine before removal (one will need replacing as the protective cap over the injector firer has chipped) but a good base to start from, just checked and yes still have them, they are stock injectors off a manual TT
