Hi guys the car has been garaged for a long time and won't start. At first I thought fuel pressure but that's fine. Getting a spark but plugs are dry so took the plug off the cold start and I'm only getting 9.5 volts and know I need 12 volts any advice on what to check next is appreciated

 

Did you try starting with out the cold start plugged in - iirc its the beige/yellow plug back on inlet?

 

Hi , i have a similar problem with my xr3 but mines only fires up on the csv , no compression no to sure where to go as well.
Is there any noises or power when starting it? u checked or replaced the bat?
Have u made sure the injectors are working , take them out but keep them connected to fuel lines put them in bottles and turn the car over they should spray out nice - or you could carefully undo the clips on the fuel distributor ( metering head ) , take the air filter out , turn the car over and slowly lift the plunger under it at the same time might need a mate to help.

 

Tried unplugging and still the same

 

the battery is new I've got fuel pressure and when I turn the car over and press the flap under the airfilter/ metering head it still don't start and get a strong smell of petrol, I tried it today with easy start spray in the intake and again nothing???

 

Usual checks then - fresh fuel? injectors pulsing?

 

Put 10 litres in but not getting any petrol to the injectors until I press the flap down on the metering head. Spoke to a guy in the local garage and he said it won't start until I get 12volts to the cold start

 

is 9.5 volts reading from battery? yes u need 12 minimum - start with a new battery sorry i didnt read the post properly .:0

 

the 12 is fed from blue black wire on ignition > there will be an intersection where wires are added at the point it turns to black yellow,..
it also goes to pin 24 jetronic black box ,
from that intersection it also feeds the thermo time switch, guess thats techincal name for a sensor ,
so check 12v is flowing through blue black, at ignition , on stage 2

 

Did you get your 12 volts to the csv?

 

No mate not yet I've not had time I've got 7.9 to the black box on the metering head and 7.5 to cold start , I will have another go tomorrow afternoon

 

Mate im no pro but im sure it should start up without the csv. Did you take that off seperate as well and spray the injector into a bottle?

 

No mate that's my next job, I seen somewhere that the cold start voltage can be anywhere between 9-12 volts? I did notice some petrol sat in the throttle body so think it might be working.
