please help sos!!!!!!!!!!gotta drive 3 hours tommorow and just sold my other car need it goin thanks

check for fault codes on the computer

nothing involved in the conversion effects the engine management

have you tried swapping it with another relay?

and check cas sensor aswell

[Skids_mate]

will the cas being dirty stop the fuel pump goin or throw the injecters out of wak

[HARVZ-6]

wont effect fuel pump, will effect injector pulse, its timing is controlled by the cas

[GetToDaChopa]

Could it be a low battery voltage?

[HARVZ-6]

if that was the case it wouldnt turn over..

[Skids_mate]

turns over fine just wen u stick a circuit tester in the injecter plug it comes up as both little female prongs inside the plug both being positives instead of one positive one negative but one injecter plug is correct the rest are wak

[HARVZ-6]

the all fire together it ones fine and the rest arent, its a wiring problem

[Skids_mate]

where should i start

[HARVZ-6]

id check the computer for faults first,

if nothing comes up id check cas sensor

[Skids_mate]

ok cheers mate

both injectors will be possitive but when the dissy spins and activates the pulse the system uses the reverse polarity relay to convert one power too a -12v and allows the pulse for the duration

try swapping the metal relay down in your guard near your battery but makes sure its the same type,


the dissy also does run the fuel pump

possibly bad earth under relay plug. pull it out and check wires crimped onto spade connectors.
Generally clicking relay means either 2 things
Bad earth or stuffed relay
or both
:P
