When trying to start my cossie engined capri the plugs get damp after a few revolutions.if i take the plugs out and clean them,it trys to start but then they get damp again.Have fitted a new coolant temp sender(the blue sensor),still same,any ideas?

 

check the map sensor also!


may need abit more info on the symptoms ie when it last ran etc what have you changed

 

has the car run with the spec/mods you are currently at? ie has it stopped working or has it not worked since you changed something?

over fuelling, could be the wrong chip/injecotr combination, faulty map sensor, too high fuel pressure, (kinked or bent fuel return lines to teh tank)

 

I had it running previously but then it started over fueling for no apparent reason, the plugs were getting damp.Run fine in the sierra,so i changed the coolant temp sensor,it hasnt run since then, the plugs get wet after a few turns of the engine.
The coolant sensor is new and iv checked the resistance as per workshop manual all in spec.The car runs the standard chip at the moment,iv had it running with this one before.
All the fuel lines are new and look ok.
I noticed that the fuel pressure regulator has been messed with,and the screw is in quite far,could this cause it?
Thanks for the help.

 

if the fuel pressure has been ajusted, yes, are the injecotrs either the dark blue or yellow ones if its a std chip, and also is it a 2 bar map sensor, part number APS02/03 ?

 

Its running 2wd standard yellow injectors,standard chip and a 2 bar map sensor. The screw on the regulator looks like its been turned in as far as it will go and the factory fitted tamper proof plug as gone, so some monkeys been messing..It came off a chipped car,i looked in the workshop manual and theres nothing about adjusting it

 

is it a factory fuel reg, or a FSE ajustable one?

get the fuel pressure checked fist job i reckon

 

agreed!

and then go for the map sensor if the pressure is ok!

 

Ok, cheers guys.standard webber pressure regulator.Got a spare map sensor will try that on aswell.

 

how did u get on?

 

Turned the screw back all the way,which resulted in the plugs not getting as damp,so im on the right track i hope! iv been told it could be knackered, so going to have another play with it see how it goes,been stuck for time recently to look at it. It did try to start though,but ther battery went flat! Will let you know what the outcome is.
