marmite monster 0 Posted October 28, 2010 hum cold start injector is a good shout how do i check if that works? Quote Share this post Link to post Share on other sites
Wullie 1 Posted October 29, 2010 I found the easiest way to check the cold start injector was to unbolt it (2 Allen screws) when the car is cold and get someone to crank it over while pointing the invector into a glass jar. It should spray petrol in a cone into the jar while cranking. Stop cranking, wipe the injector dry and wait a couple of minutes too see if the injector leaks petrol. If it does basically it's foobarred but this would not be your current prob;em as leaking would not affect the cold running. More likely to result in lousy MPG. Two birds with one stone. Replace the valve, start the car and run it up to temp. (over 30 degrees C is the cut off figure I think) then quickly remove the injector again and try cranking the motor again. There should be no petrol ejected. Cold start system checked by undoing 2 screws twice. Not being electrically minded I find this easier to do than checking resistances and things with amps amd volts and multimeters. Quote Share this post Link to post Share on other sites

ben_wooduk 0 Posted October 29, 2010 Be interested to hear how you get on, mine doesn't sound as bad, but certainly runs a lot smoother when warm Quote Share this post Link to post Share on other sites
