'95 Discovery-- takes 3-5 seconds cranking or longer to start
When full warm and just shut down, takes 3-5 seconds cranking to fire. Other times, lots of cranking. New dizzy, coil, fuel filter. Fuel pump holds 27-29# when running, takes 2 hrs for it to drop some. No fuel in vacuum line to fuel pressure regulator. Not throwing any codes on Diag Display (it appears to work-- disconnected ECU got 02 code). The '95 does not have a CPS-- but is there another way it detects cranking speed and allows starting if/when speed is attained? Other than that, timing good and it runs excellent now-- just anxiety starting cold and/or warm. Sometimes I push accel all the way down prior to cranking-- that may help?
Probably not super helpful as I have a 98... but sometimes when mine is hard to start. I press the throttle pedal down all the way and let it go a few times. Turn the key and it starts right up. I figure it resets the max values for the throttle position sensor.
Put in a high grade battery ("borrowed" from my main project, putting 5 cyl Mercedes diesel in my 1951 ****** wagon.) Made all the difference in the world! Fires up 2-3 seconds when warm. Will see about when cold tomorrow a.m. I will also experiment w/ the throttle-- since fuel is not going to flood the engine, it might reset the throttle etc. Good thought. I hope that my stumbling along learning will help another-- we pay it forward w/ our efforts. Thanks!
