Hello everybody!
Long time no see, my old petrol 450 600cc Mk2 -2000 have been standing long time now for other reasons than the car it self.
As some might remember, this engine is modified with higher compression for take the full advantage of ethanol, E85.
It was running beautiful except that I had problems with oil consumption and blue smoke.
Some year ago, I finally think I have found the reason, the sensitive crankcase ventilation needs care and a blue silicon TIC hose that I added before the turbo (to get rid of the stupid restriction there) seems to be a big part of the problem. I made some tests with a prototype oil collector on the crankcase ventilation system and the smoke went away.
Good, then I only will change to fresh spark-plugs and I can start to use the car agan! (This was some year ago...)
I have now replaced all 6 spark-plugs and now I wanted to start up. (Alternator is not stuck and I can turn the engine by my hand on the v-belt)
It fired up a bit some 1/4 of a second but after that it only cranks when I turn key and makes some irregular ignitions.
I managed to get in some gasoline (!) in the inlet manifold via one of the crank case ventilation connections and a temporary short hose and then there is more ignitions. One time I forgot to put a plug in the hose so there were going extra air around the e-throttle, and then the engine actually started to ignite evenly, but weak for some seconds when I cranked in the same time.
There is ignition according to an induction timing strobe that I have connected, but seems not to be on all 3, all the time. (Seems to be most present spark on cyl 3)
Seems that ECU is shutting off one or several cylinders after some tryings.
Fuel pump is running as usual and fuel is coming when I disconnect the pressure hose from fuel rail connector.
Any ideas of what it best way of further fault tracing here?
What is the best way of checking if the e-throttle is correctly behaving during start?
Grateful for any input!
