FLIPPING HECK, CUPID STUNT... I don't need a sensor is the long-and short of it.. But it was "interesting"...
THE SENSOR IS OK!!! It's the (out of) fuelling!
I went out expecting to be taking the sensor off.... I wired in the scope to the sensor-output and initially I got the nice saw-wave I was expecting... Then there was the odd *spike*… I went to get the camera but then more and more spikes.... Then the engine cut out, !!! *AND* !!! the petrol pump went mad noise-wise when it was called to pump....
Maybe the 1/5th of a 5litre can that I put in last week has been used/is vapour...! No wonder it wouldn't rev, and constant bleeding of the injectors rail bubbles, probably was air out the tank... 4 foot snakes..
I've lost the most basic diagnostics skills when it comes to cars not driving for so long.. The carburetted Morris-Mini with-points will probably be my limit as an automotive engineer, it's a good job I don't do cars for a living! I'm a programmer, I can't help staying clean and knowing what I'm doing in reality!... :-P :-D (if you ever saw the winter-big-wheen in hyde park I did the lights!)
More my kind of project now I might look at when I get back from London:
I've been playing with PIC's a lot,
I can get a CanBus devkit to look at the ECU output, I bet MicroChip'll send me one if I put more videos of it on my tube-channel again.. I've got loads of kit like that!
I bet I could make one chip drive gauges/green/red-lights for everything important off the ECU and/or even have a little OLED display..
But it's gotta ask the question "is there petrol in the tank Neal?"
Cheers for the info, it's good to check first though init!!!!
Thanks! :-) NEAL
