I have a little Uno inherited from my dad. Just before he passed away he was having trouble getting it to start, and before that, having it die on a drive somewhere, even close.
I would now like to solve the non-starting problem first. The battery is charged and seems strong. It takes many tries to start and revs of the starter motor before it shows much discharge. I will be working alone, and therefore have difficulty with things like turning the starter and checking for spark. I will rig a jumper lead from the battery to the starter solenoid for this.
I see the possible causes of non-starting as:
- no spark voltage from the coil.
- no voltage to individual plugs from the distributer, very likely points.
- no power at all for the ignition system. No idea where to look here.
- No fuel. The car does have fuel though, ruling that out.
- No fuel reaching the fuel pump, i.e. a blocked line or filter.
- No fuel reaching the carb, i.e. a malfunctioning fuel pump.
- A blocked jet or cannel somewhere.
- A stuck float or malfunctioning float valve (dunno what it's really called).
- A stuck butterfly, allowing no air and ergo no vapourization of fuel.
I'm asking this question not to directly ask what is wrong, or what must I do, but I would like to narrow things down, and am hoping that members here familiar with the Uno could give me a start, say a prioritization of the possible faults I list, and, or, additional faults I could check.
