Hi,
I've got a problem with my 2nd car (rover metro, carburettor model). I was driving it from my house 2 weeks ago, and had got 500m down the road when the engine revs just died smoothly (no coughing or anything like that), until it stalled. It was as if the accelerator did nothing at all any more. She hasn't started since. The engine cranks fine, but just doesn't catch.
I've done some diagnostics, and here's what I've come up with:
1) spark seems to be good. I took one of the plugs out, and could see the spark jump across to the block when I cranked it. I've also used LED in-line lead testers, and they light up as expected.
2) The air filter looks in good nick, but I've taken it off anyway (the carburettor is below it, which is one of my main points of focus).
3) I tested the fuel pump outlet with a vacuum/pressure gauge. That registers fine.
4) I checked the damping chamber on the carb. It was a bit low of oil, so I topped it up anyway. Car still doesn't start
5) The fuel gauge is over 1/4 full (i.e. not down to the dregs), and the mileage I've done would confirm this. Should be another 50-100 miles at least in the tank. I've shaken the car to try and hear petrol sloshing in the tank: couldn't hear it, but that may be due to my cloth-ears! I've also tested the outlet of the fuel pump by disconnecting it. Petrol spurted out when it was cranked, so I don't suspect a "no petrol" problem.
6) I've had a look at the spark plugs: even after 5 seconds of cranking, only one of them was wet (and it smelt like petrol). The others were bone dry.
Any advice that anyone has got would be gratefully received. In particular, what would suddenly cause only one cylinder to get supplied with petrol, whilst the car is running?
in advance!
