2ltr petrol wouldn't start today. Early Mk1, with 110000 under its belt. Charged battery, just in case, and had a look on here. Fuel pump relay seemed ok, but following someone else's suggestion, floored the throttle and tried again. Hey presto, sprang into life, and seems to run ok now, at least on a quick spin around the block, no fluctuation at idle.
So, glad it's going again, but I just wish I knew what was wrong, in case it happens again. Could it have been some dirt in the fuel system somewhere? Or is the throttle controlled by some electrical widget that could play up. It should really start with no throttle input. Wierd. :shifty:

The only electrical intervention could be from traction control. But even at that the throttle is NEVER fully closed. So im not sure where teh problem could have been.

Did it fire up but didnt catch? Or did it not even sound as tho it was doing anything?

Caught briefly, then stopped, and wouldn't start from then on. Churned over, but not a peep, even leaving it for a while. Of course flooring the throttle used to be standard practice for a reluctant engine, but it just doesn't seem right with fuel injection.

could be a bad temp sensor. If it thinks its much warmer tahn it is then it wont add the extra fuel it needs when its so cold out. It could also be a million other things, but if you have a multimeter then it would be easy enough to check.

On a cold engine the air temp sensor and teh coolant temp sensor should have similar resistances
