She is running, turned out to be the fuel pump was not running and nothing to do with the tappets or a flooded engine!
It threw me as the fuel pump never used to run on the ignition switch anyway, but obviously ran when the engine was running (engine/exhaust too noisy to hear it!).
I connected the pump directly to the battery and she started and ran like a dream!
I have a question, anyone know how the pump is connected normally?
As I say it's not connected to an ignition feed as it didn't used to run with the ignition on; only when the engine itself was running and I presume during cranking. I can't find a feed which is only live when the engine is running and not live with just the ignition on. I've checked all the fuses and they are fine, although none are specifically marked as fuel pump.
The car looks reasonably well wired (although it's a Rover V8 into a TR7 so could be anything!) how would you guys wire it in?
I am tempted to wire it to ignition but there isn't a return feed for fuel back to the tank, at least not from the carbs themselves (twin SU's) you can hear the pump struggle when the pressure builds up if I don't start it. Can you flood SU's like this?
At the moment I have installed a single wire from the battery to the pump to get me to the MOT on Saturday. I assume it will fail on that? If that's the only thing I will be a happy man!
Keep well all,
Will
