sc wont start
 

hello ladies and gents,

I am a complete novice at mechanical stuff, my 81 sc will not run. i know it has a spark and I know it has fuel getting to the cylinders but it just will not go. What do i need to check?

When's the last time it ran? How well? Did it just stop, or did it not start after some work? Where are you?

sorry, it was off road for a while getting sprayed after some little B***ard scratched it, wouldnt start at paint shop.ran like a bag of spanners about a month ago, ran for a bout 2 seconds yesterday (like a big bag of spanners) now doesnt even sound like it will start, this all began about a year agoafter the cdi gave up the ghost. so I fitted an msd, whilst this was being done had ssi's fitted, hasnt really run properly since, now i keep getting jolts from the plug wires, tried a new set no difference, new rotor new cap, same but plugs out and connected, all firing with a bright white /blue spark, that much petrol going thru it was at one point leaking from the ssis ! oops! Am stuck now.

Oh am in Dorset uk.

Gordon,

Sounds like it was running rough ... when running. May have had an airbox explosion/backfire??? Did/do you have an airbox pressure relief valve [flapper] fitted?

If the airbox has cracks in from a backfire or explosion ... it would have the symptoms you describe.

yep it has a pop off, could this be vacuum leaks? thing is now it just wont fire at all. has a spark has fuel wont do anything !
