Hi all, got a problem with my ignition. Done a spark plug test by fitting an old plug to one of the ht leads and resting it on the cam cover. When I turn the engine over I get a real weak flash once or twice and thats about it. Firstly is the cam cover a good enough ground for this test, and if so what could be causing the weak spark? I've recently changed the crank sensor, phase sensor, distributor cap, rotor arm and ignition module, but same problem still exists. Any advice much appreciated.

 

the rocker cover has paint on it try putting it on the cylinder head and than try it. it could be the coil or dizzy, i normaly try it with a screw driver pushed in to the lead and hover it by were the plugs go in
