240Zdragon72

The engine will crank with the key, (now that I've installed an Optima "Red Cap" battery) I changed all the connectors to the starter. They where green.:stupid: Now the engine will turn over, but no spark. could there be a short to the coil, or should I try putting the old coil on? Brian:alien:

I have just aquired a '72 240Z with a 280Z L28 engine. Here is where it gets tricky.... new sparkplug wires, coil, and Optima battery. Still not cranking. It all started with me and my wife trying to jump the old battery. We got a quarter of a crank but that was it. Then the next step was to put the new battery in. NOW from the ignition, I don't even get a crank. I can hear the (I guess) starter relay clicking but nothing to the starter. Took the starter off, works as advertised. Put the starter back on, still nothing. Then back to the starter....I put the jumper cables on my other car and took the - and mounted it right to the - on the starter. Then taking the + side of the jumper cables and touching the + side of the starter, I'm getting the same quarter of a turn and no juice. On the instrument panel, all the bells and lights work. BUT NO JUICE??? If I took the sparkplugs out of the engine and try it the same way would it even matter? (maybe the chambers are full of gas?? Thats the last troubleshoot opinion I got...) think it will work? Thanks for reading my problem......Brian
