Newbie bought 67 250S, will not start...
 

I just bought a 1967 250S from a widow. The husband had just bought it and it ran at the time. I know that he changed the fuel pump and it appears that he changed the plugs and wires. When I turn the key the engine just cranks. I checked that the fuel pump was working and gas is flowing. I also have sprayed starter fluid into the carbs and nothing happens. I found what I think may be the old plug wires in the trunk. I took some of the plugs off and put them back on just to make sure they are on ok. Every now and then the engine actually want to turn over, but thats about it. How can I check to make sure that their is spark for the engine to turn over?

Thanks for any help with this.

The engine now spits once or twice during a 5 second crank. There was a puff of smoke that would come from the Carb. when it spits.

250s
 

Check the rotor inside the distributor and the dist cap for cracks, carbon build up etc. if everything checks OK, check for power at the coil with the switch on, got power, Pull the coil wire from the distributor and hold it about 1/2" from the hole and have somebody turn the engine over, do not touch the end of the wire, no spark = bad coil, got spark, pull a plug wire at the distributor, "not the sparkplug " hold it 1/2" from the hole and turn the engine over, not spark= bad rotor or condenser.
hope this helps.

If you already know that the plug wires were changed, do you know that they were put back in the correct firing order? Good luck

Yes, remove dist cap, locate little line on dist edge. That should be #1 if no one screwed with it. The riring order is cast into the valve cover. It should say ZUNDFOLGE 1-5-3-6-2-4 The dist rotates CW.

I would also pull the plugs. I suspect fuel fouling. If they are fuel wet, the car willnever start.
