4k Wont Fire

[Roo]

Don't be a wuss. Hang onto the end of the spark plug lead while someone else cranks the car over.

 

:hmm:

lol i done this is fun as.... can really tell if its sparking or not

Are 3k, and 4k fuel pumps different, the 3k has a shorter arm, and the 4k has a longer arm?

Could be it's not making contact with the cam maybe and not getting fuel?

Or like old fella said the white ballast resistor, mine wouldn't start, fire, and I removed it and started first time.

Good idea in theory, BUT:

 

The ballast resistor only powers the coil when the key returns to the "on" position.

Nickyboy can't get his engine to fire, let alone start so the ballast resistor would never be powering the coil!!!

 

On the other hand, check the other wire to the + side of the coil. You might not have 12v "start" power!

I assume you've already checked you do have power to the points, via a screwdriver over the open points with the key on- it should spark across the points, or a voltmeter.

 

Then if you haven't checked it already, tell us if there is spark at the plugs.

 

If you have spark at the plugs then that only leaves timing really, which you can check with a timiing light, or by watching the open dizzy with the key on while you turn the motor with a spanner. The coil should spark with an audible 'crack' and the points spark as they fire, and you can check that the crank is at the right number of degrees before TDC.

 

It wouldn't be the first time I'd put the leads in the wrong way, or assumed the dizzy went clockwise when it actually went backwards!

 

If you have that all sorted then fuel would be next...
