If its back firing you may have put the plugs back on in the wrong order, the firing order should be printed on your manifold xheck them and see if it does the trick.

When setting the timing marks together distributor always points to #6 not #1 put new timing chain & gears in but cant get it timed right 5.2


Is it possible to turn the distributor shaft 180 degrees and reinstall the dist ?
I am assuming you have spark at the plugs, just not at the right time ?
If the distributor has not been moved, and the rotor points to the wrong wire, you could have put the cam gear in upside down ?

1/ Have you fitted the spark plug leads in the proper firing order.
2/ Look inside the top of distributor Top (this is not the first time a new distributer cap has very small crack) or the rotor arm is fitting the cap properly. Hope this helps Best Wishes, Malcolm Campbell.

Replace the spark plugs and wires along with a distributor cap and rotor. Be careful to leave the old wires and plug wires connected to dist.cap, just remove dist. cap from the distributor and lay aside with plug wires on it then install rotor then new cap and proceed to replace each wire for cap and spark plug one at a time so you don't mix up the spark plug wire firing order. Cap laying to the side is used for reference purpose.

No juice to the distributor


I would go back and get it on TDC and see where your rotor is. Make sure you have it in time. Then you can run a hot wire from the fuse box to the distributor that would be hot only with key in on position. That should get you running, after that if you wanted to trouble shoot your old wire or just leave it with new, and tape up old wire just in case.
