No power to the distributor

[Roice]

I need some help with my class 9 car. I have power to the coil and from the coil to the distributor but nothing to the plugs. The coil and distributor are both good. Any ideas on what could be wrong? Thanks.

To much clearance between the points or the rotor and the top of the cap.

Thanks

I tried two complete different distributors one with points and one with electric internals and neither one work. I think the cam may be a tooth off.

Is the rotor turning when the motor is cranked?

Are you getting spark out of the coil wire will the motoe turns over?....because even if the cam timing or distributer timeing is off, there would still be spark.....If your problem is a "crank, but no start" then it could be timeing.

You need to crank over the motor and check the spark coming out of the coil wire....do that first...

A weak spark can seem the same as no spark. You swapped distributors, so assuming everything was connected properly that rules out the distributor. Maybe try a different coil? You mentioned a tooth being off - was anything relative to valve timing changed? Something like a cam swap? Usually if a timing chain or belt is off it'll still run, but it might seem lazy or it might backfire.

The rotor is turning and the coil has pleanty of spark. We have tried multiple coils and distributors. The engine does backfire horrible when we try to start it. That's why I think it may be a tooth off.

Sounds more like you are 180 deg off. What was the last thing you did to the eng before it started to act up?...if you did a timing chain/belt, then that might be it...You might need to go back to basics, get #1 up on about 6-8 degs BTDC and re-posistion the distributer...then set to actual timeing specs...

We got it fixed and ready to race in just a few short hours. Thanks everyone for the help.
