Ok did it run before you got a new cap. If it did then take off the cap and lick it. No just kidding. Take it off and make sure you got the littl springy thing in to its seat. I had mine off the seat one time and was t wondeing why it was so hard to get on. Put it straight on. Don't force it.

No it didn't run when I replaced the dist. cap. When I put the new one on it slid on perfectly wasn't harder wasn't easier than taking the old one off.

Problem solved the timing belt skipped a tooth I had to retard the timing all the way back just to get it to run.

So if your car gets spark gets gas and doesn't start check the timing.
