audi 100cs quatro sedan: I put a new water pump in I marked

This answer was rated:

I put a new water pump in I marked all sprockets I believe timing is right will not start seems like no spark. Any ideas

I'd suggest doing a compression test on all cylinders as they should all be within 10-15 psi of each other as this will show if the base engine is healthy and if the cam timing is correct

While I was waiting I took it all apart and redid all my work. Runs fine now. This was a used car from a friend found out he had dealer change timing belt a couple of years ago. The light went on!! The car was running flat and poor fuel mileage I did a little research on the alldata site (looked close at pictures) and figured the dealer was not completely correct. Now the thing runs much better alot more power.Thanks for responding anyway.
