SOURCE: Timing Belt Problem-6 cylinder Saturn wont' start

If your timing belt broke, then it is possible that the valves in your engine got bent, which won't allow the cylinders to pressurize the fuel/air mixture, and it will let all of the mix to flow freely into the intake/exhaust manifold. This can be checked with a pressure tester that is threaded into the spark plug opening. A mechanic should have one, or you can probably find one at an auto parts store.

Just changed the water pump on a 2005 dodge neon and now it wont start. What could it be


You're not giving much to go on. Is it a 2.0L or a 2.4L?
You say it won't start. Does it turn over and not fire, or does it just sit there and do nothing when you turn the key?

Both engines require you to remove the timing belt in order to change the water pump. The 2.0L is definitely an interference engine, and I'm not sure about the 2.4L. But if the timing belt was not re-installed properly, it will result in a no-start condition since the valves will not be in sync with the pistons and spark. Best case scenario you correct the issue and are good to go. Worst case scenario is that if the belt is out too far, you bent valves and have to service the head(s).

I'm attempting to do a timing belt change on my 2004 Chevy Aveo. The problem is when I took off the old timing belt I forgot to loosen the tension using the water pump. When I tried to install the new...


Yes,there is a special wrench that fits the water pump. You have to loosen bolts on pump and put wrench on pump and turn pump to get belt on. Then tighten pump till marks line up on tensioner,then tighten the pump back down. Be sure to roll the engine around twice and recheck timing marks on crank and cams.

I have a 1999 plymouth breeze and replaced water pump and timing belt due to pump locked up and all the teeth gone off belt now. 2.0 SOHC that after setting belt and timing correctly the car wont start...


In general, backfiring indicates the cam, crank and ignition are out of time or out of phase. The timing marks on the crank and cam just line up the timing of the cam and crank. The alignment of the spark with them has to be phased at the right time too. Check the manual for how to set the distributor timing after an engine repair

Backfire, from tail pipe, every 2 seconds


sounds like the timing belt has jumped a tooth or two and is causing pre- ignition in the combustion chamber of the cylinder head. Have timing belt alignment marks checked.

no...water pumps do not cause backfires. faulty water pumps causes overheating.

backfiring is caused by incorrect firing order. the connection of your high tension wires are wrong
