1999 Plymouth Breeze 2.0 SOHC I just replaced the timing belt because the old one had not broke but rather had eaten off all the teeth so the timing was off. I set the timing mark on the crank to TDC and the timing mark on the cam to TDC but when I turn it over it sounds like it wants to start but just backfires a bit. Do you think that the crank timing should be TDC and the Cam timing BDC or does one advance it or what? Could you please help...

When changing the timing belt you need to place the cam shaft a TDC( clock wise), then rotate the crankshaft to TDC (clockwise), then back off the crankshaft (counter clockwise) THREE TEETH then back (clockwise) 1/2 tooth before TDC place your timing belt arround the crankshaft- water pump- and camshaft finally putting arround the tensioner pulley, holding 25 flbs of torque on the tensioner pulley to get the correct tension then push up on the hydrolic tensioner and tighten and you should have it.... rotate the crankshaft twice, if the camshaft pulley ends back on TDC then you have it correct.

Im having the exact same issue if anyone has a solution.

Just tried that... still no start...

You better get the specs correct or you can have major problems if this is an invasive motor. You can smoke an invasive type motor if you are not careful. Be sure before proceeding. Good Luck
