I have a 99' stock 120k motor. It's been running flawlessly since I bought the car. Over the weekend, I changed the oil and replaced the motor mounts.
#1 I replaced the motor mounts by jacking the front of the engine using the crank pulley as my lift point. Did not disconnect the battery while doing this.
Engine turns over, but won't fire. Checked spark in one cylinder and no spark. Could I have crushed something on the way up, all help and suggestions appreciated.
#2 Unrelated, I replaced the starter with a new Mazdacomp starter a month ago because it would take many key hits(not hammer to starter) before turning over. Once it turned over it would fire immediately. I've checked for killswitch wiring problems, but nothing obvious.
Thanks for the help in advance.

You could have damaged the connectors to your coil pack near the firewall when you jacked up the engine. Check by taking a look and make sure they are connected properly.

Thanks Gale, I'll take a look tonight, I hope I didn't break anything and just disconnected as you suggested.

Check the timing wheel for damage and check the timing pick-up coil on the left side of the oil pump for damage or wire damage. Check the pick-up to timing wheel gap. It should just miss the teeth on the timing wheel when it lines up with the pick-up coil. FYI, I would not recommend the front pulley as a jacking point.

Coil pack wires are also a good check.

everything was fine after they got the fire put out.

The timing pick up coil had shifted up, so the wheel gap increased to over 2cms. Loosened, repositioned and started right away.
Thanks for the help, lesson learned. [Smile]
