BlushGetting pretty frustrated with this *%$# car. It is getting feul and spark but doesn't even seem to try firing. As far as I can tell the timing is dead on and the ignition module under the coils as well as the crank sensor are new and working good... The plugs were good and wet when I pulled them to check... The firing order is good and all wires are in their correct places... HELP PLEASE!!! I need some fresh Ideas...Pirate

You need to check 2 things. First make sure you have a strong spark by testing it with a spark tester and make sure the spark can jump a 1/2" gap at the plug end of the wire. If that checks out OK, do a compression test on all 4 cylinders and post the results..

Ok... Cylinders are within 4 psi of each other and at an average 92 pounds. Ran out of time to check the spark gap idea... gas is good with no H2O and even tried a couple bumps of starting fluid but still didn't even try to fire...

You have a serious compression problem. That is no where near enough compression.
