All ignition coils are new. I've ruled those out. I just dropped the battery off at autozone for them to recharge. I'll pick it up in the morning. However, last night the battery was fine. In fact, I even hooked up my fathers car (via jumper cables) just in case that was the problem. But no luck :(

I'll investigate the camshaft sensor in the morning and let you guys know what happens. If that isn't the problem, I think I might just get the car towed.

I'm just so stumped as to how a change of spark plugs could cause this. The autozone guy thinks I might have accidentally disconnected something somewhere, but I've retraced my steps a million times now and everything looks fine.

Technically though, can a non-functional cam position sensor result in the symptoms that I've described (crank, but not start)?

What's the difference between a crankshaft and camshaft sensor? What I pulled out looks like this:

but the crankshaft looks similar

There is a cardinal rule in car repair: when a new problem develops after some work has been performed, go back and look at the area that you just worked on.
In 99.9% of the cases, you can find the problems to be "self-inflicted", i.e. caused by yourself while doing the repair.

cn90, I've gone back and looked over what I did more than a couple of times now. I know that's the rule, but I don't know what else I could have missed.

I brought the battery back and reinstalled it this morning. Then I disconnected the camshaft sensor from the switch end and tried to test it using my digital volt meter. The Ignition was on in the II position. I'm not getting values for anything. I tried reading it on the AC and DC volt settings and nothing at all. So I'm assuming the sensor is the problem. The part comes in tomorrow so hopefully when I install it the car will start! I'm keeping my fingers crossed!

I'm also getting two codes, p1113 and p0013, one of which is camshaft related. Hopefully this will be the solution.

I'm gonna cut and paste something I've written before, so it's a little repetitive, but gives you the values you need to look for from the sensors:

The crankshaft sensor is located just above the transmission housing; the camshaft position sensor is in a housing just behind the distributor cap on the engine block. You should see >200 ohms on the crankshaft position sensor, and often times the cam sensor will set a code. Pin 1 to 3 of the camshaft sensor should read 12.5 V, 1 to 2 should read <5 V, and pin 1 should ohm out 0 resistance to ground.
You may want to specify to the OP how to take these readings:

If the sensor is plugged in or disconnected.
If it is unplugged, which half of the connector to get readings from.
Whether the key keeds to be on.
And clarify meter settings between continuity (ohms) and DC volt readings.

Also, post a few pictures of your engine setup, post pics from cylinders 1 through 5, all the way to the wiring beyond the engine.
Perhaps someone here can capture what is wrong in the pics.

The cam sensor comes in tomorrow. Hopefully that's the fix! If not, I'll be back . . .

I installed the cam sensor, and it still cranks but doesn't start :(

Any ideas?
