Engine will turn over but car wont start. Help please!

Yesterday morning i was driving back home from a city about 100 mile south of where i live. About halfway home, my "service engine soon" light comes on. Of course it could mean hundreds of different possibilities, so i didn't sweat about it and just made the drive home.

When i got back, i proceeded to do a few on/off starts to see if the service engine light was just something phony like a misfire that the ecu picked up. Nope, Still on. I also came to notice a rough idle develop after the few times i turned the car on and off.

So now i go to unplug the battery and let it sit over night to see if this will do anything (i.e. get rid of the service engine light), and here is where it gets ugly.

This morning i put the battery wires back on the terminals and go to fire her up, and now she wont start. The thing is that when i turn the key to position 1 and 2, everything works; the radio, AC, etc. But when i go to start the car, it won't fire up. The engine turns over and attempts to start, but nothing.

What might this most likely be? A bad fuel pump? Bad fuel lines. Ignition?
Any advice or feedback helps and is greatly appreciated.

A fuel pump should have left you stranded. Get the codes read.... Too many possibilities.

What kind of Diagnostic tool do you recommend using for reading the codes? I've heard of one called a Peake tool that seems pretty popular. I ask only because i know nothing about vehicle diagnostics. thanks

I have the peake research diagnostic tools. It pretty easy to use. It is about $149. I have never took my car to the dealer for the last 3 years. I pretty much diagnose my own car and replace parts when needed.

Not true, I had a bad fuel pump in my E36. It would work sometimes, then eventually quit working all together. Without turning the key all the way to crank the engine, try turning it to the position just before ignition and see if you can hear a faint whine from the back (the fuel pump). If not, maybe dead fuel pump.

I'm really glad u brought this up as i'm beginning to think more and more that the problem may be the fuel pump. I forgot to mention that when i was driving back home, my gas mileage suddenly went all out of whack. I was averaging 12 mpg for the last 20 minutes of driving. This combined with the fact that the engine turns over and gets a spark makes think it must be.

Would you say that it's worth the money and you get what you pay for?

Well I just bit the bullet and bought a Peake fault code reader.

My fuel pump wnet bad twice, not sure why. It is an easy repair and some good DIY on here. Look at your #54 fuse.

Would this be in the black fuse box under the hood?

If the fuel pump is working, you should hear a buzzing or hissing noise from near the rear driver's wheel well. The fuel pump will start to run as soon as you put the key into position 2. So, open the door, put in the key, turn to position 2 but don't crank - you should hear the fuel pump run for 10-15 seconds, then stop.

If you don't hear the fuel pump, your first things to check are the fuse #54. If it is good, swap the fuel pump relay with the horn relay - they're the same part number. If you STILL get no fuel pump noise, check voltage at the fuel pump wiring harness - pull out the rear seat bench and there's an access panel where you can get to the fuel pump. If you have voltage at the fuel pump, but it still doesn't run, then you need a new fuel pump.

If you CAN hear the fuel pump, then I'd suspect camshaft position sensors, as mentioned above. You'll need a scan tool such as the Peake to diagnose further.

Does the camshaft position sensor throw a code?

Thats is correct. I replaced mine since my car stalled more than 2x and feels like it was coughing like it is gonna quit. Used the Peake Research and it gave me the camshaft position sensor code. Ordered it from Crownauto for $93 shipped, takes about 1 hour job since I was very slow and now it ran likw a champ. no more engine stalling.

Do you happen to recall the fault code?
