Have you checked the fuses and relays? How is the battery?

Default RE: no spark or fuel

This happened with my car too but it was my fault....

It took me a while to find but my problem was because I modded a 95 Alternator on my 98s harness because my 98 alternator froze up and all i had was a 95 alternatorand withthe extra wirelength it hung on theaxels and wore a hole through thewire jacket and electrical tape I had protecting the splice and grounded out on the axels and I would always blow my 20amp fuse under the hood. I was so baffled the day it stalled out on me at the stop lights because I took half of the motor apart on the side of the road tryin to figure out what it could be, I even did a spark test and purged the fuel rail which had no pressure then I thought the fuel pump and coil blew and here it was just my modded alternator harness draging on the axles... of courseI found this out after I got towed home by a Chevy!

I fixed it by taping it back up and shrink wrapping it and then zip tieing it against my overflow container. Such a simple problem became a call to my brother and a tow job from a Chevy and lots of **** for owning a Plymouth from friends.... []

I wouldn't worry I think this problem is pretty much specific to me...lol unless you modded your alternator or wiring.

Thing is fuses usuallyjust don't blow by themselves chances are even if you replace a possible fried fuse it will happen again till you find the main problem.

Both of those would do that as well.

so the camshaft and crankshaft sensor would not allow the fuel pump to kick on as well as the ignition not working. the fuel rail doesnt get any fuel. what would cause both the ignition and fuel problems.

Asd relay, or automatic shut down relay, it will kill the 12 volt feed to the injectors and coilpack. Start by removing the coil plug, place a test light on the connector for the green/orange wire and the other end of the test light on the negative battery terminal. Then have someone turn the key to the on position and see if the test light lights up.

You are positive that the fuel pump fuse is good? The Pcm draws power from the fuel pump fuses (as does the fuel pump, who would have guessed) so if that is blown, nothing will work.
