2000 Chrysler Cirrus Question: What does "No Bus" mean, and how do I fix it?

While leaving a parking lot yesterday, my car just stopped; this has never happened before. Yes, I filled up a few days ago. I checked the gas cap, and it was completely loose so I tightened it. I started to drive over a speed bump and before I could get over it, my car cut off. On the dash were the words "no bus". It cranks but won't start. I've been reading and searching all morning and haven't really found anything useful; there are a couple of checks I will perform in the daylight, such as checking all the fuses, see if radio/headlights work and attempting to disconnect battery. Is this something that I could possibly fix or won't cost major $$$? Thanks in advance!

    well, you need spark, fuel and compression to run. you need to start there to see if you have any of these functions.

    the no bus message is a communication failure with the computer. you have about 6-8 computers that all communicate with each other and when one fails then you have this message. it needs to be diaged from a shop to determine which computer has failed and why.

    if it is one of these, it could get expensive. after spending the money for a real diag, you will know for sure.
