My 2001 2 door civic 1.7 engine was due for a timing belt so I had a mechanic install it two days ago. The car ran fine up until today. My check engine light came on and my tach stopped working and the car is sputtering and stalling and the green security light is flashing. There seems to be good spark and gas. The car is burning really rich as well. I tried to retrieve the codes with my code reader but it keeps coming up that there is a break in the data link. My code reader works on my crv so I know that there is nothing wrong with the reader.

Hmm...if the problem started shortly after your mechanic worked on it, the only suggestion I have is to not touch anything and take it back to him ASAP.

I think im going to tow it to the dealer tommorrow. I was hoping that with all the electrical issues going on that someone here might know whats going on. Im wondering if the car kind of lost the memory for the ignition keys.

sounds like maybe the battery connection came loose? im sure he pulled it off when doing that work and maybe didnt get it tightened enough. all those problems are from bad connection of the clamp to battery.

Well, after searching on this site and several others for several hours I found this thread on this site about how the ecm will go into LIMP MODE ..... https://www.civicforums.com/forums/3...ror-codes.html .... and it seems that the mechanic that put my timing belt on must have done the same bloody thing as in the thread. I went to him and asked but he wont admit to it. I was wondering if I should check anything with the altenator before the new ecm (computer) is installed so as not to fry this one as well.
