I am having a problem with my car not starting and i think a wire came lose on the ecu. I was looking at it and i noticed the wire on pin 15 looked a like it went to something before but now it doesnt. I was wondering if anyone could help me out. I have an ecu printout but i was still a little confused as to where it might go. Thanks for the help

that wire is not your problem because that wire is not needed. that wire is tx data..if you give us some details of your problem we can all help you out better..does the car only start at certain engine temperatures or is this a constant problem etc..let us know

Well i didnt really think that was the problem. I worked on it a little today. I changed the plugs and it ran ok for the whole day and then i went to start it and it wouldnt turn over. I checked the plugs and they were shot and smelled like gas. I put new plugs in and the car wont start. So i unpluged the injectors and tried to start it like that because i thought it was flooded real bad and it starts and runs for a couple of seconds and then stalls. So i hook everything back up and it wants to start and it almost does but it just wont turn all the way over. Any help would be great.Thanks

so your getting spark even for the times that your engine doesnt start? sounds like your injectors are staying open too long or at least one or two of them and causing your engine to flood. are any of your spark plugs blacker than the others? say #1 blacker than the rest? if so then check that spark plugs fuel injector it may be the culprit. take the fuel rail off with the spark plugs still hooked up and in the fuel rail. unplug the coilpacks and turn the key on to build fuel pressure then turn try starting the engine..of course it wont start because of the coilpacks but this way you can see if any of the injectors are staying stuck open.

i took out the injectors and one of the o-rings on the top had a little bit of it cut up.

the very top o-ring? i dont think this is the problem, is it severe? you can always get a new one and try it but i dont think thats the problem..check your ecu for codes
