Man i am really frustrated guys. I have an LT1 scanmaster on my car. I installed a couple years ago. I bought the scanmaster before they had the plug that went with the cord, so i had to hard wire it into my OBD2 connection wires underneath the dash.

Ok to the problem. The scanmaster is not reading anymore. Now i know that the problem is not from the scanmaster because i tried to plug up an OBD2 scanner and it will not read.

I am sure that it has to do with the wiring around the OBD2 connector.
I tried to remedy this and only made it worse. I wound up cutting all of the wires that go to the connector , and extending them with more color coded wires to give me more room to work with the plug. I have reconnected all of the wires a couple times now. I have not reconnected the wires back to the factory way because i cant really get enough wire and room.

I am kinda screwed as i dont really know how to diagnose the wiring underneath. I have a voltmeter and i was just going to go from wire to wire and make sure i am getting the proper voltage from each wire.
Does anybody know how to help me diagnose this problem.
I feel retarded because i was trying to do something to help read my car better, and now i cant read it at all.

I have switched PCMs after a mail order tune, so i know it is not the PCM itself.

Please help guys as i really need to get this car scanned and properly tuned. I am getting cam surge and cannot get dyno tuned untill this gets resolved.

i have a scanmaster that is hard wired as well (well kinda, i spliced it in with male and female plug ends so i could take it out if i wanted). anyways if i want to plug a scan tool in my obd port i had to unplug the scanmaster to get a scan tool to work. so what i mean is it could be your scanmaster just took a crap on ya and your scan tool was not reading because of the scanmaster. btw i hate wires as well

I totally appreciate the reply being nobody else answered.
Yeah well i took out the scanmaster after it stopped working. I think the wires got tugged slightly and thats why it lost connection. I did however try to hook up the obd2 scanner after the scanmaster was dissconected.
I have read that some people put a toggle switch to turn off scanmaster for scanning ect, but i didnt get that far.

No I dont at the moment. I pulled the system because i am porting my heads and slappin them in. Thats why i am trying to get this scanner thing worked out so i can tune my car better. I have a mail order tune but i am thinking i need more fine tuning, because i am getting surge and all that crud.
