Okay guys and gals, my trouble code light was one, so I connected a paper clip to the a and b terminal of the obd1 connector, and... My fan turned on. 12 code flashed but I got nothing else, and the light stayed on. Any advice is greatly appreciated.

 

Hard to say, the fan turning on with AB jumped is correct.

If there are any other stored codes other then the 12, they get blinked out after 12 has been blinked three times.

So the fan is supposed to turn on when checking for codes? Huh. Alright. Could it be the ecm? My trans am wont start right now. I just replaced the fuel injectors (Bosch 3 19lbs) the fuel pressure regulator (Southbay adjustable), new spark plugs (Bosch) and msd wires, plus slp runners. My fuel pressure is slightly low (38psi), but it should still start.

 

Can one of you guys give me the correct ohms that the maf sensor, tps at idle, and the the ecm give back or a way to check the ecm if it cannot be checked this way. Thanks.

 

The TPS at idle should be at 0.54 volts. MAF can't be checked unless the engine is running. And the MAF isn't used during cranking.

Did the engine ever run after replacing the above parts? If not that is what I'd be looking at.

Youre a life saver. The engine ran alright before replacing all the parts that I added. The injectors were junk though, malfunctioning.
