Cold Start Issues
#8
Found the broken wire!

I'll try and answer each one of your points..

1. Cleaned MAF with the CRC MAF cleaner
2. I have no Crank Position Sensor
3. With my header its not easy to see, but here's what I have for an engine code. 16 W 816451 The W is slightly marred (see pic) but I'm 95% sure that what it is
   
   

4. Checked all 5 gray/yellow wire grounds with my Fluke MM (I think its pretty accurate)
- Water Temp = .9 Ohms, Red wire has 4.14 Volts
- EGR = 1.2 Ohms, power is 4.45V
- TPS = 1.4 Ohms,
- Air Temp Sensor = 1.2 Ohms, power is 4.7V
During the initial tests my resistance test kept going all over when I wiggled the wire. I found it had completely broke inside right at the connector. I stripped it back and reconnected it with little clips for continued testing. It now reads 1.2 Ohms consistently. This might explain the error codes last night
- O2 = 1.3 Ohms
Was there a 6th?

5. Pulled my ECU out, (grounding myself) opened it. It looks clean on both sides of the board, no leaking Caps.
   
   

6. Reinstalled everything and reran the DLC test and now I only get CODE 12. I warmed up the rig for 10 min and that is still the only code. I will let it cool down and see if I still have cold start issues.

Thoughts on the ECU?
What is it?
What do you think of the engine code? Isn't that a 98? which doesn't make sense based on electronics

Also what is this? And does it need to be grounded?
