Aww I thought they were powdered from the start? What color did you go now?

Basically the same. Super bright yellowish green. Just not AS green as before

 

[Kenny123]

So we wired the goblin up today. Plugged as much in as we could possibly do. Everything looks like it should work. Turned the key and the lights came on. No engine cranking. Been looking EVERYWHERE for a potential ground missing. Nothing then I see this ground wire on my bench. Any idea where this bad boy goes?

 

[Ark :D]

It goes from the grounding lug on the engine support to any bolt on the engine. Did you clean the powder coat (or paint?) of the engine supports before mating the engine to the frame? If not, you definitely need that grounding strap.

Thanks man just did that and still no start. Hmm. I hear the pump come on and the relays clicking but no power to the starter.

 

[Mayor West]

Did you hook up your starter correctly, and the lil single wire to the lil hole? Pics?

 

[Kenny123]

Yah I think so. I'll post pics now. But also can't for the life of me find where some other plugs plug in. I'll post all plugs as well if anyone can help. Sorry to be so needy but I wanna hear thus SOB fire up.

 

[Mayor West]

Do you have a security light on your desk? Lock and car yellow icon.

 

[Kenny123]

Also this plug. No clue

Only when you first turn the key is that lock light on. Then it clears.

shyit my bad, that small white plug is for the ambient light sensor.

i think the black is for that little white box next to the bcm and purple I THINK is power steering related but could be wrong

Defer to Lonny

Also this plug. No clue

Based on it's location this is for your coolant overflow tank (bottom side - also wont keep you from starting)

Do you have 12v at the starter and relay box pole?
Did you connect the 15amp fuse to the battery?
Does your fuel pump turn on and throttle body open/close?

 

[Ark :D]

Turn the ignition on and make sure the shifter is in neutral, then jump the starter with 12v straight from the battery. Does it crank?

 

[Kenny123]

So thank you all for your help. I actually did find the issue and I got the engine to crank now. Did forget to tighten the lower compression nut on the high pressure fuel pump so I KNOW I have gas hahaha. Not sure about spark though. Gonna mess tomorrow. Another oddity is I turn my key and I can let go and I still cranks until I physically shut it off. Its a brand new starter too so I can rule out starter solenoid.

 

[Lonny]

Four pin white plug is for the boost gauge.
Black with blue is for the small light gray box that mounts beside the BCM. It is the tire pressure monitoring receiver.
The pink and blue is for the brake reservoir.

Mine does the same thing. It stops after like 8 seconds or something like that. I think it's just a Cobalt (or a Chevy/GM) thing.

Also, my car runs for a second or so after I turn the key off.

I had the same problem with it running for a few seconds after the key is shut off. I found this fix in a Manny's City Goblin thread

Seems to be a common problem, as several other build threads also indicate getting only 3psi boost after getting their cars on the road. You may want to search for them to see what remedies may have been implemented. I figured it out. It was a solenoid that I removed thinking it was part of the...

Ok so I ended up buying a nice OBD2 scanner. Plugged her in and just like I assumed I had a fault in my crank position sensor. Replaced it and car fired right up! 1st start is done!!! Only issue is she shuts off IMMEDIATELY after it starts. Other codes are P0452 (FUEL TANK PRESSURE SENSOR LOW VOLTAGE) as well as P0449 (Evaporative emissions vent solenoid valve control circuit.) Also lastly P0238 Turbo boost sensor high voltage. So let the digging begin.

 

[Ark :D]

Does it continue to run if you unplug the MAF sensor?

 

[Kenny123]

Sure does. I just tried that and it runs!! Turned it off immediately because we have no coolant yet but I assume once we to our intake and turbo piping she will run like a dream.
