Half finished system? Take a pic and caption the position/next step. Can't hurt. Too many irons in the fire and someone always gets burned.
This is solid advice! @everyone should heed, life is on the line and it isn't necessarily yours.One thing I did was a nut and bolt check everything before my first drive. I was so afraid I forgot to tighten something. I just wanted make sure was done right.
Yeah the idea was just a dash indication of concentration rather than testing a sample every time I fill up but it will also serve as an indication of water in fuel and give me accurate numbers to use for tuning.Why would you not simply put it inline? Is that not how GM did it on flex fuel vehicles that actually used a sensor?
I don't know that there is a way to tune an E69 ECM for truly being flex fuel, at least with HPT. Have you figured out a way or just going to run different tunes?
I guess I wasn't entirely clear with my initial post. I wasn't sure the sensor could take injection pump pressure, I had looked up installation and inline on the return side or supply for carbureted systems. I don't want a catastrophic failure/fuel leak especially 16" behind my head so I tried to look up pressure ratings and couldn't find any, E-mailed Innovative Motorsport and got a response today. They also don't know pressure ratings, they use a continental oe part and ratings are not publicly available.Yeah the idea was just a dash indication of concentration rather than testing a sample every time I fill up but it will also serve as an indication of water in fuel and give me accurate numbers to use for tuning.
I don't know why I didn't think to just put it in line with the fuel delivery.. I want to put it on the high pressure side to watch temp before injection but no way it can handle it.
Gotta love it when they sell parts that they don't know specs on. Or when you have to cross reference websites to get 1 complete listing.I guess I wasn't entirely clear with my initial post.

I was just curious what the temp is after running through the HPFP, and if that had a noticeable effect on power.Why are you wanting to measure fuel temperature anyway? What are you doing with that information? And how would you make the connections on the high pressure side that would not leak?
Force them down and to the passenger side of the engine, they kind of just hangout there against the subframe. I don’t think I zip tied anything but can check tomorrow when I am home and send you some pictures.View attachment 51924
This seems like a problem routing them under the exhaust pushes them fwd to where the shifter is under the gauges,
to me the cables seem too long unless I'm routing it completely wrong
Are you seeing normal start up functions? Fuel pump priming, throttle body reacting to pedal, information on the dash? I have an 06’ SS so will probably be different than yours, but there was a connector I did not plug in. It caused my dash to have a power steering message and it would not crank even though the starter could be jumped to crank.went for 1st start today and got a no crank starting troubleshooting that now
EDIT: Anybody have any good places to start?
so far I've verified the the starter relay has 30A12v supply and when jumpered the starter turns over so no request to crank.
I switched the clutch and brake wires and tried every combination of off/on there.
All data doesn't have much on no start for the cobalt, I'm still searching online other places but if there is already a list here somewhere the forum search didn't pull up for me it would be helpful.
This forum has changed so much since I started my build an I never get what I expect from the search function.
