No, I was talking about your CTS wire, are you getting the correct feedback to your ECM?
BTW the CTS sensor on the head between cylinders 1 & 3 DOES feed the gauge not the ECM?
Both the 1 wire sensor and the 2 wire sensor are both connected. Temperature gauge actually works-ish. The gauge will climb to about 210° and then drop to just below 200°. It does this consistently at both idle and WOT. I don't see it as a problem.
@Nad_Yvalhosert: I hear ya with the CTS issues. Both are brand new and wired correctly. I do not have a scan gauge although I have someone I can ask. I'll get back to you all on that.
Now for the latest in progress. STILL will not start when hot. Ice cold, fires RIGHT up. I replaced the #6 cyl wire with a known good one from my Trans Am. Twisted the key and VVRRROOOOMMMMM!!!!!!!
I let it sit there at idle and got my timing light out. The base timing (with advance connector unplugged) was over 20° retarded!! I'm surprised it started. Sooooo, I twisted the dizzy CCW until the timing mark lined up with 0°, and the idle shot up from 700 rpm to about 1150 rpm. Then, I went ahead and plugged in the timing advance. The timing mark settled pretty close to the 0° mark and idle stayed @ 800-ish. I'm ok with that.
Granted, this was on a cold engine.
Now, I let it warm up to operating temp (while still trying to complete the break-in) and I got no backfires nor stuttering at all
HOWEVER, after a few minutes, even with the garage door wide open and a fan on high speed,
something smelled like burned fireworks, only worse, and my eyes started to sting. Then, I noticed that the cab was starting to fill with smoke - coming from the glovebox.
No fires, just nasty stuff burning off of the engine and there's clearly some places in the firewall that are not sealed. I'll have to fix that lol.
I have a carbon monoxide detector set up in my garage. It's been very reliable. Can't get the thing to shut up when the Wife's Buick is in there, sitting at idle. Never once went off with my truck in there. Ok so that just means the exhaust is doing it's job... but then where is that sickening smell coming from?
But, my original problem is STILL NOT SOLVED. I can't get this beast to start when it's hot.
Oh, and btw, I don't like how far CCW I had to rotate the dizzy to get the base timing to 0°
Right now, it seems that symptoms and suggestions point to a CTS and a new ICM in the distributor. Yes?
