Might be Onto something, these look rough... should I add some sea foam motor treatment regardless?

Roger, Wilco.

Spark plugs did jack shcit. Going to dump the gas tonight hopefully, and will report back. My wife is asking if I’ve got a separate relationship going on (kidding), bottom Line, thanks again, you rule. Going to get this mother trucker going eventually, then I owe you a drink of your choice at minimum!!

New gas seemed to help, but still missing something it seems. It turned over probably 3/6 times, got a decent idle up to 1050, then Stalled out after about 5 seconds. Going to add the sea foam now and see if that gives any boost.

Danm, tried a few more times and it turns over nice now but can’t hold an idle. Ok, now I’ll actually go add the seafoam.

Yeehaw, it’s running!
Idle is 1450, seems a little high? Sounds a little jumpy still, but we’ve got progress!

We are almost home Zim, once you are sure you have worked through ALL the old dinosaur squeezings in the fuel line, injectors and filter , it may be time to install BPS's 'special voltages' if that idle won't come down. Make sure your throttle isn't hanging up and check for codes again..

No codes, throttle doesn’t seem to be hanging up. I pulled the TPS voltage again today as a sanity check (doesn’t sound like the mixture is quite right) and I’m at .796 now! Wth, why does this jolt up like that? I would think a code would throw with it going high like that... makes me feel like I’m doing it wrong. The really really good news though, is that it’s starting up for me now, so progress is felt! Am I missing something or is time to bite the TPS bullet?

Zim, make sure you are getting the torx screw tight on the TPS . I would back the 'D' screw all the way off and remove the throttle cable and then check the voltage on JUST THE TPS. See if that alone has changed. If it has, it is new OEM TPS time.

Ok, tested, it’s new OEM TPS time.

before I tested, I took it out for an enjoyment ride / sanity improvement as it now starts right up (all you, thanks). Weird thing happened and don’t know what it means:

drove about 1/2 mile and brought it back to the garage. Parked, with my foot on the break for about 2 minutes while talking to my wife (in high gear) and RPMS started to go up to about 3500. Threw the parking brake and they dropped to “idle”, which has been about 1600RPM. Took the parking brake off and RPMS went back up. Did that a few times with the same results. The only way I could go reverse to high gear was by throwing the parking brake on for a second to get the“idle” to drop. I’m not sure the correlation between idle, throttle cable and parking brake, but it was a new one for me. Does this indicate anything other that WTphu?

zim, that is voo-doo with that parking brake thing snafu. Just FYI, if you are having high RPM shifting challenges, ALWAYS turn the key OFF.....then make the shift......then restart. Forcing a high RPM shift will KILL your transmission shift dogs. Anything over 1250 RPM @ 'idle' is 'to high'. Once we get a new TPS in there, you will need to check the clutches and the belt. 2008 was the first year of the one way clutch bearing . I am thinking with the ludicrous idle RPM that the clutch is kicking in the secondary clutch and when you step on the brake and apply the EB, it helps to drag down the engine. It will probably go away with NORMAL idle (1250 or under) RPM .

When you checked the 'TPS alone' , what was the voltage ?

.535 is the base alignment I get when I back everything off. I’m confident that screw was tight. I recalibrated again tonight while I wait for a sensor (I’m assuming that’s too much movement based on previous comments?). One thing I’m noticing is that she likes a little extra throttle. When I reset the TPS and re-tensioned, it cranked without starting again - the throttle cable was still a little loose so I put the 1/8” tension on and it liked that, and turned over. I can hear the knock in the heads that from what I’m believe is the case on cars, is air to fuel ratio (?), I played with the throttle tension a bit and if I go about 1/8 past taught on the cable, that’s the bare minimum to get it to turn over, and it tends to cut out and stall still. More throttle tension, and it starts right up and holds “idle” in neutral better, but it’s a very up/down almost like an engine rev while “idleing”. Since it likes the throttle tension, does that tell us it wants more fuel? Wondering if an injector is clogged up? Grasping a bit here as the small voltage increase surprises me that it would keep it from starting, but I know it’s sensitive.

Can't run with the throttle cable under tension or you will have crazy wild high idle regardless, especially once she gets hot. MUST have at least a 1/6" slack before the cable starts to pull it open.

If you want to add fuel and timing, Try Robbie's (BPS's) alternate 2008 TPS base and FLOW settings while you are waiting.

.580 base and .650 flow .

Just when I was losing hope, I come home to start to see if my daily prayers had any impact, and then checked the check engine codes to see if anything came up, code 21... any thoughts?

Zim, check the CRANK POSITION SENSOR harness . (passenger side rear of engine by the Stator harness) It could be rubbing through or the connection could be burnt.
I am still hoping you can get Robbies alternate BASE & FLOW voltages in there to see if they make any difference

Have not had a chance for the special tps recipe yet, probably tomorrow for that. I saw this when looking for the crank position sensor (is this it?) I’m assuming this last wire should exist?

Nope. Gear sector switch.......... The CPS is right where I told you and the sensor looks like this. You need to try the alternate settings or I am going to ........be busy.....
