No start issue

[Savagetwelve]

Is there anything I could physically do after installation to mess up the proper running of my truck? Since I installed it 2 days ago all I did was set it to program# 2 and set the tire size. I haven’t drove it much just a couple times up and down the block to test it and to move it around during the day.
Also this morning the auto start didn’t work for me! I hit the button but it would not crank?!?
This evening using the key drove down the block and stalled. The engine would turn over but not start!
I towed it back to my garage, disconnected the battery for now and I will try it again in the morning.
Any ideas?

I don't see how the addition of the Gryphon would cause this problem. My guess is, there's something wrong in your remote start circuit.

However, I WOULD set the tune back to stock - remember that you'll have to unplug the Gryphon before you reconnect the battery, then turn the ignition ON and plug the Gryphon back in.

See if you still have the problem at stock. If you don't, then Bill WILL have to get involved, since it's possible you have some corrupt files in Level 2.

Thanks Jack! I tried that today with no luck!

I was able to get it to start using program# 0, and the pedal to the floor to idle. The diagnostics showed me the following errors:
P1000: OBD system readiness test not completed
P2106: Throttle Actuator Control (TAC) system - forced limited power
P2135: Throttle/ Pedal/ Position Sensor/ Switch A/ B voltage correlation
P0121: Throttle/ Pedal/ Position Sensor/ Switch A/ Circuit Range/ Performance
P2101: Throttle Actuator Control (TAC) Moto range/ Performance
The dash displayed 'Check Gauges' and the wrench light was on!

I changed it to program#2 (with key in the on position I noticed a clicking sound in the engine) and was able to start w/o the pedal but the truck was idling rough!
RPM - 800 to 900 The dash still displayed 'Check Gauges' and the wrench light was on!
When I went to step on the pedal this time there was no response! I floored it with no change to the RPM's
Error codes this time:
P0121: Throttle/ Pedal/ Position Sensor/ Switch A/ Circuit Range/ Performance
P2101: Throttle Actuator Control (TAC) Moto range/ Performance

The last try after clearing the faults the truck would crank but not start.
Error codes:
P0121: Throttle/ Pedal/ Position Sensor/ Switch A/ Circuit Range/ Performance
P2104:

Just wondering if you know what these codes mean? Or if you have any tips that I could try?

Looking at a bunch of things here!

P1000 is because you put it back to stock and/or disconnected the battery so that's not the problem.

The other dtc codes all involve the throttle body or the pedal switch.

Sounds like this doesn't happen while at level 0?
Or does it now?

Try replacing the pedal switch?

Clean then maf with maf sensor cleaner?

Clean the throttle body?

BTW what's the year and engine size and milage?

Cai or not?

Right, Lars - it's not really clear to me though if the truck seems to be running properly at Level 0. It started, and since the codes weren't cleared, they were displayed. The last code you mentioned (I guess when it didn't start), was: P2104 Throttle Actuator Control (TAC) System - Forced Idle

So, everything seems to involve the Throttle Position Sensor and/or the Throttle Control, which makes sense because the throttle control relies on sensor readings to tell it where things are. Remember, there's no direct link between the pedal and the throttle body in our "drive by wire" trucks.

When it started in Level 0, did it seem to run normally? If it did, then I'd have to say there was a fault in the tune file. But I wouldn't expect a tune to muck with the sensor readings and it seems to me there's a "cause and effect" relationship between the sensor readings and the control positions. I do think Bill's tunes might bias a control value though. It seems a bit like a chicken and egg problem to me - which is first?

And, I just realized - you didn't say if you are running "canned" or "custom" tunes yet. I was assuming "custom" tunes. Which are they? Maybe, if it's canned tunes you could just update the "calibration" file using Pegasus. Looking at your Serial Number, I think you still have the canned tunes, right?

However, I DO think we need to bring Bill into this, so I'll try to do so.

Sorry I've been a bit unavailable myself - I'm dealing with the aftermath of a broken water supply line to the house we rent out and the resultant flooding of the interior!

(Are any of us having fun yet)?

Jack,
I will take the broken main over my service job right now of replacing mangled steel pipe due to a newb on a forklift!

BTW OP we do need that additional info?

LOL's

Ok so this is where I am at so far:

04F150 STX 4.6L w/ CAI
mileage: 60K
Running canned tunes just installed last week!
FYI - I cleared the codes each time before restarting above.

I haven't replaced or cleaned anything yet.

Today I tried blowing out all the connections with some air with no change.
The only 2 programs I used was 0 & 2 which both give me similar feed back.

Let me know if you need any more info?

[88Racing]

If you are getting the same results in both levels 0+2 then it could just be a coincidence that this happened?

Try all of these:
1. Clean the TB and MAF sensor. Use maf sensor cleaner.
2. The other thing is try and replace the pedal swicth.
They go out more than the TB.
3. Then if its not any of these then it may be the TB. But let's just hope its a gunky TB!
4. May have to replace TB.

Do these steps in this order. Then see if the codes still come up. Process of elimination.
Heck of a lot cheaper to do in this order also.

K thanks! I will let you know the outcome!

[88Racing]

Do steps 1-3 as a last resort do step 4.
Get yourself a hanes or chilton manual for your truck. It will be the best $20 you ever spent!
I think the pedal switch is available from Ford.
