Change guage package--Truck no work?

[fly912]

I know,I know, first post. I'm the newbe... Got a Q for the vets here.

I have an 01 Duramax with no mods that is giving me fits. It was a work truck and I am trying to polish it up a bit. Ran fine yesterday, did some work on it today and now won't start. I have been searching on here for about 4hrs and not finding anything that is fixing the problem.

This is what I did:
Tore the column apart, replace blinker/wiper switch, replaced shift lever/mechanism, replaced broken gauge cluster. All parts from an 03 D-max. finished swapping parts started engine, ran for 5 seconds and shut off.

This is where I am at and what I notice:
Hit lock button on key fob-security light is solid-relays click-locks inop, hit unlock-security light is blinking-relays click-locks inop, turn key on security light is replaced by obnoxiously bright battery light. When glow plug cycle complete, battery light goes out and comes right back on. Batteries are good, all fuses are good (under hood and in cab).

This is what I have done:
I tried the 3 cycle,10 minute with cranking emergency relearn, I tried the 3 cycle, 11 minute with "on" only (no start) emergency relearn, I've tried putting my broken gauges back in-----all of this has the same result, nothing. One thing I notice when doing the relearn, the security light is not on, the battery light is on and at the 10min or 11min mark, the battery light does not go out. I don't think shift lever mechanism or blinker/wiper switch could be the problem. Do you?

I have not changed the ECM so I'm not sure a relearn is the problem? After what I have read, I am however guessing that the gauge swap will affect things with the ECM, not sure how. What the hell am I missing? Do I need to have flash done and not just a "simple" relearn? I know the security thing is a mess just from looking at it. I havn't ruled out fuel issues yet either, but my guess is the security bit is the problem. One more thing, when I purchased truck, security light was blinking when drivers door was open. Off all other times. Sorry for the long post, but thanks in ADV for the help.

Have you tried starting the truck in Neutral

 

[sweetdiesel]

Im thinking you have a security issue and are going to needs osmeone with EFI or a tech 2 Hopefully I am wrong


The shift lever is showing that you are in park ( not blinking ) Correct

 

[fly912]

Just tried to start it in neutral, no luck. Yup, the shift lever is showing that it is in park (no blink). Electronics for lever are working correctly as far as I can tell, engine only turns in "P" and "N" as it should. My guess is the security thing as well, especially because the door locks are going haywire as well.


Anybody in the Denver area have an EfiLive or a Tech2 and want to earn a few bucks teaching somebody how this is done?

 

[duratothemax]

you need to mate the new passlock sensor to your BCM.

Tech 2 is needed

 

[fly912]

right on. I will check around and see what I can find. Somebody will have a Tech 2. Thanks for the info.

Off topic but how did you get a gauge cluster for an 03 to work in your 01. Arent thay different as thay changed the body style in 2003?

Yeah, I don't think that would/should work right . It's more because of the electrical changes made for the 03 MY than anything else.

 

[Vrabel]

did you short something? check your fuses.

 

[duratothemax]

03 cluster will NOT work in an 01-02 truck.

 

[fly912]

Cluster fits fine, plug is the same, gauges are all the same. Thought it would be fine. I did check all fuses. I will go back and see again tonight. This is what I am going to do: put original gauges back in check fuses, try to start. Original gauges are broke, but truck still worked/run.

Will reply back tonight.

yes it will physically fit and yes the plugs are the same. The wiring configuration/pinout on the connector is completely different.

The gauge clusters are indeed not compatible between the different gen's. I put the old cluster back in and still have the same results as with the 03 set. I am guessing I am now down to having the VATS fixed/flashed? The dealer charges $100. I can live with that I guess. Got to learn the hard way.....


Question for ya: are all the pins the same just in different positions? Anyone got a schematic....

they are not compatible in any way, the wiring itself is different/data bus, etc... swapping pins wont work unfortunately.
