Vector ECM Problem

	Jackknife Member Join Date: Sep 2006 Location: Hot Springs Village, AR	Received my re-flashed (back to stock) ECM from Vector today and installed it in my car. Turned the key and the car "lights up" but won't crank. Tried to call Chris, but he doesn't answer his phone...sent email also. While I'm waiting, does anyone have any ideas?

Per Solstice Service Manual page 10-86: If the ECM is replaced a CKP Variation Learn Procedure must be performed. Refer to Crankshaft Position System Variation Learn on page 6-553. Page 6-553 is devoted to how to perform the learn. It requires a scan tool, to see if the P0315 was successful. Dealer does it, unless you have a good scan tool and the procedure. __________________ VIN #4744, Cool, Deposit 5-28-05, Delivery 12-10-05 VA/MD/DC Solstice Club solsticeclub@yahoo.com ~~~~~~~~~~~~~~~~~~~ Pontiac builds excitement...

Another is that besides the crank re-learn there could also be a security learn. __________________ #118042 11/18/06 GXP Mean Darkside loaded wo On-Star MODS: ED IC Pipes, Dejon IC, Magnaflow Catback #1922 12/03/05 Mysterious Steel/Sand w/ 6-Disc Monsoon Conv., Pwr & Premium Pkgs A/C LSD Carpet Mats MODS: GM CAI & CATBAck Dover DE ~~~~~~~~~~~~~~~~~~~ Pontiac builds excitement...

Wouldn't you think Vector would do this? When they did my original re-tune a crank re-learn was not necessary.

Not sure the procedure, but I'm sure a little searching should come up with it. __________________ 07 Solstice, black, 5spd manual, convenience, preferred, and premium packages, LSD, Monsoon, XM, A/C, ABS, chrome wheels.

Jackknife We were out to lunch in meetings most of the afternoon so far, you probably just have to do the security learn. I believe that info was included on the sheet with the unit when it was returned. __________________ Chris White www.GTOShiftLight.com Home of the first 2.4L and Kappa tuning! 2006 GTO MXO Spice Red 2008 CTS4 3.6L DI 2008 Malibu 3.6L 2008 Trailblazer SS 2008 CBR600RR

I believe that info was included on the sheet with the unit when it was returned. I've tried the security re-learn...no help. The security light stays lit...the car won't crank. BTW, there was no instruction sheet included w/the ECM. I'm waiting for Vector to suggest another course of action.

	Jackknife Member Join Date: Sep 2006 Location: Hot Springs Village, AR	Well, here it is 6 PM, CST and no word from Vector since 2PM. My car still won't crank, won't take a security re-learn and the fuel pump module in the fuse box clicks away continuously when the key is on "ON". I hope tomorrow is a better day...Vector, are you out there? Jackknife __________________ Deep, Ebony, Loaded...VIN 2124 DDM Supercharger #6 Stage II Intercooled Magnaflow Dual Cat-back ...

Still no good

Jackknife (waiting for Chris to step up)

Have run into this with other GM ECM's, only 1 Bosch-duramax. The only fix was ECM replacement. Have tried to reflash problem ECM's but to no avail. Root cause was almost always external electrical fault (just boosted from or to another vehicle, faulty charging system, shortcuting repair/replacement procedures, etc..) What procedure did you use to reduce the chance of ESD (electrostatic discharge) during ecm removal & replacement-possible cause.

Depending on what was changed during a reflash a security relearn may or may not be needed, engine will crank & fire up but stall-cuts injectors. As a matter of practice I always do a c
