RR not re-booting?

[mr.prick]

looks like i spoke too soon,
once i start the car flash scan looses connection and
the car run very poorly and won`t stay running.
also the RR will loose connection.
after a few tries it went back to not cycling the fuel pump.

[mr.prick]

i have tried all the easy fixes i can think of,
the windows, stereo and lights work but the fuel pump is locked out.

can someone confirm that flashscan will not be able to
connect/retrieve ECU info (VIN and tune) if the BCM is DOA.
i can`t down/upload or read the VIN with the stock ECU.
the RR connects, reads writes but will not update which is
a mute point because when i did get the car to idle it only did so
for maybe a minute then when kaput.
the fact that the RR can do everything but update seems to
prove it is vehicle (BCU?) related.

If you read my post from before, I could read/write, but could not update
the road runner realtime. This was the CABLE CONNECTION problem, a problem that starts at the round connector and ends on the RR board. AFTER I went DIRECT mini-usb (which is built in the RR Board interntallu), I completely got all functionality back. I was advised to do this by Craig M, because I could not connect via bluetooth and could not real time read/write w/the cable. He stated this is a known problem and that by bypassing the round connector, all would be fixed. It was.

By the way, I'm not sure what the deal with yours is, just passing on some useful info.
ANOTHER THING TO CHECK!! I sprayed my original RR w/hosepipe by accident washing my car.
Make sure next time its out there is not water in it. This killed my first RR. The 3v lithium battery on the RR circuit board was dead to name a few problems.

the RR works fine, because of the fuel pump not "cycling"
i thought the RR was not rebooting (hard reset), so i posted here.
when i hooked up the stock ECU the fuel pump cycled and i thought all is well
and reconnected the RR, i then started the car and
for a few second everything seemed to work fine but,
i could not update, then the connection dropped and the car
started to miss an died.
with the stock ECU i could not read or write or retrieve the VIN status.
this is what make me think it is BCM/VATS.
fbodies are notorious for the BCM, key and (or) the ignition tumbler going bad.
all fuses seem to be fine and i only unhooked the injectors harnesses
when i changed them, so it is not an unhooked connection,
i think just a coincidence that all is going wrong immediately after the
change of fuel injectors.
if the BCM does indeed lock out the scan tool, i pretty sure
it is the culprit, but i would like to be sure before
dropping $150 for a new BCU.
like i said everything else works.(stereo, lights, windows ect.)

FWIW i changed {G1201} to none, and that did nothing.
from what i`ve read it`s not that simple to bypass the BCM.
why i was able to reconnect to the fuel pump for a short time after
hooking up the stock ECU the reinstalling the RR, i think that was a fluke
because it was all but a minute and then it is back
to being locked up.(fuel pump)
i have seen someone de-solder the relays in the BCU and clean off the connection, then re-solder it back together.
i do not have the tools/know how to attempt that.
i wish we could do something with the BCU.

i got all discombobulated when i first started to try to update with the RR,
thinking the car was running poorly due to needing VE adjustment
for the new fuel injectors.
it wasn`t till your recommending it was reduced power mode
i started looking elsewhere.

does anyone know how i would be able to "test" the BCM or
if this sounds definitively like a failed BCM?

Hmmm...when I first installed my RR 'guts' kit...I had one badly soldered foot on the RR PCB header. Truck wouldn't start. Everything worked 'except' the fuel pump.
I told one of the guys on here what was happening and his first question "does the fuel pump prime?".
So...if there's a problem with the soldered connection/chip....everything seems to work 'except' the fuel pump.
Also...after finally getting it running....I'd be driving along RTACS'ing and when it would 'drop out' the truck would hicup...and sometimes die. I always managed to get it going again though.

This is what I did today...we'll see how it goes tomorrow!

i know the RR is working because i can connect/operate it.
as for the fuel pump being cut off during priming, that seems to be intermittent.
the stock ECU connects but can`t down/upload or retrieve the VIN.
it freezes while logging, so the RR drops out.
i`m trying to choose between the ignition tumbler, the BCM or/and the OBD2 port
as the possible culprit.

passkey relearn:
after clearing the DTC`s,
turn the ignition switch to the “On” position for 11 minutes,
then turn the ignition switch off for 30 seconds.

Mr.Prick, what car do you have...?

On some models yo have to repeat that two more times (total of 33 minutes).

i have an `02 camaro.
this worked for me last nite,
but now the car is down again.
it will crank, but not start.
i can give it gas while cranking and it will start but
run extremely rich and die almost immediately.
i seem to get the P1626 DTC intermittently and i am wondering now
if it my ignition relay or something other than VATS.
the fuel pump primes when the key is first turned, but after it stops cranking
it will re-prime.
like turning the key on and off, then on again.
this is not from the RR, the stock PCM does this as well.
i am just trying to figure out why i can drive the car a few times then have to go through this again.

Regarding PASSkey/VATS/BCM:

If you crank and it does not start, turn key all the way off before trying to crank again...
this will prevent PASSkey learn mode from initiating (when initiated it won't let you start for 11 minutes, and if you do try to start the 11 minutes starts over).

The unfortunate thing is, on F-bod the BCM is not on the serial bus so we can't see what codes it's throwing.
