2005 no start
i live in Australia
2005 C6 will not start
engine cranks, has fuel pressure, has spark, no injector pulse
all fuses checked out fine
any ideas would be great
thanks in advance

C5 Guy here but this applies not only to a C6 Corvette but also to a 4 banger Honda !!....so you checked for power (12v) at ALL the injectors (should be all the same color wires....mine are PINK and there are 1 fuse for each bank...INJR1 and INJR2) ??....good power to the fuses good ??...the injectors are "ground side switched" so with a 12 v test light connected to the battery POSITIVE the test light should flicker connected to the other wire (faintly but you'll see it) as you crank the car if the PCM is pulling the circuit to ground...is this how you checked the circuit or did you use a noid light ??...if you had NO spark also I'd say a crank sensor but you said the spark was OK...the only thing I can think of is if the PCM thinks the car is in "clear flood mode"....ie. you push the gas pedal to the floor which will inhibit injector pulse...if the TPS is sees more than 80% throttle opening...no pulse !!...if you have a scan tool you can check the TPS circuit !!

it was driving fine then stopped in garage
one hour later it would no start and shows the B3089 code for security system on tech 2
the only thing stopping it from starting is a signal to the injectors
thanks for your help 👍👍
power to injectors but no earth trigger to fire
checked injectors with tech 2 injector test activation and all clear but no signal to fire injectors on crank
Seems to have something to do with the security DTC B3089
so either,
Repair the intrusion sensor battery positive voltage circuit.
Replace the intrusion sensor if not a wiring problem (sensor is in the windshield upper garnish molding).
or replace the BCM if not the above problem.
2
Turn the ignition OFF.
Disconnect the intrusion sensor harness connector.
Probe the intrusion sensor battery positive voltage circuit at the intrusion sensor harness connector with a test lamp that is connected to a good ground.
Does the test lamp illuminate?

Go to Step 3
Go to Step 7
3
With a DMM, measure the voltage of the intrusion sensor alarm on signal circuit at the intrusion sensor harness connector.
Is the voltage near the specified value?
B+
Go to Step 4
Go to Step 5
4
Test the intrusion sensor armed signal circuit for a short to ground, or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?

Go to Step 11
Go to Step 6
5
Test the intrusion sensor alarm on signal circuit for an open or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?

Go to Step 11
Go to Step 9
6
Inspect for a loose or poor connection at the harness connector of the intrusion sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?

Go to Step 11
Go to Step 8
7
Repair the intrusion sensor battery positive voltage circuit. Refer to Wiring Repairs in Wiring Systems.
Did you complete the repair?

8
Replace the intrusion sensor. Refer to Theft Deterrent Sensor Replacement .
Did you correct the condition?

Go to Step 11
Go to Step 9
9
Inspect for a loose or poor connection at the harness connector of the body control module (BCM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?
--
Go to Step 11
Go to Step 10
10
Replace the BCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.
Did you complete the replacement?

Operate the system in order to verify the repair.
Did you correct the condition?

System OK
Go to Step 2
The Best of Corvette for Corvette Enthusiasts
still will not start but there are no codes now!!!!!!
All it is missing is a signal to fire injectors
it will fire up for a second if I put some brake clean in the inlet manifold
very confused
any ideas would be great
thanks


If your going to spray into the intake, I suggest you get a can of engine starter fluid to do it with.
The fastest way is to reflash the BCM with either TDS or just use Tis2000 to do this. During the firmware reflash, it will install the correct security key for the car so all the modules are hand shaking with the correct key.
Hence with the new BCM in play, but not re-flashed to the car, it's not correctly hand shaking with the rest of the module on the security key, and why the car is not starting.
So sounds like either a BCM or wiring problem to begin with, the New BCM solved that problem, but until you programming firmware flash the new BCM to the car, still going to have security key handshake problems between the major security modules.

i understand what you are saying
the problem is being in Australia there are no dealerships to go to
what is required to tie the firmware together
i could be the only person here who has a tech2 and candi for the corvette so not sure which way to go
hope you can help with some info
First, do you have a cable that will connect the tech II to a laptop running win10?
The cable that comes with the unit is a rs232 port cable, but most machines don't have this port so will need a ubs to res232 cable instead. So if no port on the laptop for the cable you have, then will need to pick up a Serial to usb cable.
https://www.automationdirect.com/adc...191e5bfac9c00e
Or this cable only since they are the only two cable that I know work,
From here, need to download and install VM player from the VM site to the laptop.
https://www.vmware.com/
Go to the right hand side of the page, click downloads and in the free column, will need to install workstation player.
The rest I will cover in IM to you on the TIS2000/ how to use it once you have the needed cable to connect the Tech II to a laptop. Hence we are going to use VM Tis2000 SPS programming to reflash the new BCM to your car, and should solve the no start problem of the New BCM in the car (to secirty key marry it to the rest of the car)..
The down and dirty, put the car into run mode/motor off by holding the bottom of the starter button in for about 10 senconds, connect a 10 amp charger the battery so we don't drain the battery during the flash, put the Tech II into pass through mode, and connect it to the car/laptop with the laptop on and the VM Tis2000 shell open. Click SPS programming once you have Tis2000 open in the VP shell, select generic pass through, Replace and program ECM, onboard and click next.
Now build the car in the next screen via the pull downs and click next.
Note, SPS will walk you through as well, but remember to select "Replace and program ECM" to start with since we need the flash to flash in the secirity key as well. If you select just program ECM, it not going to security key program isntead.
This will bring up a list of modules and we can to select BCM, normal method, and flash the BCM with new firmware.
Also in the list will be security module, but should not need to flash this too, since the BCM flash will security key marry the new BCM to the rest of the modules during that flash to take care of that step.
