No crank, no start

Diagnose and fix a no crank, no start condition

What causes an intermittent no crank, no start?

GM has issued a service bulletin on the vehicle listed below to address a no crank, no start condition on many of their late model vehicles with push to start features. In addition to the no crank, no start you may also encounter an intermittent security light on condition, a “no remote fob detected” condition or a “poor or no remote keyless entry range” condition.

Symptoms covered by this service bulletin

GM states that you may encounter any of these issues.

• Intermittent no crank

• Intermittent no start, or start and stall

• Security / Theft light / Message

• Poor or no RKE range

• Keyless or passive entry/start inoperative

• No Fob Detected message

• Service Tire Pressure Monitor message

• Trouble codes B3055, B3060, B3935, C0750, C0755, C0760, C0765, and/or C0775.

What causes the trouble codes and no crank, no start?

The starting, security and tire pressure sensor systems all use Radio Frequency (RF) technology. GM has determined that some aftermarket devices can cause Radio Frequency Interference (RFI), which can “jam” the radio frequency being transmitted and cause all these symptoms.

Before you take your vehicle in for service, check for the presence of any these aftermarket devices in your vehicle:

Vehicle immobilizer keys from other vehicles

Keyless access transmitters from other vehicles

Interstate/bridge toll passes

Gate/door passes to allow access to pools, driveways, entry doors, etc.

Community/parking access cards

Fuel station speed passes

Building access swipe cards/ transponder devices

Customer added LED bulbs in the dome, tail, turn, stop, strip, floor, door, or head lights. These added LED lights can cause RF interference when they’re turned on. For example, when you operate your remote keyless entry fob, it’s normal for the dome lights to turn on. If you’ve replaced the dome light bulb with an LED style bulb, the new bulb may emit an RF signal that jams the security feature of your GM vehicle so it can’t recognize your key, causing a no crank, no start condition.

In addition to the items listed above, RF jamming can also be caused by:

• Certain cell phone chargers

• USB power banks

• USB flash lights

• Fans (12 volt or 110 volt)

• Any type of USB, 12 volt or 110 volt chargers

What to do if you have a no crank, no start problem

First, remove all other transponder keys from your keychain. Then disable any aftermarket LED bulbs you’ve installed and disconnect aftermarket phone chargers, voltage inverters, USB devices plugged into your sound system, USB power fans, USB battery backup or USB thumb drives. If the vehicle operates normally, you’ve discovered the source of the RF jamming.
