Can a faulty TPM (tire pressure sensor) cause a fail start? I have a 2013 RT Hemi and we recently had the tires replaced at Discount Tire about 2 months back. A couple weeks ago the light for the sensor and the alarm for the sensor went off, it didn't last but a couple seconds. Ok cool, we blew it off. Then it happened a few days later and blinked, then stayed lit for about 5 miles. So I took it to get the pressure checked. Two were spot on and the other were 1 PSI over. The dude said it could be the sensor if it stays on, and it's the pressure if it blinks. We laughed it off cause he said or it could be the weather it's been over 100 for weeks.
Well it didn't happen again. But today the hubs goes out to start my car and it cranks but doesn't start. He tried this a couple times then I went out to pop off the start button so he can manually start it and it starts with a red dot on the dash, then the dash reads to CHECK TPM SYSTEM.
I would appreciate some input from yall on the issue if you've had it before and whatnot. Thanks-Mel

It's not possible for a faulty TPMS sensor to cause a no-start condition. The starting circuit, ignition circuit, and fuel delivery circuits are in no way dependent on the proper function of the TPMS system.

However, I can't rule out the possibility that it's a related symptom. Such as a problem with the CAN network that is taking down both the WIN module and the TPM module. For example a pinched harness, poor connection or ground that both those systems share, etc. That is just a guess though. A red dot would mean something like a security issue, wrong key, etc.

Your best bet would be to get it scanned for codes and go from there.

TPMS is a stand alone system, it will not affect other systems. A bad wheel speed sensor is another story. When one fails it takes out traction control and cruise control. Neither would cause a no start....
