Engine Shutdown

[bperez1977]

Hello,

 

I have another question, this time regarding a 2002 trailblazer. This trailblazer started to completely turn off when applying the brake, turning on air cond/heater, and of course sometimes while idling.

 

What could be the cause of this?

 

We have already cleaned the throttle body, replaced the fuel filter, air filter, new plugs, etc

 

Thanks in advance

What's the fuel pressure like? If the fuel pump is getting weak and not supplying enough fuel you could see it in those symptoms.

The brake thing is a "feature" on most remote start systems...And if one of those start to go haywire...It could do all sorts of wonky stuff. So that's where I'd start if I had a remote starter.
