Conditions in which remote start will not work
The vehicle's key is in the ignition
The vehicle's hood or doors are not closed.
The hazard or warning flashers are on.
There is an emissions control system malfunction.
The engine's coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts have already been used. The maximum number of remote starts or remote start attempts between ignition cycles with the key is two.
The vehicle is not in park.

Does the alarm randomly trigger itself?

 

Yep, those are all the conditions that I mentioned that I’ve made sure are met, I saw you posted those on other threads. And no, my alarm does not randomly trigger itself

 

The hood latch sensor seems to be a frequent culprit. In that instance, normally the alarm randomly triggers itself.

 

Yeah my alarm doesn’t do anything and I feel like my car wouldn’t even attempt to fire if that was the case, is it possible that these cars have a sort of “valet mode” that would prevent remote starting? My dad used to own a Charger that got stuck in valet mode and couldn’t be remote started

 

Awhile ago, had an intermittent check engine light. When the light was off, the car would do as above and oftentines not start. Other times it would start and immediately shut off. Always knew when the code was present rather than pending if the remote start worked or not. The system tests, detects a fault and shuts the car off.

 

Get a scanner that does body codes also and check which code/s are stored

 

My car had a CEL for a purge valve, I replaced it and cleared the code, hasn’t come back since and has resolved any purge valve issues I was having from before, this remote start issue has been a thing since I got the car however a month or two ago I got a big red X saying contact dealer which I can’t scan for. My car runs perfect so I have no idea why it’s giving me the big red X and I don’t think it’s remote start related either considering my remote start issue was a thing long before the big X showed up. I’d be able to get my hands on a big scanner from the shop I work at so I’ll probably go that route and scan any possible codes. The “fault codes” that are present on my car are the big red dealer X, traction control off, ABS fault and the infamous TPMS light. No CEL or anything like that.

 

I'd go with Pony Man's suggestion of the hood latch sensor being outta wack somehow.
I've never used the remote start on mine, she's been a garage queen since I got her.

 

Since the car allows the remote start function to go for a start, it sure thinks everything required is correct. If you had a flaky hood latch circuit, maybe just the starting of the engine (with its subtle vibrations) is enough to make the latch send back the wrong signal back to the BCM. Or the oil pressure is sluggish to get its psi up to snuff. Neither one of those conditions would prevent a normal ignition key start (but force the remote start cycle to terminate itself). Its easy enough to verify or eliminate the hood latch, by jumping the 2 wires at the disconnect connector talked about in several history threads (unless one of the high end scanners see's what the problem actually is).

 

That sounds like it could be the cause, I’m all over the place right now but I’ll probably be able to test that theory later this week so I’ll let y’all know how it goes, thanks for the info

 

Remote Start not working

Let me preface this by saying I've searched and tried almost everything with no luck. I can't get my remote start to work, '09 GT. Lights flash but the car doesn't turn over when I hold the start button. I have a brand new Deka Intimidator battery that I need to install but after that I'm at a...

Had same EXACT symptoms, bypassed hood latch, remote start now works.
