Cold weather car won't start

[Yellow302]

happens to everyone at some point. Mine is a little different.

number one, my starter was bad.

number 2 the car would start sometimes but not all the time.

The dead cold of winter must have been killing the brain in my alarm/keyless/remote start system causing the car to have no ignition signal.

I had to remove my whole system to rewire it. So far 3 days no more problems.

For my $3000 car... just need keyless entry now...

well i thought it was fixed

currently when the car sits outside in the cold, i have to hold the key in the start position for about 10 seconds before the signal gets sent to the starter. once it does its a quick 1 sec start.

When the car is in the garage (warm) or running with the heat on (warm). The car will start like there is nothing wrong.

Is my key ignition going bad and not making contact when it is cold?

I checked the white and pink wire and it was fine. It seems like its a contact issue.

Advice needed!

Try pulling the ignition switch and taking a look possibly??? its not hard to get to... put the key in the on position and trip the switch by hand maybe??? look up and make sure when you turn the key if the rod going to the switch is in working order

IMHO it's a battery connection issue. Clean the engine grounds and/or add another.

FWIW, most alarm starter kills are passive. That is, cranking power goes through the common and N.O. relay terminals. The only time the relay is active is when someone tries to start the car while the alarm is on. This keeps the battery from being drained.

i am thinking i might be better off putting the battery back to the front of the car. I have had nothing but issues with the car since i moved everything to the back.

Made the mistake of doing too many projects at once.

In the meantime can i tap a 12v line, tap the ignition, and touch the 2 together to get it running and bypass the key switch?

Kind of like hot wiring the car lol

anyone have an ignition diagram so I can start testing wires?

You can jump the little and big power terminals on your starter solenoid itself.

Easier is to remove the starter relay (in the underhood fusebox).

Be sure the emergency brake is applied and the car is in neutral. Once you remove the starter relay, look at it's belly and you'll see numbers. Use a jumper wire to bridge where terminals 87 and 30 would go. This bypasses everything up to that relay, and the relay itself. If the key is off, the engine will crank. If the key is on, the car will start (if it can).



Here's the ignition switch schematic. It's courtesy of bmac50.

Before I started doing all of that, I would grab a spare jumper cable. Use it to parallel your existing cables, until the car cranks. Whatever you're paralleling at that time is likely your deficient cable.

found it,

there was a splice into the white / pink line that was coming loose from the joint. i reached down to touch it while i had the key held over and she fired right up.

Thank god its nothing too serious
