Intercpetor-X cold start in winter time
I have not been able to get my car to start and its currently 32 degrees fahrenheit.
I replaced my coils with the mazsport ignition solution. I performed the de-flooding procedure and replaced my spark plugs with new ones and it still won't start. I am starting to think the interceptor-x is causing my cold start issues. I think it may be adding too much fuel. Am I on the right track? :dunno: |
your car didn't start, then you replaced the ignition system and it now still won't start?
By adding another variable to the equation, now you must make sure the coils are hooked up properly since they too can prevent your car from starting. |

I installed the new coils myself and took my time double checking everything so I am confident that it's properly connected. |

I am basically asking what I should adjust in my EMS to make cold starts easier.
The 91 octane base map is not designed for Canadian winter weather so this must be part of the problem at the very least. |
Sounds like the interceptor is draining your battery. Time for a new battery. Or you have to install a switch that will let you turn it off when you shut off the car

More than likely your coolant correction map is jacked

Look into your crank map, water map, and air map.
I'd begin with the crank map. Save the map as you originally have it into a separate memcal, then go to the crank map screen and at the temperature it is set try to pull back, or add some fuel. once the car starts before it gets hot watch your AF and see that the motor is running within acceptable ranges. If not, use the water map to adjust the fuel as necessary. Do not do the adjustments while the motor is flooded though. First you need to pull start it, and let it run for a while, to clear up. Then let it cool down and then try it. |
Thanks for the tips!
I can't find anyone to pull start my car so I need to get it started normally. Here are my air and crank maps. http://www.turborx8.ca/pictures/screen21.jpg http://www.turborx8.ca/pictures/screen22.jpg |
air will go kinda lean at -25 lol
Can't tell you anuthing by just looking at the maps. Without the AF ratio they mean nothing. how is it a cold start if your coolant is 65C degrees hot? |
before you do anything, why don't you just unhook the Int-x and just connect the OE ecu to see if it starts. that way you 've eliminated the Int-x entirely without having to run around looking in the wrong places.

To keep it simple, should I just pull the fuse that connects power to the int-x from the positive battery connector? |

I tried pulling the fuse on the int-x and it was even worse. :(
|
did you try just unhooking the x all together? or you just pulled the fuse as stated.

Do I have to remove the whole thing to enable the stock PCM? |
I had the same problem until I started to turn it on for 15 everyday (if I don’t drive it of course)... I think the Interceptor doesn’t like cold weather at all. The longer your car stays off the harder it will be to turn it on (cold weather) at least that is how my car is

in your situation I would totally start from scratch. reset the pcm while your at it.
What is the procedure to reset the stock pcm? |
do the "hard reset" by disconnecting the negative on the battery. you know there is a "search" feature on this forum. it's a free service.

Do you have stock injectors? If you don't...you will flood it bad if you try and start it on the factory injector maps
I would find someone to pull start you i you think it;s flooded........otherwise it might be a really long and frustrating process. You might want to hook up an inductive timing light and check that you have spark as well |
Remove the Int-X entirely and then try starting it with the de-flood procedure.
Pulling the Int-X fuse just ensures that it wont start. |
