cold outside can't start my evo
 

Guys what the hell happened.tonight was -2* next morning I couldn't start my car.motor was cranking but didn't fire up.shall I spray a little starting fluid or try to pull it with rope and put it in second gear.I have that car for 6 years and never happed before.I'm on 93 octane,basic modifications.the strange thing is that I drove from work and parked on my drive way like always.it drove fine,nothing was wrong.any input appreciated.

how old is your fuel pump?

My car takes ~3 cranks in cold weather, but i have a mini battery and actual e85, not e70 crap

Around 2 years old and it's wally.but is it possible that it died on me just because low temp?

You keep your car on the drive way as well?

Place the car on ACC and see if you can hear the Wally working. Also, if your battery is old you may want to try testing it. It could also be a bad ignition switch. Keep us posted and good luck!

Ok will do.also I'm planning to disconnect high pressure hose directly from the pump housin, start cranking and watch if fuel is spraying.I can do it at fuel rail but I think this way is quicker.

Update.just got home and it's around 14* outside.after cranking like for 15 sec car fired up.all I can think off is fuel got so cold that it was unable to ignite.thanks guys....or fuel pump about to say good bye.

Oh, put that isoheet or whatever it is called in the tank. It will start up better. Thanks for reminding me, ill have to do the same also.

Cool thanks man.

Your not going to hear the wally working until the car is cranking, being that the fuel pump relay is controlled by seeing a signal from both the crank and cam position sensor, as well as the ecu immobilizer. Unless of course the car was rewired for aftermarket pump applications.

no, mines in my garage overnight (but only sees about 40-50 degrees) but this past week in colorado its been under freezing. summertime it has no issue.

What spark plugs are you running? Had that problem last winter when I was running BR8es plugs, went a step warmer to br7es for cold months, solved my cold starting issues. This was on E85 if that matters.

Not true, with ACC on, the pump will come on if fuel pressure is low. The car won't crank if one of those signals is missing.

Br7es I have.but minus temperatures are gone and have no more issue with cold starting.thanks for asking.
