    It took me 3 hours using a forced air heater at 50k btu's to get my 04 explorer warm enough to start, it does have a block heater ECT, and now has a battery heater since it got as cold as -47 below zero up here in fairbanks alaska, if anyone has this problem get a battery heater use the heater pad not the heater blanket, also just rent or buy if you can a forced air heater if it gets as cold as it does here in fairbanks alaska and you park your vehicle outside cause your block heater may not be warm enough to keep you engine oil warm at times, the battery heater with keep your battery from freezing and killing it. i will be posting an image of the forced air heater to warm your block at these temps. in a few days so you know how to maximize the heat onto your engine block.

Do u have an engine block heater included w/ your weather kit? Using a block heater should solve the problem. If u don't have one, u can purchase an oil heater that u put in the oil dipstick tube, and plug in. Keeping the oil warm will be a big help in cranking the engine over on those cold days. If the explorer was an older vehicle, I would recommend having the starter checked out, as it is possible that it could be responsible for slow cranking, and difficulty starting. Are u using the proper oil weight? Oil that is too heavy will make starting difficult in extreme cold. Make sure u aren't due for a tune up, as everything must be working well to start in such extreme cold. What is the rating of the new battery (cold cranking amps)? Hope u bought a good quality heavy duty battery.

    Do u have the 6 or 8 cylinder engine? The 8 calls for 5w20 oil, the 6 5w30. And Ford Tech brings up a good point about connections, as that can cause the problem u describe.

Make sure you have good clean connections from battery to starter and ground. If all okay, you may want to have a starter draw test performed.

My ford focus will not start after replacing the ignition tumbler

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

Hood latch

Try spraying the latch mechanism with WD-40 or similar light oil and operating the release cable a number of times. Check the condition of the release cable if nothing happens. The latch itself may have a broken spring due to the low temps.

Replaced battery and starter. My 2004 ford explorer will not start. Auto zone checked battery it was bad and checked starter it was also bad. Both replace will not start

this is a stupid idea but one of my co-workers have a 98 explorer and she lost the chip in her key. after that it still wouldnt start turns out the anti-theft kicked in and they had to reset the fuel shut off switch. your battery replacement maybe did the same? not sure where your switch is but hers was up under her passenger side floor board up front somewhere around the kick panel it was a purdy red button
