Won't cold start

I'm outside at work. Defender 90 1994 cranks very strong after fuel relay and fuel pump sound comes on but after that it only cranks and sputters but won't turn over. Thoughts?

Tried repeatedly and also with gas pedal down a bit but nothing. Car is near half full with gas but sounds as if it is fuel starved.

Wet weather out? Long time since new plugs & wires? If you have an auto parts or maybe a hardware store handy, dielectric grease in the spark plug boots might be your fix...

Do you have carb cleaner? May be worth a shot to remove and clean (spray) the IACV behind the plenum.

Not wet but EXTREMELY cold. Was 7 degrees this morning and when I left to start it to come home was about 20 degrees. Spark plugs, plug wiring/distributor all new within past 12-14 months.

I don't have carb cleaner on me but I just got home so will bring some to work tomorrow when I'm back at the office with my other vehicle. I did just recently (past 2 months) change the IACV out for a new one (non OEM). Replacing it appeared to have solved a long standing intermittent issue I was having with raw fuel being dumped into the Cats which always occurred following a very high idle. But that is another story and looks to be consistently solved with the IACV.

Back to your suggestion. When you say spray it I assume you mean take it out (unscrew the IACV) and spray into where it goes into the plenum? Or do you mean spray the innards of the IACV itself?

Spray the IACV piece that is in your hand after you unscrew it.

Long shot but I had a Chevy truck that did this one winter.

Filled up my gas tank and the next day the truck wouldn't start.

Ended up getting it towed to the shop, shop drained the tank and the next morning half of my gasoline was frozen... Aka half the tank of gas I bought was water. Might dump some dry gas in there and/or top it off with some fresh fuel and see if she'll start

Okay great thank you. I will do that tomorrow when I'm back at the vehicle. Appreciate the responses from everyone. I can't help but feel this extreme cold we had today contributed to this but I guess that doesn't explain why it started up so well this morning (although it was in my non heated garage this morning but today sat out for about 9 hours in real cold weather).

Thanks again - Will

P.S. I should have added from the beginning of the thread that when it cranks strong but doesn't run the appropriate dash lights go on, including check engine light, for the duration they normally do (and then check engine goes out) all as if it is a normal start. So I am thinking this is not an ECU related issue. Not sure if that line of thinking is correct but that is my limited knowledge perspective.

You know you might be on to something with that as well. I hadn't put dry gas in (but usually do) for many months. Thank you won't hurt to pick some up in the morning and dump it in (gas and dry gas).

First really cold morning this winter?
Check your coolant temp sensor (the one that goes to the ECU).

UPDATE: I came to work this morning armed with a few things based on your feedback but first tried to start the car again and it started a little rough but did start and ran fine. I kept it running for abut 30 mins and put in some dry gas.

Could have been any of the things suggested here but really felt like it was starved of fuel as if there may have been a freeze in the line.

It warmed up overnight and is much warmer today. Gong to be around 40.

Thanks
Will

Does "dry gas" work for diesels as well?

--Trying to sort out a similar no-reason for not starting issue.

Maybe Power Service Red/911 bottle?

I'm not sure I have no experience with diesel.

Similar thing suffered here for months until weather warmed up. Haven't had a chance to get out in it for a couple of weeks. Hopefully its not happeneing again.
My next stop is to question the actual capacity of the battery. Its a cheapo generic job. Wondering if its undersized in cold weather.

Water in a diesel is bad juju. Very bad for injectors etc. If you remove the drain from your filter and see any water you need a new filter @ a min. I typically have to change filter 2-3 times in order to clear a bad tank of fuel through.

You posted that you changed out the plugs, wires, & "distributor" a year ago & that the new IACV was non-oem...

By "distributor", I would assume that you either meant "cap & rotor" or that the cap & rotor were changed out at that time? If so, was the new cap & rotor also non-oem?

IACV has absolutely zero to do with the truck starting and idling. What it does is open and close depending on whether the truck is accelerating or decelerating to add bypass air to the engine so that it doesn't stall on decel.
The only reason for a no start when it cranks and you have spark is no fuel. I'd wager that you had enough moisture in the fuel system to stopper the fuel flow when it froze.
