How easily does your FSJ start when cold?

[AwesomeJ10]

I've had lots of Jeeps over the years and they all have "methods" for making them start and run.

What are yours?

Be honest!

[AwesomeJ10]

I'll start out by describing my old J3000, which I sold to my neighbor.

It's absolutely amazing and will start and run (cold) without pressing the gas pedal even once. I've NEVER seen an old truck, FSJ, etc do that.

I converted all my FSJ's to TBI to eliminate this problem

Just two pumps of the gas pedal, and it starts immediately. IMHO carbs are just fine for the cold.

I push the pedal down once to set the choke (My weber requires that), and then turn the key. If I have driven it recently it will start in a second or two. If its beena while, then I have to pump gas back up to the carb so it takes a few seconds of spinning. My old Cherokee was the same way.

[HOOT]

When I was driving the J20 almost daily it would fire up instantly just turning the key. Now that it sits more it is a bear to start and currently it won't start at all. Getting ready to go make new steel gas lines and drop in the new battery to see if it will fire. Then I'll get it from being T Boned into my F350 and back up in the driveway, from there the carb gets pulled at rebuilt.

The J10 has never liked to start. Always a pump till you get tired then hope it fires up before you give up and hit it with a shot of ether.

I refrained from voting as I don't consider either of my Jeeps as runners right now.

Depends which one and how cold it is. One, needs 3 pumps, hold it down and pull the manual choke, but only in much lower than freezing temps. Most of the autochoke ones require 1 tap to set them. The MJ and Black Jack just need the key turned (Jeep EFI)

None of the above, flip the key on, 35-45*F and colder push the button, wait for the red light to shut off, and turn the key and it rolls over and fires right up . . . Well from 15*F and warmer about 5*F they start really hard below 0*F forget it. From 55*F and above just crank it over

I tap the gas once and click the starter and she's runnin. Hei did this, and I almost wish it would turn over a few times to avoid dry start. I solved that problem by stealing the pre oiler from my diesel truck.

[AMGeneral]

My Cam lopes sit in a trey of oil, My mechanical oil psi gauge jumps up to pressure as the engine rolls over and fires up with oil pressure built up

The diesels hold about 15psi for a while after its shut off too but it eventually bleeds off after a couple days, International Gas engines used to also have the anti-bleed back oil systems too

Shocked AMC never used such a system in there engines

I sit in the driver's seat and make motor sounds with my mouth. I didn't see that option.

[lindel]

Pump it 3 times on the first start of the day, generally don't have to again til the next morning. I don't have a choke on it at all, so takes a few minutes to warm to the point it idles happily.

[rstep]

With the new carb just a turn of the key and she fires up.

[MT1]

No choke, no cold weather, no problem.

[AMGeneral]

Well that is awesome ! Glad you got No choke, No cold weather, and No problems

Mine starts right up when cold, within one revolution with a pump of the gas. Hot however, is another story. If I restart within about 5 minutes it fires right up. Any longer than that and it spins, spins, spins. Then fires.

[AMGeneral]

Sounds like you need an accelerator pump ! Next time instead of letting it spin over, put it to the floor and crank it up see if starts any faster.

Carb is fresh, exhibits none of the accel pump symptoms. I will try opening the throttle to see if that helps. Its not really bad, I may have exaggerated a bit , it will spin 4-5 revs before firing and settling into a nice idle. Not a problem, just different from its cold starting manners.

[AMGeneral]

Oh ok its been a while since I have played with carb's The Generals have Isuzu diesels and the Comanche is EFI.

I read an article recently, can't remember where, but it suggested that many of today's problems associated with carbs (hard starts, empty float bowls, etc) can be attributed to the alcohol in the fuel. I'm not referring to the affect the alcohol has on the parts but the volatility of the blended fuel causes many problems. I will see if I can find it and post it up to share.

Howdy...

My ‘76 401 Wagoneer cold engine starts were from -20f degrees to 113f degrees, and from 500 to over 14,000 ft of altitude, and any weather. Hot Starts were another matter!!!!!
A . Rotate selector to a fuel tank (stupid) with fuel in it.
B. Put TH-400 in Park or neutral (with brakes set) and turn on the proper (one of 3) electric fuel pump.
C. When you hear the pump stop pumping depress throttle peddle and pull manual choke 7/8th open and release throttle peddle.
D. Turn on ignition with key.
E. Push starter button (on dash) until engine cranks and push choke cable back in!
F. If engine fails to rotate switch over to the other battery.
G. If engine fails to fire unplug and re-plug ignition module.
H. ... well it never failed... 'Cept for one bad starter.... #:-s

Have a cool one.. Don S..
