My 88 dodge aries floods out it seems when the outside temp falls below 30. it will run off of starting fluid but then dies. I checked mechanical and ignition timing, both were perfect.

Check that the temp sending unit/sensor is working properly. It could be that it has the computer holding it in cold start mode and flooding the engine. Like the choke is staying closed you might say.

lots of guesses. sure.. common here.
first would be a real tuneup , using the 60,000 mile list. for sure.
filters and spark parts. (my guess is you did)
1994 is a great year, all 93+ jeeps are good from 93 to now.
I presume this is USA car, and you scan it and there are no
DTC errors.????
seems its flooding ,
if 5% throttle makes it start, that is lack of air or flooding
if wont start and the super secret WOT crankings clear flood , then was flooded, Wide open throttle cranking , cuts all fuel (the secret)
so is , IAC/ISC stuck closed, chean it yet.
or injector leaks (pass the injector leak down test ,does it?0

got 500k miles o jeeps from 88 to 99+
and the ISC stick on them all.

the ISC is the electric, ldle speed control valve.
if it sticks closed, you cant get full air supply to start.
had to clean mine every 10 to 20k, miles.
until i found the magic, spray that cured that.
"klondike gun lube spray": looks like teflon after it dries.

that run rough started is called misfire.
and is flooding, (if injector are not leaking) its air supply wrong.
one more thing,
the ECT must read 30F when parked overnight, and was 30f.
see? a cold engine will be near ambient air, first thing, in the morning.

running old fueL:?
running summer fuel from last August?
the ECT sensor causes injections to match true temps.
make sure it reads right for all bets off.

clean ISC first. not shot gun parts
for that cash you could have got a nice scan tool.
like this.

the prefect tool for 93-95 jeeps. does OBD1 on JEEPS !!!!

Kinked brake line or other obstruction or a frozen wheel cylinder.

Replace the battery

maybe your battery itself ALSO needs to be changed...

a lot of auto parts stores will check your battery for you, under a load, to see if it is DONE.

if youve run it done many many times, or its just old..(5 years give or take)..its probably DONE

hope this helps.

let me know

check your fuel presher

I would check for a bad coolant temperature sensor, of a bad ambient air temp. sensor. You can check these with a good voltmeter, but a scanner would make things much easier. With the scanner, you can se what the computer thinks these sensors are telling it. If it's 20 outside and one of the sensors reads something like -10, there's the problem, but a five degree variation is not enough to make a difference.

check your timing!

i have an 88 dodge shadow turbo with a five speed. the car will fall on its face at 5500rpm coming out of first gear. and its rpm range gets lover with each gear. the fuel pressure rises when it fall on its face. the car never dies just falls then picks back up and will fall again unless you keep it under the that rpm. then it is fine. what could be the problem?

Hello doncoth...very low mileage for an 88 aries and i doubt that anything serious is going on.
In 88 these engines were carbureted, not fuel injected & majority of the stalling problems were fuel system related on these cars,
like a broken or split vacuum hoses allowing air to be sucked into the intake manifold. Unmetered air changes the fuel mixture, and can cause a stalling problem..
Since the check engine light is coming on we need to find out what the trouble codes are.
To get the codes, put the key in the ignition and turn the key to the "run" position until all the dash lights come on (DO NOT START) Have your paper and pen ready to take notes.
Turn key back "off",then to "run" again,"off" again and then back to "run " and leave it there.....The check engine light will begin flashing....It will flash a 2 digit code....For instance,2 blinks followed by a pause,then 1 more blink would be code "21"....The last code displayed will be 55 (test is over) From that information we can determine the cause of the condition. The codes can be read here>>>> http://www.allpar.com/fix/codes/index.html the list is at the bottom of the page. Let me know what you find. I'll be glad to help you.
Good luck and i hope this helps.
