Re: 1990 dodge spirit startig problems
If were having problems with starting in the morning
you might have gas draining back into the tank causing a hard start.
or if you look at the throttle body there is a tpsthrottlepotioncenser if this is not getting a signal this too will cause a hard to start,
Is there a check engine light?

It could be water frozen in your fuel system (fuel line, fuel filter, fuel pump or pickup or fuel rail). If you can get the car into a garage try letting it warm up, otherwise wait for a warmer day, to try starting it. If it is water in the fuel, you can add "dry gas" to your fuel which is an alcohol product designed to be an antifreeze and to absorb the water. However, if the water is already frozen in your system, this won't help without warming the car up first in some way. If you haven't changed your fuel filter in the last year, I would do that as well. Water can easily build up in a filter and freeze there in extremely cold weather. If this problem is water related, also fill the tank completely with a fresh quality gasoline, and add dry gas for the next several fill ups to help get any water in your fuel system out to keep it from happening again.
Sounds like the automatic choke control on the carburator is shot! It is stopping the proper flow of gas from getting to the engine...replace it! Also make sure you have recently replaced the fuel filter; moisture in the gas will stick to the filter and freeze up making it hard for gas to get through!
Start with the simple things first:
Make sure you have a clean air filter.
Change out your fuel filter.
Most of todays crappy gas is 10% alcohol and the weather is warming up.
Then if not:
Sensors and computer chip upgrades may be the issue but start simple. If you have a good reliable tune up guy take it to him and have him run the diagnostics. Any lights or codes come up??
check the glow plugs circuit to ensure that the pre-combustion chambers are being suficiently heated. also fuel cetane rating must be high enough for cold weather starting. diesel will gel when cold if the cetane rating is low non winter diesel that is. A good fuel stabilizer could help. hope this helps
you drove from a warm climate to a cold one in a short period of time, compared to climate change which is gradual usually. My guess is that the last time you gassed up the car it was still warm there. When you change temperature quickly like that, condensation forms, and you get moisture in the tank and the fuel filter. When you reached you destination, and **** the car off, it was cold, and somewhere in the gas line it froze. Try changing the fuel filter, and ad a can of heat. this should dry up the moisture, and solve your problem....
Well, could be many things, but first and easiest, check the dist. cap and rotor, and all the plug connections. Any moisture will freeze and short out the ignition system. Also change the fuel filter. If you get the slightest moisture in the fuel it will lock up the filter when the water freezes. Could be a relay, probably "engine relay" that sticks when it gets too cold.
