93 Grand Cherokee 4.0 trouble starting in cold weather

Code 22 Coolant sensor signal out of range - May have been disconnected to set timing

Code 24 Throttle position sensor over 4.96V

Get rid this vehicle to some pond and buy a new one.

Might be you ecu is going bad. Does the check engine light illuminate on the dash, right before you try to start it, the times when it doesn't want to start? If the light does not illuminate on the dash, then the ecu is the problem and needs repair or replacement. Basically, that check engine light has to light up on the dash, before the jeep will start.

Have you checked the crank sensor? Any trouble codes stored in the computer when it shuts off and won't restart?

get a couple bottles of gas line antifreeze .. if you don't already use it and add it to the gas.

P.S. in minus 40 i don't even get out of bed... minus 23 here last nite... isn't winter grand

The correct spark plugs are very important. Glad to hear you got it fixed good.

There is a sensor on the top of the transmission housing that if it goes bad can give you these sypmtons. It's called the crank sensor.

Could be a sensor.I'm thinking more along the lines of a fuel pump or fuel filter.If the fuel pump is going bad..similar symptoms.Would be advisable to install a pressure gauge at the engine,and check fuel pressure when it's acting up.
