It seems you have a bad battery or starter. If the engine does not turn freely. Check both. Check the battery first and make sure it is good and charged. Also clean the battery cables of any buildup. you can use baking soda and water to remove the acid and a small wirebrush to clean the cable and post (if any). to check the starter, make sure you have a good battery.And crank the engine. If it is still slow and sluggish with a good battery you may have a bad starter. if you want to check the starter you have to remove it and get a pair of jumper cables. connect the negative cable to the starter housing. Then hit the bolt where the positive connects to the starter. be careful because if it's good, it is going to jump a bit. It should turn smoothly and freely. if it does not. the starter is bad. If it still fails to start, make sure the spark plugs have spark in them. remove one and ground it to a good groung. it shold have a good blue spark. If not your coil is nor delivering. from there you will have to troubleshoot from the coil.

Did you try giving it a good tune up?

If it has been more than a year since you have given it a tune up, plugs and wires, this is more than likely your problem, with a truck of this age, they tend to gunk the plugs up....

    The temperature censer tells the computer engine temperature hot or cold.. the computer in turn enriches or leans fuel mixtures.. Lean when warm, enrich when cold. i have seen this censer go bad and tell the computer that engine is warm when in turn engine is cold. so engine wont start because computer has fuel turned down just barely not start but just wont.. change temperature censer not temperature sender

First thing to try would be different fuel. Use a fuel stabilizer and fill with good gas. see if that helps. Also, check the fuel pressure.

Suzuki sidekick jx runs good when cold after it warms up it revs up & down


it is your air to fuel mixture causing that problem.
When car is cold choke is out and more fuel is given to allwo it to run.
When car warms up fuel returns to a normal level and the problem starts.
If its a carb version then they will need ballancing.
Injection model will need tuning

1977 ford bronco wont start just clicks. have replaced starter,celinoid


If you are only getting clicks then the problem could be one of a few things. check your grounds for corrosion, breaks, and tightness against the frame/ motor. If that checks out, then follow your positive leads and insure that they are all tight. last but not least check to insure your battery is strong enough. you could have a dead cell in your battery, and that would cause you to not get enough juice to turn the engine over.
