Im thinking you may want to look into a possible prob. with your alternater..AnswerPersonally I've experienced this myself I'd say it was the advance not the alternator. On the distributor most often , you'll find either an electronic or vacumm advance . If it's a gas engine when it gets hot before it stalls if the engine starts to knock or sound like a diesel engine then it can be pretty safe to say it's an advance problem or if you don't have an electric distibutor see if the cap and the base are tight if one of those is loose then the timing for your spark would be off and as the vehicle gets hot the advance if working proparly would advance the timing out of sink beyond the reach of the spark inside the distibutor cap and Knock or diesel and eventually stall and not start until it cooled unless jump started in which case the extra juice gives bigger spark and extends its reach within the distibutor cap.
check the distibutor for tightness if its not then try starting your car and ever so slightly turn the distibutor until your engine sounds better its a quick fix and may take a couple of tries but it should help. if it is tight then look into getting an timing advance most part store can help explain the replacement (very easy and straight forward) or even help diagnose it but if your part store doesn't seem to help or don't really know much them selves find a new store too
Could be faulty ignition coils especially if engine starts when cold then stalls and will not start once warmed up.
If white smoke is coming out of the exhaust when the engine is warmed up , it sounds like engine coolant is getting into an engine cylinder
Check for vacuum leaks.
my suburban wont start
i have a 2000 dodge work van 318 engine when i start in the morning it stalls several times until it warms up then ok
The van runs well for about 6miles about 15mins. Once warmed up it splutters and stalls. I will wait for about 3 mins before the engine will re-start. The engine will run for a few more miles and will splutter and stall again.
There's a solinoid in the transmission.Suggest to check that first. Turn on interior lights. Start engine. If the lights go out when the engine stalls, you have a bad ignition switch.
If the engine runs well after it's warmed up, you just need to adjust the choke to make the engine start and run better when it's cold.
engine will idle high at start up same as a gas engine will. contrary to what most say, the newer diesels have same application on them as a choke. once engine has warmed up it will idle normally
Start it up again.
A car may start better in the afternoon, because the heat of the sun has warmed up the engine. Once a car has sat over night, it may be difficult to start in the morning because the engine is cold.
