SOURCE: truck after engine gets hot starts sputtering

You're getting a condition known as "vapor lock" or hydrostatic lock. This happens when you run your fule lines too close to a heat source (exhaust, engine, etc). You can solve it by re-routing it away from those heat sopurces...this should help.

SOURCE: 94 lumina will not start after getting warm. will

The check engine light should be on with the engine running. The coolant temperture senser may be open at some temps the fastest way to test this is to change the senser ( it's cheap and a high failure rate part all auto parts stores will haveplenty of this high failure part in stock and they fail many ways. If the car ever overheated it's damaged or truly bad. A very good one will optimize fuel mileage so if it's suspect change it anyway as money well spent a working but wrong senser can cost alot of gas on any fuel injection car or truck, You get what you pay for in temp sensers and the brand name ones are better. All of them are suspect to be bad even when new and ohm test at temperture charts are is repair manuels. Crank sensers and cam sensers also get hot and quit they cost more are harder to change and fail more on the 3.8 motor than the 3.1 or the 3.4. Igiton modules do this too but it sounds like its been doing this awhile and modules and crank sensers don't stay half bad very long. they stop altogrther. Temp sensers can stay bad and work wrong. If you can get a scanner hooks to the car on data stream the senser may show room temp when cold but as it heats up goes up then to -34 thats open the system doesn't know that to do as the air charge temp senser doesn't agree and the system fails to start and will check as flooded. Flooring the gas and hoding it there may start it anyway. The trottle position senser were to show open thats the clear flood mode and the injectors won't fire. Tps voltage should show .5 volt les than 1 volt at idel (it'll start) and 5 volts at full throttle or nearly. if it shows with a scanner of a voltmeter on the center wire 5 volts or 0 it won't start. Coolant senser fails more often and is cheaper

SOURCE: hard to start in hot weather

Start looking at temperature sensors and maybe even the thermostat.

SOURCE: Cold Starting

You have a cold start injector that is controled by coolant temp and more than likely the sensor, which is located center of intake, between #2 and 3 injector...it looks a bit like a reg. temp. sensor and will have either blue or black electrical harness connected to it. This sensor 'tells' the cold start sensor, a fifth injector for cold starting, when coolant is below a certain temp and gives extra gas. Try to find one at a junkyard, otherwise, www.getcoolparts.com about $80 new. Better yet, buy a Bentley manual and there's diagnostics using a multimeter on diagnosing specifically. I have an 88 but it is an N/A, not a turbo and is an 8v...if your's is a 16 valve, look for sensor in same spot but under fuel rail/injector area.

What would cause my car to not start up in bad weather and start up after a couple sunny days


Moisture in a wiring connector . When you turn the key to the start position , does the engine crank . or nothing . This would be a either a no- crank - no start or engine cranks but does not start an run .

I have a question. I have a Kia Rio 2008 and since a few months now, i'm experiencing problems with the ac of my car. My AC is only cooling when the car is not driving, or when the weather is not a hot...


The noise is probably the compressor. Maybe the belt could be loose or worn. You may be low on freon. Start with the easy one, check the belt, then freon. Good luck!

After driving into high water we took out the spark plugs and wires,cranked out the water,replaced the parts ,but now idle speed is much higher.what do you think?


if it starts fine and runs,best thing to do is let it dry itself out,it just may settle down,consider yourself VERY lucky if it does run.a nice sunny day(or two)with the hood up will help.

Difficult starting in warm weather


Check the vacuum hose attached to the fuel pressure regulator under the hood next to your intake pull it off and see if any fuel is present, if there is replace regulator.you may have to tap hose with your finger to get any fuel out or start vehicle run until hot then shut off and recheck if no fuel present in vacuum line let me know and we can try something else.
