You could replace it to cross it off the list. They are not expensive.
Or you could swap it out with another relay with the same configuration.
A mechanic would check the terminals when the truck will not start to see what is hot or not.

You could have a bad cold start valve, go to an auto parts store and buy the cold start valve and replace it. you will see it on the intake manifold also pull off the air cleaner or hose and get a can of berry mans carb cleaner and clean the throttle plate inside and out then lube the throttle cables with Wd 40 then try it, if it starts your set, if not try pushing the throttle all the way to the floor and crank for 15 seconds then wait one minute then slightly press the gas pedal and try starting again this is how you clear flooded engine. If it starts you know that the throttle plate or cable froze shut and would not allow air into the engine causing it to flood. also check that the O-ring is not missing on the distributor cap which would allow condensation to form inside the cap shorting out the plugs and allowing it not to run. if it does it again pull the cap and look inside the cap if you see moisture then you need to replace the cap and rotor and O-ring.

It sounds like it could be the transfer pump. Turn the key on and then crank the engine for about 1 second but leave the key in the run position and listen for the transfer pump to run. It should run for about 15 seconds after you stop cranking. If not, then you will need to replace the transfer pump with a in-the-tank conversion kit if your is mounted on the side of the engine block below the fuel filter housing. If you already have the in-the-tank pump then it might be siezed or the "sock" might be plugged up with alge or other contaminants. I usually lift the bed rather than removing the tank to replace the fuel module. If the check engine light is on you might want to have it scanned for codes to make sure since the modules can be spendy.

Hi there my mazda etude 160i wont start at normal operating temp must leave for few minutes then will start again


When you shut off a fully warmed up engine, the temp rises as all water circulation has stopped. This extra high temp can cause electronic parts to fail which then work again as they cool. Somewhat rare, but possible coil/module or crank/cam sensor issue. Also may have leaky injectors which bleed down when you stop and flood the engine. Sitting lets excess fuel evap and then will start again. Just my thoughts.

Sounds like EGR(Exhaust Gas Recirculation) issues. As this is a second-generation of OBD(On Board Diagnostics), it will need to be thoroughly inspected by somebody with a bi-directional scan tool.

Engine cuts off when it gets warm have replaced fuel filter


You'll need to figure out if you are loosing spark or fuel pressure when it stops running.
I would say it is something electrical, could be anything from the ignition module to a relay.

2002 Chevy Impala wont start after letting sit after it warms up


Almost sound's like vapor lock , the fuel boils in the fuel injector rail , turns to vapor ! That was a common problem with carburetors , letting the vehicle hot soak after shutting down the vehicle an letting it sit for 10- 15 mins. The fuel would boil away ! Are the cooling fans working ? After turning off a hot engine the cooling fans can run on without the key being on , do you hear fans run ? What engine does your impala have ? 3.4 or 3.8 L . Has the check engine light come on ? The fuel pressure regulator could be leaking fuel . Pull the vacuum hose off the regulator after shut off the vehicle , is there fuel coming out of the regulator ? Dribbling out the end of the hose ? This could be bleeding the fuel from the fuel rail ! Good luck , hope i've given you something's to check that you haven't already .

My Saturn ion won't start in cold weather. sfter waiting 10 mins it starts with no problem


sounds like a plugged fuel filter,,,changed it lately?? what might be occurring is,,after turning the engine over for a few minutes,,it just cant get the fuel,,,then after sitting the fuel slowly goes threw the filter,, and you get enough for the engine to start,,,clean filters are a must,,,give this some thought,,,their about 10 bucks if you change it yourself.
