it often happens in the winter, naturally, the cold weather will have some effect on all the car's system, especially the battery and cooling system. _______________ Easy to get a MST-3
It is normal for batteries to lose a good deal of their power due to cold temperatures. If you want better starting power, try using a battery charger/maintainer overnight. It should charge at no more than 2 amps. The slow trickle charging overnight will charge and warm up the battery and allow it to develop full power for a cold morning start.
here are some signs of a bad fuel pressure regulator: the vehicle runs rough, the engine will not start(usually in morning) MANY TIMES ENGINE STARTS BUT STALLS SHORTLY AFTER STARTING. a bad regulator can result in fouled spark plus, and fuel milage will decrease noticeably. the only cure is to replace regulator. what makes it fail usually it gets a tear in the diafram and it cant maintain fuel pressure. hope this helps toolman,
usually its colder in the morning so it could be the battery doesnt have enough cold cranking amps or the battery is going bad. maybe. over heating could be a number of things make sure the fans go on half way up the gauge. but u should start by changing the thermostat its cheap,easy n should be changed yearly
replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump
It can be worn distributor cap/rotor or coolant temperature sensor.
To check it leave car outside, try to activate if it is not use the hair fan and worm up the distributor cap area http://www.autozone.com/Ntt,distributor%20cap/shopping/allResults.htm
If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor: http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c15280090338
and, if no help, spurk plug area.
Also good idea in cold weather use higher octane fuel or regular with octane booster or injectror cleaner added and ask the mechenic to put winter oil (less viscous) for winter time during oil change.
Good Luck
Replaced the coolant temp. sensor and it started up this morning and the temp. here was in the 30's. Thanks Johngee!!!!!
