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

If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor:

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

I have a 1998 chevy 1500 with a 4.3 liter engine,after it sits overnight it takes a while to start. After it is warm it starts fine and runs good,it happens after its cooled down


I would start by checking fuel pressure via the schrader valve on the fuel line (near the rear of the intake manifold). The vortec engines needed considerably higher fuel pressure than most to start cold, and it is quite common for a weak fuel pump to cause a cold only no start condition with that engine. You should see around 50-60 psi with the key on / engine off for about 3 seconds. Also, if the pressure drops very quickly after a few seconds, the fuel pressure regulator could be to blame.

98 astro awd doesnt like to start in real cold weather (-18C) otherwise runs fine


I have a 98 and we just had a cold snap where it was super cold and I didn't start it for about a week. I had just got a new battery because mine tested out bad. Everything was good but now it doesn't want to get fuel. Cleaned all battery and relay connections and it's turning over great and fires with starting fluid but won't start. Guy at Napa said the fuel pump on these are known to not work well in the cold and suggested to warm the tank. I'm parked outside and can't move it to get it inside somewhere. Anyone know of good solution to this fuel pump not working in cold temps issue?

2000 Blazer Cranks, Won't Start


First of all, a diagnostic wont tell them that there is arcing involved. I am thinking it is your crank sensor. It expands and retracts in different weather situations.It should make contact in all weather situations.

Just got an 1998 Isuzu Wizard (diesel), some times


It sounds like the fuel is gelled, is it cold where you are and what are running for fuel? If your in freezing weather you should be running blended fuel, straight No.2 will gel at about 25 degrees (F). Take a hair dryer or heat gun and warm the fuel filter up. Or if you can get in warm garage and get it started thin the diesel with kerosene, about 2 gallons to 20 gallons of diesel. Then drive it for at least five miles so the kerosene gets circulated through the system. I've used gasoline to do this too, but only use about 1 gallon to 20 gallons of diesel.

1997 gmc sierra pu.5.7L won't start in cooler weather when left outside or sits idle for a couple of days. The fuel pressure reg. has been changed with no apparent change. If I warm-up the fuel lines near...


you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

Transmission slow to go into first gear unless auto is warmed up


change fluid & filter. no dipstick, sealed tranny. can remove both pans from underneath to access filter.

It is a GM 4L30E trans. used on Isuzu Rodeo and Cadillac Catera. BMW, in their inifinite wisdom, markets it as lifetime fluid. The second biggest bunch of **** advertising that ever was. Heat and friction will wear out ANY fluid!

BTW, it will delay shifting into highest gear when cold. this is normal

Hard starting after sitting awhile


My 98 Jimmy runs on synthetic oil and starts well after sitting in cold weather. If the weather is the problem, try checking that. If it is warm... sorry no ideas.
