Re: '05 Jimmy Long Crank but Won't Start Cold
Check that year and model and engine size.
Let half of what people tell you go in one ear and out the other.
4.3 engine you need 65 lbs of pressure for injectors to squirt on a cold start.
60 is 5 lbs low specs is 60/66.
Make sure engine is cranking good.
Check for good hot blue spark to more than one spark plug.
Is security light going out key on?
How many mile on it and last tune up?
As a start aid and for checking for fuel delivery problem spray some carb cleaner into the intake and see if it will fire on it.
But never use starting fluid.
Let us know about spark and security light and engine turning over and if caarb cleaner into intake helps.
