Hard Cold Start
I have a 01 that requires excessive crank time to start, 3 to 4 seconds, when cold. It starts immediately when warm. Ideas?
I just bought this vehicle. It has 85000 miles. |
you posted this in the wrong section my friend. this it the website help section, as in help with the website itself.
to answer your question a full tune up would probably solve it. fuel filter, plugs, wires, cap, & rotor. Probably wouldnt hurt to dump a bottle of STP fuel system cleaner in the tank either. |

Yep, sounds like dirty injectors to me. |
Possible dirty fuel filter or pump is bleeding down when parked for a long time.

yeah, i forgot about drain back. im not sure where the fuel pressure regulator is either never had an issue with them on blazers before.
if it starts fine in warm weather i doubt its having a drain back issue. but you never know, it could just be letting a couple lbs of pressure drain back leaving enough fuel for a warm start. only way to know is to check the fuel pressure. |
What happens if you prime the fuel system first. Turn the key on and wait for the pump to shut off (5-10 seconds), then turn it back off. Do this at least twice before attempting to start it.
That will tell you if the problem is with the fuel pressure or not. |
