SY wont start cold

[Nasariobv]

Ok so ive been having cold start problems, so i cahged the rotor,cap, and coil, still the sy struggles to startup at cold, it takes a good minute of craking before it starts up, and it runs good and it will start up fine after a warm up, but i let it sit and it does it again????? anybody have ideas as what i sould check next???/

Well, mornings around here are at about 35* right now, so cold starting has become an issue. I dont have any real problems, Its just not very quick to start, usually starts up perfectly on the 3rd crank, I only crank for about 1.5 seconds at a time. My Ty is my daily driver so Ive figured out how to start it pretty well in the last few weeks

What I try to do is make sure the fuel system is good and primed before I crank it . It usually gets easier to start it later in the winter, almost like it gets used to starting cold.

As far as the starting problems, Id check the vac lines for sure...a vac leak will make cold start-ups a beyatch.

Xylene will also make it for a hard cold weather start.

Check fuel pressure. Symptoms are consistent with failed check valve in pump, allows system pressure to bleed off, causing 1st start to be hard. Another possibility is bad engine coolant temp sender, engine does not 'know' it's cold out and fails to enriched mixture properly. a scan tool will tell you what temp the engine 'thinks' it is at start up.

ok

ok

ok that brings up something else, i have tried chaging the coolant temp sensor and i get a check engine light, but i put back the old one and it goes away? I know that im not getting accurate temp readings from the temp gauge, and thats y have tried changing the sensor before....

Seen that before, but on an Astro van. It that case, it was an intermittent open in the wiring. If the "check engine" really tracks with the sensor (swapped it more than one and the results were the same?) then it sounds like you bought a bad sensor. However, if it is really just a wiring problem, and changing the sensor is screwing around with the wiring, then I would not expect it to be repeatable.
