Hello there I'm Scott,
Does it turn over ok when its cold or does she turn slow? Describe how it acts when cold and lets try to figure this out. Cold weather can bring out problems that warm weather doesn't affect. Fill me in here. Thanks.
Please be sure you are 100% satified with my answer before you hit accept!
Hmmmm, Well you are getting up there on miles and what you might be experiencing is a compression drop, which can cause a hard starting problem. It could be nothing other then that, but ya might try cleaning your mass flow sensor(you can get a cleaner at your parts store) and see what happens with that, while you are at your parts store you could have them run a test for codes and see if there is any stored in the computer pointing at something. Then if nothing comes up and if nothing I'd run a compression test to see where you are on compression. From what I've found that is a high compression engine and runs at about 195# XXXXX if it is considerably lower that is probably whats making it harder to start in the cold. I hope this info helps you out.
Well that it is very posible, but ya I don't know enough about this system to give you acurate infromation here. I'm going to opt out and see if I can find you a mazda expert ok. I wish ya lots of luck here. Hopefully an expert will be right with (if i can find one online) Thanks for using JA!
Sorry. So much info I forgot it wanst starting now - oops.
You can still test fuel pressure bleed own just by cranking the engine with the key. Or you can use a jumper wire (read paper clip) to jump the test terminals under the hood to run the pump. See the diagram below:
This connector is near the battery.
Let me know what you find or if you have any other questions.
Okay... will do. Ya know if this was an IH or John Deere I'd have the @@#$ thing fixed by now...
I'll get back to you after finding a fuel pressure gauge checking some of these things out...
Okay. So I pulled the vacuum line off the fuel regulator. too small to see inside but it smelled like fuel. Ran a qtip in it and that smelled like fuel, but not noticably wet. Put the vacuum line back on and the car started right up.
Just checking to see if that's significant at all. I still have to do the fuel gauge stuff - I just started with the easy check that I didn't have a 2 hour round trip for.
Haven't had time to pursue your suggestions. I don't have a garage I can work in and I leave for work at 6:15 and don't get home til 7 or 8 pm. Dark and cold before and after work. Also makes for a tired boy.
I'll get back after it this weekend.
Sorry for the delay. 2 blizzards, the holidays, and several other distractions later, here's what I figured out...
Checked out the fuel system - pressures, check valve, everything okay. I was referred to a guy by someone I work with and he said to replace the distributor. I did. It works.
Thanks anyway... and sorry for the delay.
