Hello I have a 1996 ford mustang gt 4.6 sohc. Sn95!! I drive the car in winter, ad this problem just came up, I drove my car parked it for the night, and in the morning went to start it, the motor would just sit there and crank over and wouldn't fire, I have spark my fuel pump humms everything seems to be working, but if you press on the fuel pressure valve no fuel squirts out?? I tarped my car up, and put a heater underneath it, this is -35•c over night, the car fired up no problems at all, if it is warm out say -20•c the car will start no problems, I can't figure it out, looking all over online I'm Guna change the fuel filter yes, but hear is my main question. The coolant sensor???? Will that being so cold out make it malfunction and not work, then when it's warm it works?? Please help

 

I feel like I read this already.

 

Right?! Just a few times....kind of annoying seeing the same post on 15 different threads...

 

I would check your antifreeze strength and see what temp your antifreeze is mixed at. If it's not a close enough to 50/50 it might be starting to freeze up or something. Otherwise I'm not sure what to tell you, my 04 has been starting only a little slow here and it's been in the negatives a lot lately. Never really heard of anyone having a coolant temp sensor prevent the car from starting...so idk good luck. Hopefully someone has some ideas for ya

 

normally a coolant temp sensor will cause it to just run in rich start mode when it goes out. never really heard of it causing it not to start when cold but i guess it could.

 

Sorry about the million posts lol I'll check the antifreeze, it's like i put the car in the garage, I will start, leave it outside won't start, I think recently I put some antifreeze in that was a bit Die-looted from sitting around for. While

 

My car turns over but won't get fuel, my pumps working

 

gotta be filter or bad pump or maybe the regulator is sticking open. cts has nothing to do with fuel pressure. take out the fuel filter and put a fuel pressure gauge on the line there.

 

In the future please refrain from posting multiple threads/post on the same topic across multiple sections.

 

Thanks for the fast help, I'll try that and for next time I know to make one thread, I was just goin nuts trying to figure this car out, without it I'm stuck at home lmao
