car starts when warm, not cold. Above 40 degrees car starts fine below that nope, no way. Engine rolls, have spark, have 43psi fuel pressure.

New plugs, wires, battery.

Will coolant temp senor do this, no code.

Losing my mind....

 

ok it hits 43 lbs of fuel pressure then it lets off over a minute.but when the temp is above 40 or car is warm no drop off?

Fuel pressure regulator?
filter?

any Ideas?

 

how old is the filter? filter shoudl be replaced anyways if its old... have you taken it in anywhere?

 

this thing is a mess it is so hard to start, but once its warm its fine...

 

When it does not start, does the starter make any sounds?

 

Starts like always not a starter problem, this thing has 43lbs of fuel pressure, but it seems the injectors might not fire right away when cold.

 

I was working on a theory that perhaps the starter was going bad. When it's too cold out and you try to start the thing in the cold does it sound odd at all? I admit, I'm reaching as I'm really not sure what would be temp specific like this at present moment.

Something else to possibly consider is a fuel pump. I've read of some people having issues with their pumps in cold weather.

 

I am looking but she holds 43lbs of fuel pressure I am starting to think its electrical? Still testing
