over fuelling issue.

[Scottblue5]

Hi folks.
I was out in the car over the weekend without issue and today I went to start the car and it's massively overfuelling.
No setting have been changed and I have tried another msq and it's still a good 25% richer.
Could the problem be my fuel pressure regulator as iv checked the return line and all vacuum hoses and they are all fine.
The engine runs fine just mega rich, if there was a problem with the injectors the I'm sure it would be running like a burst arse?

I would check sensor readings and fuel pressure first.
