Hello. I am new to this and thought i would give it a try. my car takes awhile to start i'm thinking it could be a few things. the fuel pump ( which i don't think because i can hear i come on when i turn the key to the acc) or could it be my fuel regulator? is there any ideas on how to check where i problem might be coming from? any help will be great.
Thanks

if you have or can borrow a pressure tester it should be 50ish when it primes and stay there for a long time, if not its likely the fpr.

what knid of car and year, mileage?

Try pulling the vacuum line off the FPR and smell it. If you smell gas, then it'* bad. Also, just because you can hear the fuel pump, does not mean it'* working right. You need the correct pressure, 46-50 is what your looking for KOEO.

Just got it tested and it looks like the FPR was bad. the fuel pump was pumping 50-53 and then slowly the pressure drops. replaced the FPR and all signs are ok. Thanks alot guys this really helped.
