JA: What is the model/year of your Honda?
Customer: 2003 CRV
JA: Are you fixing your CR-V yourself? What have you tried so far?
Customer: yes, fixing self. Was checking info first. Was wondering if the fuel filter / pump is having a problem.
JA: Has the vehicle turned into a gas hog? And how does it start -- same as usual?
Customer: This is a friends car. She does not track mileage. starts as normal
JA: Anything else you want the mechanic to know before I connect you?
Customer: No.

Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

The fuel pressure or volume through the pump can be low, but also a plugged exhaust system will also cause a loss of power too. A bit of diagnostics is in order now with a fuel pressure tester and a vacuum pump. both of these tools can be loaned to you at your local parts store.

Please understand that I don't know your skill level or tools
you have to assist us. Also understand that I can't see, smell,
hear, or touch the vehicle either, so your patience is
appreciated. JA is a great Q/A site, but it does not replace a
repair shop. So please don’t shoot the messenger if I have to
deliver bad news:)
If you are satisfied with my answer, I would greatly
appreciate a 5 star rating now before you leave the site and I
will still assist you after you have rated me too if another
question pops up. I don’t get credit for helping you until
you rate me

Thanks, Ron

Okay, will rate. What pressure should this vehice have for the fuel pump?

48-55 psi is normal and for the volume, it should fill a pint container in 30 seconds.

Thanks again Ron

Hi, Ron, I'm writing you to let you know how it all turned out -- sorry my response is so delayed as we had company in from out of state for the last week. (This was for a 2002 Honda CRV where the motor was cutting out).
Well, as expected, the fuel pump tested out-of-spec (but not significantly so) and the strainer was noticeably blocked with debris -- mainly metal shavings. I installed a new pump in the assembly and replaced the strainer and the vehicle operated better, but the repair did not solve the problem of the motor cutting out! For grins I looked at the spark plugs and they were in bad shape -- they had never been replaced and the CRV had 158k miles on it. I did not expect that this would solve the problem (and it did not) but it did improve performance until the same issue kicked in. As it turns out, the variable valve timing solenoid was not operating properly and when the motor went above 2,500 RPMs (after warming up) and the timing was supposed to change, it would not / could not. The screen inside the solenoid was plugged. In this case, cleaning the clogged screen did not solve the problem so the entire unit was replaced. According to the owner (sister-in-law), the CRV has been working perfectly since then. I appreciate your help in getting me off to a start on the repair!

Hi Brian,

Thanks for that report, I always appreciate information like that.

Thanks again, Ron
