Tehnation Posted March 27, 2014 Share Posted March 27, 2014 So I had upgraded fuel pump to dw65c, and everything was working fine. Then it started having trouble starting when the gas was low, I figured I must have thrown off the float sensor, but now the problem is occurring with full tank of gas. Any ideas? I'm guessing fuel pressure regulator. The only thing I haven't replaced yet. Would a blown fpr prevent my car from priming and rough idling when it actually does fire up?

Tehnation Posted March 27, 2014 Author Share Posted March 27, 2014 I mean a replacement No one has it in stock. Part number 22670AA381 Link to comment Share on other sites More sharing options...
Tehnation Posted March 30, 2014 Author Share Posted March 30, 2014 Found that part replaced regulator fired right up. If anyone has starting issues or idle issues, make sure to check fuel pressure. Seems like mine was shot for a while now. I didn't get the entire assembly just the 80 dollar regulator part, takes about 30-60 minutes to change.
