major issues

[kanksca18det]

Well here it is. First of all where can I get a new ca18det wiring harness? The other issue is, Im having a problem, when I step on the throttle my car isnt reving up. Some times I keep tapping on it, then it will rev up. When I go to drive it sometimes its ok nd then sometimes I have problems. It bogs out, then when I tap the gas it rev higher. I duno what it is. I have the Ca with a t28, sr20 maf, at 10lbs, i put the walbro pump with nismo fpr.

If I was in south florida, I could probably help you! But I need you to read the new sticky up top and follow some of the instructions in there. You must provide more information than what you are providing because your original post confuses me as to what you're really requesting.

Ok, I have an S13 with a Ca18det, t28 off a S15, mbc at 10lbs, walbro 255, nismo fpr, Sr20 maf. Ok well when Im driving sometimes it fine, But most the time Ill hit the throttle and its starts to die out. Then some time when I do have it on the road, Ill be driving and Ill hit 4,500rpms nd its doesnt want to rev more, so I tap the gas nd then it will rev up. I duno its hard to explain. I duno it would be easier on the phone.

Sounds like fuel filter, or not enough fuel pressure. After replacing the pump and regulator, did you do a fuel pressure test?

Did you install the regulator the correct way around?

Could also be the ECU is in limp home mode. Have you looked at the diagnostic flashing lights on the ECU?

Also if you don't have a vaccuum line running to the fuel regulator, the fuel reg cannot raise the fuel pressure when under boost. The boost stops the injectors from working.

Yes I do have a vaccuum going to the regulator. I changed the filter when I did the pump. O, nd I did install the fpr the right way. What fuel pressure test could I do?

Can you use the SR20 MAFS w/o some sort of ECU correction? I would think that it would make the car run lean...
