hi guys,

Haveing some problems with the fuel delivery to my engine. Engine wasn't starting the other day, so after reading some threads about people who had the same problem i came to the conclusion that it is something to do with the fuel system, i therefore checked to see if any fuel came out of the fuel filter (filter was just replaced a month ago) when the engine was cranked...nothing. I have located the relay where the ECU is and the one in the boot, how exactly do i go about checking them to see if there the problem? Any other things i can do to check what it is that is wrong????

cheers.

take the fuel pump out which is under the floor on the right side of the boot.....

see if there is any voltage getting to it, and when you turn the ignition on you should hear it prime the lines and buzz away, if 1 there is no voltage then it might be a relay...

or the common cause is the fuel pump has died... there is voltage but no action....

Get a new pump if its the 2nd one :happy:

Ya get a new bigger better one!!!! I had this problem - my car was broke for days while I tried to figure out what was wrong. We pulled the pump and replaced with a 550. Now is great! :)

O, if you do get a bigger one don't forget an FPR or computer will be in order after a while.

      Have you done the Ignition Sync Wizard in the AEM software?

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
