And lastly, I've ordered a fluid filled pressure gauge to test my fuel pressure before finally deciding to replace my pump.

What pressure readings should I expect at what rev range for the pump to be working effectively.
Cheers.
Around 40 psi at idle but that won't say much. The real stress test is under WOT/high rpm. It should remain constantly at around 60 psi, certainly above 40.
Fuel-safe relay page 19-137 in the SM. Relais are quite cheap.
EDIT: with the fuel pressure gauge mounted you could go do a dyno of the car and monitor the fuel pressure. It's a little bit harder on the road to detect a fuel pressure drop as you didn't noticed it in 1st or 2nd but in 3rd (on UK roads? :)).
EDIT: For some reason I only saw page 1 on my cellphone and could not swich to page 2,3 and 4. I see you solved the problem. Good. But below was my suggestion, more in the electronical area.Quote:

I had similar issue this year with my stock engine. The revs bounced up and down while i still was on wot. And during shifting the revs gone crazy...up and down. After cooling down it was okay for 2 more laps, then the same again.
A guy with his race civic told me he had exact same issue years ago and it was the knock sensors cutting down power and revs gone crazy.... So i putted in heat range 7 ngk plugs.
We also changed the ecu and ignitor module and one heat range colder spark plug. All problems gone. :)
Whats wired is that with the exact same engine, ecu, ignitor and heat range 6 plugs i drove 3 times on track before in even hotter conditions. ...
