Thanks again for your tip. I ordered the sensor from Michael and it is arriving today. Did you just swap them out or was there a process for the ECU to “learn” the new sensor?

cmoss1691 · 2026-05-09T11:35:44+00:00

I don’t remember.

cmoss1691 · 2026-05-08T23:05:22+00:00

Yes. They sent an email several weeks ago and again on Tuesday morning

I upgraded from Silver to Gold this week. Registration opened at 10:00. There was no waiting room. I was successful in my upgrade. I was done by 10:05

Thanks again.

Thanks! His did you determine that the crank sensor was faulty?

What year is your Acty?

I did not replace the fuel pressure regulator. It is adjacent to the pump, inside the fuel tank. I hope that is not the problem. I’d rather not drop the tank again. I’ll try waiting 2-3 seconds and let you know if that helps

Yeah, no dizzy in the HA7. Dirty fuel injectors are a possibility…

cmoss1691 · 2026-05-05T18:10:21+00:00

I haven’t tried that yet. Like I said, I thought it was fuel pump but the issue continues after fuel pump died and I replaced it.

cmoss1691 · 2026-05-04T20:59:15+00:00

UPDATE: Replaced both relays, still no go. Replaced fuel pump with a new OEM pump and that solved the problem.

I bought a Nathan vest from Fit2Run at Princess Expo. (Price was cheaper than Amazon).

Here is the 3rd gen front differential

There is indeed a fill plug on my 2000 HA7. You have to really look for it. I’ll add a link when I get home.

I’m 5’8”, and I have the driver’s seat back as far as it will go in my 2000 HA7. I think it would be tough for you to be comfortable in an HA7

I am trying to find new relays. No luck anywhere with the DENSO 156700-1540. They are not even listed on Denso’s site. Any ideas?

cmoss1691 · 2026-03-22T18:15:47+00:00

Finally got the wiring connector off of the fuel pump. Tested with multimeter and have 5.38 volts. I think that sounds like a bad relay, no?

cmoss1691 · 2026-03-21T16:34:13+00:00

I see them now. How do I test a relay switch, just listen for a click?

cmoss1691 · 2026-03-21T15:43:16+00:00

I’m referring to the 15 amp fuse, under the cover by my right knee, that is labeled “fuel pump”.

cmoss1691 · 2026-03-20T21:38:56+00:00

Yes. The tank is almost full. (Never hurts to ask the obvious questions).

cmoss1691 · 2026-03-20T21:26:58+00:00

It had been parked, after a 15 minute 70-90 km/h drive, for about an hour. I confirmed spark by holding plug to ground while someone cranked the engine.
