Right both my zed's have them, admittedly they are different brands but I'm slightly confused...

 

Looking into why the swb take a few turns to start, and noticed that with the ignition on there is no reading on the afpr gauge? But on the na there is, and it take a fair few minutes to set back to 0 after the ignition goes off...

 

On trying to start the swb there was a reading after I got it started, but it went very quickly after I set it off.

 

Which is normal? As I'm thinking the swb may have a leak somewhere although can't see or hear anything obvious...

Do either have a pressure gauge on the AFPR? I know it's a little different but my old car had a combined AFPR and fuel filter, you had to let the pump prime etc before you could crank it over or it wouldn't start, there were no non returns etc and it was a carb'd affair. It also had a pressure gauge so you could set it up, IF it's correct that the system should remain pressurised when off, which I believe it is then the gauge pressure shouldn't drop unless there is an issue, I do have a fuel pressure tester which didn't cost me very much I'd offer for you to borrow it if you needed it but I'm sure you will blag one from your work. Hopefully someone with more knowledge will be able to confirm what's normal.

Swapped them, checked all the lines, initially made no difference to either, bother apfr behaved the same on either zed,

 

But now the swb won't turn over....

 

Plugged the r-vit in, 2 error codes neither 02 sensor connected... Why???

 

Then check parameters battery voltage dropping to 11.6v so I guess the battery's dropped to the point the immobiliser has kicked in.

 

I'm assuming low battery could be the cause of the poor starting too.

 

Will pick a new battery at work, and bring consult home tomorrow...

 

Why did I buy another zed again???

So the pump isn't priming with ignition. If you can't hear it prime, and the gauge is reading zero, then there's no fuel pressure in the lines. If it initially primes on cranking, it will indeed take a few turns to fire.

 

Disconnected O2 sensors will have nothing to do with starting issues. They will have been disconnected by someone because they were believed not to be working.

It's the gauge on the swb's afpr it doesn't work properly, on the na it still started straight away even though it said the pressure had gone... And the good afpr from the na is showing a solid pressure on the swb,

 

Or so no O2 sensors isn't a big deal, fair enough, just got to hope it's my battery at fault now...

Nope, forgot to bring the jump pack home, the immobiliser on the na doesn't like having no battery, last time it was disconnected it took ages to get it to start again, and I can't remember how...

 

Thought about jumping the swb with the na but was getting late and my neighbours have small kids so I don't like playing with the noisy zed's too late if I can avoid it.

Not the battery... Tried it at lunch, can hear the solenoid moving but no crank, so assuming the stater is dead,

 

Wish it was at work would have been easier there.

It lives..... Thanks markderby for getting me the starter so fast,

 

Relieved was worried... Thinking what have I bought...

 

Slightly pissed off it lasted less then a week without incident, but starts straight away now, and one quick drive and I'm happy again...
