Trouble starting
#21
It feels very solid when I push down on the button, like it won’t move. Sticking up about a cm or two. Am I pushing the right one? Little black case with a black button on top located beside the passenger dash
if the fuel pump relay was blown then the pump wouldn’t be humming or vibrating though right?

forget the Haynes! Use the factory manuals.
my website is: jagupgrades.webstarts.com
when I put a link to it, it comes out as www.jagupgrades.webstarts.site
Don't know why.
just type jagupgrades.webstarts.com in your browser. Let me know if you can't connect.

I'm not clear where you are in the diagnostic process. Please clarify.
You said "So I went through the fuel pump circuit, all is fine." The fuel pump circuit includes the relay and the inertia switch.
If so, that leaves the fuel pump itself

for good used spare parts contact David at Everyday XJ
surely he can supply a relay and pump assuming they are bad.. If no luck with pump I have a used one that works but it is noisy.
did you go thru the No Start checklist?

I’m sorry I didn’t mean the whole circuit, just that the pump itself was vibrating while the engine was cranking so I assumed the whole circuit was fine because it was getting power
I’m not sure how to check the relay to see if it’s the problem or even where I’d get a replacement

If the pump vibrates while cranking the relay is working.
Whether or not he vibrating pump is actually pumping fuel is another matter. But let's not go there yet.
The fuel pump circuit has two operating modes; two "branches": starting and running
Since the pump vibrates when cranking the engine we know the starting branch of the circuit is OK. But, since the engine won't stay running, we have to look at the running branch of the circuit.
Remove the air cleaner cannister. This will expose the front of the Air Flow Meter. At the front of the Air Flow Meter you'll see a metal, spring loaded flap. Now, turn the key 'on' and then push the flap open with your fingers. You should hear the fuel pump run.
Post back with the results

If the fuel pump is operating (and we know you have a spark) then the problem might be with the power to the injectors. Next to the fuel pump relay is a diode pack and the 'main relay' for the injector system. I have had problems with poor contacts or wires breaking off from the connectors in this area before, resulting in no power to the injectors.
Check for 12V at one of the injector plugs. It should show 12V on both pins with the ignition turned on. If it is not present, check back to the main relay (Bown/Slate wire), and if that doesn't have 12V, check at the diode pack (white wire).

That is how I do it, because at times is difficult fore to name some of the parts/items and by so doing g learning becomes smoother.

Sorry I took so long to get back but I’ve been busy
i tried just about everything you all have said and that weirdly lead me to the fuel pump again... turns out the posts on the new one are actually marked incorrectly and it was flowing backwards.
she starts now but won’t rev higher than 1000 rpms
