So the car had what seemed like a misfire to me ,
Was wanting to uprate the coilpacks anyways so fitted new plugs and updarated coilpacks.

This did not solve the problem .

So I fitted a new Z32 afm ,
Car then decided it didn't want to start and the fuel pump wasn't priming ,

Fuel injector fuse was blown , swapped it out and now fuel pump primes but still not starting ,

It cranks over but doesn't start ?
Engine management light has also just come on since changing the fuse ..

Any ideas ? Something I'm missing ?

What management have you got for the Z32 AFM. You can't just fit one as the readings will go to **** for the standard ecu :)

It was already running on the standard ECU with a Z32 , all I did was try a new one as I thought it was broken .

Ok, if it was running before okay it won't be the problem. The ecu must have been mapped by someone like Horsham

What has been changed or done to the car before the running issue started? Even the smallest thing. What fuel you running?

Take the pipe off the fuel delivery pipe, put it into a large bottle and crank it. See if you are getting fuel supply.

So you replaced the z32 and then the fuel pump fuse blew on its own? Did you short any wires or did you disconnect the battery before changing the z32?

Checked the fault codes with the paper clip trick,
Came up with AFM/MAF fault which cleared.

Now the fault seems to be actually with the spark,
Got some time today to have a proper look. Going to check the plugs are sparking . If not then I'll swap them back to standard.

Fuel pump is def working .

Battery was disconnected before doing any work 🏻

This is why I stay away from all wiring usually

Yeah and yeah ! And I found a brand new Z32 + plug in my attic earlier which I didn't know I had !!

So early I did some more digging and there is 100% no spark ?
Maybe a blown fuse somewhere I'm not seeing?
Could it be an ECU problem ?

Maybe your crank angle sensor?
Are you getting fuel on your spark plugs when cranking or are they dry?

Coilpack loom earth still connected on the back of the head?
I'm thinking you might have accidental ripped it out when messing with the coilpacks, won't start if that's not connected.
