Car Wont Start - Tried All The Obvious Stuff

I haven’t been able to start the car for a couple of weeks now and I cant figure out why. Two things I have done that might have affected this 1) I removed the resonator from the intake and maybe disturbed something 2) I let rain get in the engine bay (yes I know Im an idiot already!)
 
I have checked the following:
 
- I checked all the vacuum hoses, connectors etc and seem to be intact. On cranking it is totally dead, doesnt cough or splutter at all.
 
- It has spark and will splutter a bit with' start you b*stard', but otherwise it wont give any sign of life at all besides cranking.
 
- I bridged Fp and +B on the diagnostic port, cant hear fuel running through the rail or the fuel pump running in the fuel tank.
 
- I have powered the fuel pump via the connector and can definitely hear it running in the tank.
 
- I have checked all the relays and they seem to be functioning properly.
 
- No fault codes via the check engine light
 
So it seems there is no power getting to the pump. Im pretty sure though that I cant hear fuel through the rail either when I power the pump, but it’s a bit hard when my wife is nagging in my ear while I ask her to help me with this stuff. I could replace the fuel filter and do all the tests in the manual but before I do I think I need to focus on the issue with the pump.
 
Any suggestions (besides getting rid of the nagging wife)?

have you tried to start the engine with the fuel pump FP bridged to B+ in the diagnostic port?
 
as you say when bridged you can hear the pump run. so try cranking it. if it does start then it definitely is a power issue with the FP control circuit. if it doesn't still then its something else.
 

If you let rain get in the engine bay the spark plug holes may be full of water.  Compressed air should blow it all out.  If you don't have a compressor a bike pump might do the job.
 
 

RED the car has spark, plug wells are dry

Wiso the pump connector can be accessed in front of the gearshift and can be accessed easily so I provided power to the pump direct and it runs. Good idea with checking grounds and diagnostic. Will give that a go.

+B has 12volts? if not check fuses
if it has get a multimeter
check connectivity of the FP wire in engine bay all the way to pump terminal under dash
and check connectivity of the other pump terminal to ground
 

 How do I check connectivity from Fp to pump terminal?
Set the multimeter to measure resistance (omhs)
connect one side to FP and one side to pump + terminal.
Use a long wire to get from pump positive terminal to the multimeter.
If the FP wiring is good you should get a very small or 0 resistance, infinite/high resistance means there is a broken wire somewhere.
 
Can check the pump ground connection the same way, 0 resistance to metal part of the chassis.
 
 

If you did it correctly, then it looks like you have a break on the wire going to fuel pump.
Also you shouldn't expect 12volts between fp and b, as fp is not a ground.
 
If you are defintely getting no voltage at fuel pump terminal under dash, with just ignition on and also with fp/b bridged.
Then I would run a direct 12volt feed from battery, and see if the car runs normally now.

Bugger, just when I was going to offer to take this (obviously) troublesome rally car off your hands.
 
Congrats on fixing the problem, though.
