Just set the meter to resistance and bung it on the terminals, i cant remember the reading but you will soon see if its gone, you may have to change to a resistance band of higher than 200 ohms.
If there is no resistance reading it has gone open circuit.
Let me know how you get on with that first......

No you want to test the actual sensor. So you need to pull the plug off, and test on its terminals (the reason for disconnecting the plug is the meter will more than likely give a reading for the components inside the EDIS4).
It may be tricky to get at it, its got a single torx bolt holding it in if you can get it out?

Hmmmmmmmmm, sounds like an ok reading.
Next test (your guna love this)
You've got to somehow hold the terminals on the sensor, while at the same time being in the car to turn it over...........
Set the meter to AC volts, and you should get a voltage reading. (unplugged again)
(Probably wise at this point to employ your glamorous assistant to turn the car over
)

Double check that resistance reading, just incase you had the probes touching or something.
You should see a substantial AC voltage reading (check you were on AC volts not DC)
You could also take the sensor out and wave something like a spanner past the front of the sensor, needs to be very close though.
There was a thread some time ago where someone had an XR2i which just suddenly stoped, his CPS wouldnt read the timing marks on the flywheel but would read metal objects passed in front of it, he never replied with the fault though

ive just tested resitance and while still in car and it was the same reading and the pins were definatly not touching also i checked voltage and it came up as 0.09 when had multimeter set to 200 volts ac and 0.01 when set to 750 ac

Ah right if its on 200V AC then thats a reasonable reading....i think lol
Might be worth checking fuses next then......if the main ECU fuse has gone then i dont think the pump will operate. Could be your ECU packed up?

the fuse hasnt gone but the car hasnt run since the conversion so dont think it will have had chance to go unless it had gone before i bought it
is their anyway of checking the ecu

ive done voltage and resistant checks on the ignition coil , crank position sensor , edis4 and ht leads and their all fine ive also bought new sparkplugs (motorcraft) and it still wont spark it just cranks over and over and theirs no spark at all
any ideas mate ?

I have a spare 1AFA ECU, (asuming yours is not turbo)

definate the fuse hasnt gone but havnt tested relay as i cannt work out which one is the engine control relay as its not listed in manualas having one
how much do you want for ecu inc postage and does it defo work
also could it be a weak starter as it doesnt seem to crank as fast as it should but that could just be me lol as wouldnt this affect the crank senor not getting a correct reading

There should be a control relay. Did you say the engine is a transplant? The relay is usually red.
If its not cranking over fast enough then it is quite common to cause problems as the CPS doesn't produce a good enough signal for the ECU to work with, but however seeing as the fuel pump doesn't run either that would point more to the ECU being at fault.

theirs 1 red one which is about twice the height of the others but its listed as wiper delay relay apart from that their aint one and in the maual the only other relays that arnt to do with the lights or heated screens are
cfi delay relay
ignition switch
automatic transmission starter inhibitor/electric fuel pump(bridge fitted to carburettor engines without automatic transmission)

check the fuel pump relay under the dash i had a simular prob with my frst i drove around with a perm live runin 2 my fuel pump from battery for a bit till i realised what it was

I stick reckon ECU though.
The thin wires is a good suggestion too

thin wires are fine
the only red one ive got is the wiper one i have a green one next to the yellow one ( fuel pump) the green one is ignition switch which will activate the fuel pump relay ie when it primes

do you reckon if i get the red relay it will work can the relay be affecting it though as it clicks each time i turn the ignition and everything on car works apart from spark and pump
also whats IIRC mean

Just to clarify is this a totally original XR2i or is it a transplant cos ive got this trnasplant idea at the back of my head.
IIRC means If i remember correctly
sorry

Hmmmmmmm
Thats wierd. What wiring diagram do you have then mate? JUst wondering? Theres a variation on that red relay, like a revised relay i think, but should be there
