Clio dci

[m0hxt]

I have a Clio Expression+ DCI 65. I have removed two
of the injector pipes today to get injector No4 out to replace the seal and have
put it all back
but can not start the car now it will run for 30 seconds and stop. when it is
runing it is only runing on two.
injector 3 & 4 are not work ie if i remove the wires on the injectors it makes
no differance will still start but only on two if i take injector wire 1 or two
off it will not start. I have been told that if i put two new or
used injectors in thay need to be progamed in cpu.
Can it be reset in any way as to make the injector 3&4
will work with out changeing them.and if i put new or used will it work with out
progaming so it can be taken to get them progamed???
any help please
