97' grand voyager wont start!
 

my 1997 grand voyager will not start, i have read some threads about the immobilizer but thought i would ask about my problem.
i have just got the car on friday and it had an aftermarket stereo fitted but this was removed, so i got a new stereo and went to fit it. the original sockets had been cut off and iso connectors fitted but the wires had been taped up, so i removed the tape and the wires came apart. after i did this the car wont start!
all of the dash lights come on apart from the alarm light.

any help would be appreciated.

many thanks
