Problem remote starter

 I installed a prostart remote starter a little while ago in my 2002 calviler standard .It worked fine now it won't start . I can put it in ready mode but thats it .I here the fan and fuel pump come on but it won't crank .I checked my wires all are still connected . fuses are ok . Bypass works (   learning bypass). I am at a loss the manual gives no help I reset the module and still nothing .

Any help would be welcome Thanks in advance      

 I checked all my connections fuses even replaced just to make sure. when I put it ready mode instead  of the parklight flashing three times it flashs about 5 or more before the lights stay on for ready mode . I exit the my car press the remote to turn it off . and when i press the  remote to turn on the park lights flash I here the going through the prep to start and then it stops and the park lights flash three times and thats it .
