...won't start? the problem is the fuel injector will not pulse.the computer is good..the ignition module is good any ideas...
 
If you are getting spark, then the problem is you are not getting gas. It could be the fuel pressure regulator or fuel pump.

If you are getting gas but no spark and you have checked the module, you might want to check the coil or distributor.
 
crank sensor is what pulses the injector,make sure you have a good connection at the module.
 
if the injectors won't pulse one maybe bad . the coil in the injector might b shorted. i would ohm them and c if one is bad
