Re: No injector pulse
Check for a bad pickup coil and/or ignition module either will cause a no pulse condition.
also check the bulkhead connector on the firewall to make sure it does not need to be repinned.

Re: No injector pulse
Pickup coil would be spark side for plugs so thats probly ok ign module would be pulse side for injectors i would start there check for loose connectors crimped wireing and all the basic fuses/relays ect
