There are two sets of fuses one for each bank of injectors.Since your getting the pulse signal from the distributor module, it sounds like that might be where to start.Check to make sure there is powere to the fuse as well. MY 86 didn't pulse either-it was the ecm.If there is no light at the injector check ecm connections,( that screwed me up-the connector to the ecm about 6' "upstream" had come partially undone) if there is a light it could be the new ecm .
The engine control by way of the ignition module.
The engine computer (pcm) controls the injector pulse. It looks at numerous sensors and switches to calculate pulse width
1990 ford ranger 2.3 no injector pulse what causes this
200 Nissan exterra v6 have spark and injector pulse no power to fuel pump
tools u can use are a noid light....or an injector pulser ''TOOL''
Injector pulse is controlled by the ECU. Injectors Have a red wire that is hot. Black wire is controled by computer ground...
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
Try changing or checking the oil pressure switch next to distributor if it goes bad the engine will not fire or start. Motor (ECM) has to see at least 3 psi of oil pressure to start. And will also shut down if less than 3 psi.

faulty crank angle sensor in most cases
The engince control computer. Why ?
