Cranks but wont start

I believe there is a crank sensor that allows the fuel pump to send fuel to the engine. If the sensor is bad, it won't start.

Possibly the spider injector unit... Upper intake manifold has to be removed to install this part. This is the symptom especially when they get old. The upgraded spider injector system has electronic injectors at the ends of the injector tubes instead of a central injector like the original unit.

Sensors shut off fuel pump in event of accident, also check oil pressure sensor as it will also interrupt fuel pump circuit

i have a 1998 gmc cargo van the starter went out he bolted the brand new starter out of the box on trucck then put the starter cable on it and shorted the starter out by smashing the alignment cab out across to the ignition terminal and now the van won't start I put another starter on it from a junkyard
