'99 S-10, No Spark

Just replaced fuel pump and now no spark. It has an alarm and have been having problems with passloc. Could that be it?

Yes It Could Be Pasloc It Could Also Be An Electrical Problem Such As A Crank Sensor Or Even An Ecm

here is somethings to check, battery and connections, check for spark from coil if there is spark check cap rotor plugs and plug wires. if no spark from coil check for too wide of air gap in pick up coil or defective pick up coil, loose or broken wire in primary circuit, defective ignition module, or a broken distributor gear or drive pin.

Stupid me! It was a fuse. Sorry for being unobservant.

that would do it.
