Question about 1999 Chevrolet Silverado 1500
Truck shut off while driving, Did continuity check from positive battery cable at post to truck body found continuity. Disconnected POS cable going in distribution box and performed continuity check on post going in distribution box and truck body found continuity. Removed all fuses and relays, did continuity check on each fuse slot. IGN-1,ECM-1,HORN, and ENG-1 showing continuity. Where do I go from here?
Chevy trucks had a bad habit of shorting out near the starter. It shorts out because of the hot manifold melting the insulation. I moved my wire away from the starter and placed it on the battery positive post using a small extension. You might also have a bad pickup getting ready to go so be ready.

Check the wires to the distributer or to the modules could be poor or no conection. If you can turn the car over but no spark it's probably something to do with ignition, distributer, module, or wiring to the ignition.

that fuse feeds power to fuel pump relay circuit that feeds pump could be defective pump,or damaged circuit wires that shorts out! and not a good idea to put higher fuse in circuit could cause more damage to circuit! but i know when your stuck, u do what it takes,so inspect circuit related to fuse,

At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck
