My gmc safari wont start. I was driving and it lost all power. would not start back up. replaced fuel filter and spark wires.

Remove a plug wire. install a plug . lay it on the intake and have someone crank it while watching for spark. no spark. turn key on see if your fuel pump comes on . you should hear it. If not you could have one of two things bad.Ignition module which is inside dist or crank sensor by the crankshaft pulley. hope this helps. you can have the module tested at oreillys or auto zone.

Is the engine spinning when you turn the key?If so check the fuel pump! Good Luck!

Check for missing or loose ground.its electrical problem.don't waste money on fuel pump replacement

Looks like u needing a full diagnostics check
