How can I tell if my spark fuel pump is bad?
Testing your Spark’s fuel pressure on each side of the pump would be the best way to diagnose this problem. A priming fuel pump sounds like a high-pitched whine for a few seconds and can be heard with a sharp engine right after the ignition key is turned, but before the starter is engaged.

What to do if your fuel pump does not work?
If that does not work…. then you might have a bad fuel controller/pump. Listen closely when you turn the key to the start position and see if you hear the fuel pump pressurize. If you don’t, run a wire directly from the battery to the fuel pump and see if it starts. If it does. replace the fuel pressure sensor. Have the battery checked.
What causes a Chevy Spark to not start?
If the fuel filter has become so contaminated that the minimum amount of fuel has not been let through it, the engine won’t start at all. At the most basic of levels your Chevy Spark needs three things to start: Air, fuel, and spark. If any of these things aren’t present, the engine won’t turn over at all.

What to do if your fuel pump won’t start?
Tried to start it with the pump running and it wouldn’t start. Then realized that the multi function unit probably needed to be plugged in for it to run. Plugged that back in and jumped the fuel pump from the inertia switch and it still wouldn’t start. Then checked the spark. No spark. Checked all the fuses under the hood, all ok.
