In this video I will walk you through some basic tests on verifying spark, injector pulse and fuel pressure. All you need is a digital multimeter and a small pocket screwdriver. I will be using the Power Probe IV but this is not a necessary tool to handle this problem.

In this video I will show you how to test for spark on a GM type two waste spark system. How to test for proper fuel injector control and how to test fuel pressure and the fuel pump electrical system.

This video covers the basics of fuel pump pressure, current, power and ground testing that can be applied to ANY electric fuel pump.
