Asked by Jan 30, 2015 at 03:43 PM about the 2007 Chevrolet Silverado 1500 LT1 Ext. Cab 4WD

Question type: Maintenance & Repair

so as I was heading to work the other morning my Silverado just dies! I tried restarting it a few times and nothing at first but then got it started again! now first thing in the morning it has a hard time starting I have to turn the key on and off a few times and even then now it seems like it still doesn't want to start even with doing that! it also still just dies once in a while going down the road but will start right back up it's just first thing in the morning that it has a hard time starting! has anyone had similar problems? or have an idea as to what it would be? I have talked to numerous people and have heard anything from fuel pump to ignition switch to just electrical problems!

Fuel Pump, fuel pump relay, crank position sensor, battery cable, ground cable, ecm, ignition switch and others. It would be helpful to find out if you are missing spark or fuel when it shuts off. Also do you have a check engine light on?

it starts hard first thing now but I did notice when I wiggle the ignition switch it starts right up! no check engine light is on I am pretty sure it is the ignition switch
