intermittent start problem 2007 Chevy colorado

If it's not cranking at all you can start by checking power to the starter and the battery. If it's cranking but not firing and you are having an oil pressure light this could be an oil pressure issue or bad sensor. Make sure your oil light isn't an oil pressure light and not an oil level light. If it's pressure I suggest using a manual gauge to check engine oil pressure while running.
