Truck not starting after oil pickup tube o ring replacment

[Sammy1234]

Replaced my oil pan gasket and the oil pickup tube o ring on my 2006 sierra with the 4.8 vortec. It just cranks now and doesn’t start. My oil pressure sensor is also bad and I need to replace tht so that may be contributing to the problem, went over connections on the oil pan but they all look and feel good. Any ideas on why it won’t start?

It will start without that sensor working.

 

You need to check fuel and spark, make sure you got both. If it starts on a quick spray of starting fluid or brake cleaner, then you know it somehow lost fuel pressure.

Ok, Would the repair I did have anything to do with it not starting?

Did you miss a ground when putting it back together?

 

That's the only thing I can think of, there could be a ground harness not bolted down. Otherwise that repair is really straight forward.

Check the crank sensor connector.

Found a broken wire for the crank sensor, must’ve accidentally tugged it or pinched it somehow
