Hey guys! Looking for some direction on a strange engine issue.
Had my 5.3 litre rebuilt about 7,000 km ago (rebuilt at 198,000 km) Engine has been running great up to this week. Got 5 min from home and truck died, experienced sluggish/powerless seconds before pulling over.
Got it home and there is no engine codes. Looks like we have blow by when we open the oil fill cap however did a compression test and we have 160-180 psi across all the cylinders.

Engine oil smells like gas now and there’s lots of cranking power it just won’t start. We checked the high pressure full pump and it seems to be operating correctly….

Any help would be appreciated…
Thanks

 

Welcome from Florida. You might have bad gas contaminated with water!!

 

Thanks Florida! That did cross our minds… We’re gonna drain the gas tank today….

 

Are you getting spark?

 

Lots of spark. Checked all of them
