2004 Silverado 4.3 v6 distributor issues

Postby Redsox18 [OP] » Aug 27 2020, 5:00am

So,
A few days ago my truck backfired loudly and I lost all power and would not crank. Got it back home and hooked up to OBD2 reader. Shows code of camshaft position sensor and MAP(img attached). So we put a new distributor in, and it started and ran but could tell timing wasn't perfect, but wasn't bad. So we decided to Top Dead center the crank pulley again and reposition the distributor to get it perfect. So, put everything back together and of course being late I forgot to hook up the camshaft sensor, and tried cranking the truck. Wouldn't start obviously, hooked the sensor back up and still won't start whatsoever. Any ideas, insight, help, etc you guys have would be greatly appreciated. I am no mechanic but I do try and learn to do these things for myself.

What led you to replace the distributor vs the cam position sensor itself? Did you check the connections and wiring to the O2 sensors for those two fault codes?

Replaced that sensor roughly a month ago. Fixed the issue that I was having then. When it threw that code again I figured it's time to put a whole new distributor in. O2 sensors are not plugged up due to someone being lazy with after market exhaust.

Did you use an OEM / AC Delco camshaft sensor or aftermarket?

It was bought from O Reilly I'd be lying if I told you the brand. I do know that it was good, but the rotor cap was broken into a few pieces and that was the overall issue. Now, even though we take it TDC, the oil pump shaft will not line up. Nor does the piston when on Top dead Center. We are thinking that it may have jumped time and that is why we can't find exact TDC and get the job done.

Are you sure you are on the compression stroke and not exhaust?

Yeah, positive. Put my finger over Plug #1 hole and waited for it to blow my finger off, then achieved what we thought was TDC. Wasn't actually there even though we had pulleys and marks aligned perfectly
