new guy in a bind Thanks for the membership. Working on my bosses 00 Yukon 5.3 witch was fine till he complained of morning rattles. So he gets roller lifters ,double row timing chain, towing cam just more duration, rockers , cam sensor and crank sensor, plugs and the coils were replaced right before this. He had codes p0351-358 prior to work but the truck ran fine. Since work starts fist start every time but if killed and restarted it spins and pops like its out of time if it sets for 30 min. its starts fine . OK I've changed the cam sensor and checked the square wave good. I've got fuel pressure 55lbs. ish with no bleed down. spark good ,crank sig, compression, anti theft, all grounds re done. checked timing marks its in even took cam out and made sure pick up for sensor is the same and no damage. however only difference is new cam is slightly magnetized. help...
