Question about Cars & Trucks
I have a 1994 Chevrolet Suburban. It had a flat lobe on the cam so I replaced the cam, lifters, timing chain. Now, I cannot get it to start. I know that the cam and crank timing gears are aligned correctly (both marked teeth aligned, and the timing line on the harmonic balencer on the 0). Adjusted the valves according to the book, but the truck will not start. Any lhelp would be very much appreciated. I also zeroed the computer.
Check the crank position sensor and cam position and wires are connected
reset the ECM using a scan tool that has the protocols for GM

Yes be sure the number one piston is at TDC firing stroke or compresson stroke and line up the timing mark pointer is pointed at exactly zero. One more thing when aligning the camshaft sprocket or sprockets be sure that when you are rotating the sprocket for the cam it is rotating in the correct direction and also be sure you observe the intake valve for number one shutting as you bring the marks up to alignment points, the intake valve and the exhaust valve should be shut when the marks line up if not you could have the cam sprocket off 180 degrees, get it right the first time or you may damage a valve trying to start.

Install the cam sprocket, timing chain, and timing chain cover. Make sure the dot on the crankshaft gear is pointing towards the center of the Camshaft gear bolt. Make sure the hole in the Camshaft gear is pointing towards the center of the crankshaft. Be sure to remove the nail holding the chain tensoner back, before installing the timing cover The round hole in the cam gear is the alignment mark
