80 gmc no start - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 80 GMC just quit when I went to go to the lumber yard. I had bent the contact on the rotor button to make better contact. I ran it for a while then it just quit. Since thi s I replaced rotor button with a new one. When I crank it I see that it's getting gas , but it will not fire. It has new plug wires. I replaced the ognition module.and am going to try another coil. I'm just wondering, if I could have a broken timing chain. I've noticed after I had a new short block installed that, occasionally, when I drive the motor cuts. I even noticed it happening a couple of hours before it just quit. How can I test for a broken timing chain? Thank you for any feedback on this issue.
