Update on my fist fire. Ls-1 in my 51 chevy pickup. Started the day with final checks then proceeded to install the optima battery I purchased last Friday. Got the battery in and nothing put my test light on it and nothing so off to the speed shop to get this returned. Battery in now and click click, took the starter down and performed bench test. New starter and battery and back home now. Truck is turning over but not trying to start. Pull fuel line off and no fuel pressure?? The pump is running but no pressure. Upon further inspection my new Walbro pump has a cracked line on the pressure line in the tank. Wow how did that happen? Brand new pump. Anyway off to Lowes and get some new line. Replaced the line and now i have several leaks in the line at filter and connections. Get the lines tight and now i have pressure and return flow. Tried to crank it a couple of times but it is late so cleaned the garage and called it a night. Engine is turning over but don't seem to be trying to start. Any suggestions or things you can think of ?? I'll check back in the morning !!
