Few days ago i accidently cracked what it seems to be fuel return lines. Correct me if I am wrong but they are near right(passenger side rear) fuel tank. 4 Lines are steel lines with pair being different diameter.

Out of emergency method to stop the leak i put some of those steel putty over the line. I havent started my car since last week. I was working on my interior conversion. However today car wouldnt start. I figure that there may be possibility of after market alarm I have put in, I took everything out and made it stock.

When I turn the key over what I hear is fuel pump turning on and some relays clicking. However the engine would not turn at all. No cranking sound nada. I havent checked out starter or solenoids physically but I did turn on my headlight if they would deem during starting, and it was just bright as before. Not too sure about relays because I just swapped them around to see if they are good to go.

Only major thing that I have done past week was that leaky fuel lines. I didnt replace them so I was wondering if it can cause our cars not to crank at all. Theory is that comp reading lost pressure at the lines thus shutting ign off. It is just a guess but it would help a lot if someone can chime in here. Thanks !

lol @ thread title... Check your battery voltage. Probably drained it out with the dome light leaving the door open or some sort of parasitic drain.

already checked battery, it does have plenty of juice. I actually disconnected everytime I worked on my car and just in case I did some jumping but it did not start.

fuel line has nothing to do with it. electrical problem...start diagnosing it.

okay fixed fuel line and found out that the problem was the ignition switch. It looks like the previous owner hooked up the 12V constant and ignition wire black/yellow with a switch to get it working.
