ok, this is a big pain in the butt. I am getting spark all the way to the plugs. now, no power to the fuel pump. Wouldn't I hear it turn on when I put the key to on? Also, is the stock fuel pump in the tank? The car is a 240 w/ L28 and T5 trans. SU carbs and distributor module. What the :tapemouth is wrong with my car?? I love this car, but she is really being a pain! Thanks, Brian:alien:

Where is the stock fuel pump located? Also, the car is equipped (I think) with an external fuel pump. Where would I start first? Brian:alien:

Ok, this is my first car, I have no idea where to adjust the carbs at? :stupid: I use to own a '96 Stratus, so I can't say that I know enough about the car. By the way, what is the fire order of the spark plugs? Thanks, Brian:alien:

I got my project from a guy I work with. They put a L28 with T5 trans. I went to the ends of racking my skull finding out what the :tapemouth was wrong with her. Now I think the fuel pump isn't getting power. If I'm not mistaken the pump should kick on in the on possition before you go to start? My return line to the tank is leaking where the hose meets the clamp on the tank. I noticed a puddle of fuel just below it. Also, could it be some vacuume lines on the SU carbs rotted and not functioning right? Brian:alien:

:dead: :stupid: :tapemouth Now I think the problem exists in the fuel area. I have spark all the way to the plugs. I pulled the fuel line after the filter and tried to crank the car, No fuel. I have also found that most of the lines on the SU Carbs are rotted and so is the return line to the fuel tank at the clamp. Could it have only been the vacuum lines all along? Brian:alien:

No, Steve, the car sat for about 4 to 5 months. He said that the hot wire to the coil might have a short to it?:tapemouth I thought I should try to trace the wire back to its oragin to see if this is true. thanks, Brian.

The engine will crank with the key, (now that I've installed an Optima "Red Cap" battery) I changed all the connectors to the starter. They where green.:stupid: Now the engine will turn over, but no spark. could there be a short to the coil, or should I try putting the old coil on? Brian:alien:

I have just aquired a '72 240Z with a 280Z L28 engine. Here is where it gets tricky.... new sparkplug wires, coil, and Optima battery. Still not cranking. It all started with me and my wife trying to jump the old battery. We got a quarter of a crank but that was it. Then the next step was to put the new battery in. NOW from the ignition, I don't even get a crank. I can hear the (I guess) starter relay clicking but nothing to the starter. Took the starter off, works as advertised. Put the starter back on, still nothing. Then back to the starter....I put the jumper cables on my other car and took the - and mounted it right to the - on the starter. Then taking the + side of the jumper cables and touching the + side of the starter, I'm getting the same quarter of a turn and no juice. On the instrument panel, all the bells and lights work. BUT NO JUICE??? If I took the sparkplugs out of the engine and try it the same way would it even matter? (maybe the chambers are full of gas?? Thats the last troubleshoot opinion I got...) think it will work? Thanks for reading my problem......Brian
