Posted May 13, 201113 yr comment_355588 Our reassembled 260z engine was finally started and pegged at 1400 rpm. Got her down to 1000 and she sputtered and quit. Now she isstarved for fuel. I pulled the line going into the mechanical pump andit was bone dry. I had to call a time out because it was getting to me.One other thing the vacuum at 1400 was 15 inches and steady so Imust be close. Someone tell me where is #1 located on the cap forproper firing order? Are there pictures on the web that show it?

May 13, 201113 yr Author comment_355661 I took my air hose and shot some into the fuel line back to the tank and also going to the carbs. Think my starter windings are heating up so I will get another but for now the battery is getting recharged. I will post some pics later of the crank, distributor and rotor and wire positioning.

May 14, 201113 yr Author comment_355710 With a fully charged battery it looks like all we need is fuel. There is gas in the tank but not much so with a small can and some hose hooked directly to the mechanical pump we will try to start her. If that works I go to the tank and pull the lines and blow them out.So much for Friday the 13th Link to comment https://www.classiczcars.com/forums/topic/39554-perplexed/#findComment-355710 Share on other sites More sharing options...
May 14, 201113 yr comment_355734 You can operate the fuel pump by hand if you remove the valve cover, pull the lever several times to prime the system. That will keep the starter from spinning so much.Bonzi Lon Link to comment https://www.classiczcars.com/forums/topic/39554-perplexed/#findComment-355734 Share on other sites More sharing options...
May 14, 201113 yr Author comment_355741 I pulled the pump and valve cover just to make certain that the eccentric was not loose. I remounted the pump flush with a new gasket without a spacer. There is 4 gallons in thetank but nothing at the pump. With a charged battery she cranks strong and on startingfluid no bacfire and clean at the tailpipe. For now once she gets running I just want to besure there are no leaks and she holds a steady idle and vacuum. I will try posting some pics today but she ain't pretty outside.

May 15, 201113 yr Author comment_355807 I primed the pump she fired right up and held 20 inches of steady vacuum at 1000 rpm and ran until she reached midpoint on the temp gauge. I still have to sort out a fuel issue because she starts dropping rpm. There were no visible leaks and she idled smooth with a clean exhaust. We did not try accelerating because we wanted her to maintain idle first.We will load photos and video later on Photobucket. We are closer Link to comment https://www.classiczcars.com/forums/topic/39554-perplexed/#findComment-355807 Share on other sites More sharing options...

May 15, 201113 yr Author comment_355890 Well if I prime the mechanical pump she fires right up and runs off the gas can smoothly.She is up on ramps so I shall pull the pump and hoses off the rear and blow everythingout. So with gas in the front I can reconnect the lines and since she is at 800 rpm therear pump will be on and we will see what happens.

May 16, 201113 yr Author comment_355925 Our Z has a leaking front cover I need another, cleared restriction in fuel system she starts up, brake pedal spongy and rpm go up when applied, hold steady 17 inches of vacuum drops to 14 when braking, fair acceleration up to 3000 than flat, the engine temp is good and so is the oil pressure, does not deisel on shut down,occassional she backfires on hard accel. How close am I???????????????????? Sounds like maybe I ama tooth off on the distributor so advance is lagging and I need a timing cover anybody.

May 16, 201113 yr comment_355968 If you are getting plenty of fuel, the I would check the TPS and the AFM. Look in the downloads section (top toolbar) and get the Fuel Injection Bible and check your settings. Backfire on acceleration, etc. has me thinking the AFM needs testing.
