when you unplug the "temp sender" (water temp sensor?), the ECU will get an infinite resistance reading causing way to much fuel delivery this will stall the engine. Did you get a wiff of gas?

what are euro bumpers?

ditto on checking the fuel pressure. You may have clogged fuel lines. If there is rust in the tank it can clog the fuel pump inlet. You may have a fuel pump that is close to dead. but it sounds like clogged lines.

wow those look preaty close to stock.

I had the same problem. The ones from BD are for the 240/260. They probably would fit but not look quite right. I lucked out at the junk yard and found a pair in good shape. How bad is the rust? can you grind off all the rust and recover them?

ewwwww :sick:

Cool Looks like all of us with EFI share similar stories. The cool thing is that after pulling out your hair trying to solve these problems it turns out to not be that hard to fix and we become more knowledgeable about how this system works. In my case where the P.O. Hacked the system my making adjustments in order to compensate for a greater malfunction (leaky manifold). or making "mods" (as if they know better than the Nissan engineers).

He can shoot lazer beams out his eyes.

Is the Z34 not the Z for you? sorry stupid joke. I know how you feel I had a 260 I bought in 1989. I got rid of it because I really did not know much about fixing Z's. Ever since, I had kicked myself for sending it out to the wreaking yard, It had no rust. So to make up for it I saved a 280 from the junkyard 3 years ago, the PO was going to have it towed away. So for $300 I saved a rust holed 280 from DEATH. I love My car.

ummmm ok Something new. BAD water temp sensor. I was suspecting this the last few days. I should have listened to cozeye. I took out the temp sensor and put it in a pot of water with a thermometer and tested the resistance. I got a sideways 8 (no my meter does not really show that). So off to the parts store I bought a new one and tested it for fun and the readings were all spot on. Put it in the car and now the car runs great! I am thinking of putting the spring tension back to the calibrated setting and calling this thing done. But I am still going to look for vacuum leaks and there is a sticky spot on the afm, about 3/4 open it sticks, I am wondering what to do to rectify this. Hmm.

You're car makes me :sick:

I have been sprayed in the face not fun! Try this: locate the cold start injector and use a 9 volt battery to activate it. This should relieve the fuel pressure. BUT when you remove the fuel line from the top of the filter remember to do this slowly just to make certain you have relieved the pressure. Also you may need new hoses and hose clamps make sure both are rated for fuel injection systems, I am not sure why part stores often do not carry the hose and the connectors are even harder to locate, they should be common seeing that most cars these day are fuel injected.

The boss at work (General director). Saw me get out of my car for the first time last week. He asked if I restored it myself and I said yes commenting that I bought it for $300 bucks. He said cool it looks like a corvette! he is the boss what can you say?

Ok my last calculation is 18.5 mpg. That is mostly in city and some Seattle freeway (these days that is stop and go). So not to bad I think. But at times now my engine sputters and I here a little popping on deceleration. Could this be lean due to leaky manifold?? My car did not due this till I made my adjustments.

Wow that is a clean car.

Is you're car in the golden gardens pic I can't find it. Mine is the yellow one.

Was it running better before the new exhaust? could you have a mainifold leak?

I had the exact same problem on my 77. Still not sure what caused it. I took apart the switch, cleaned the contacts and pulled the little spring that puts tension on the copper contact thingy to give it a better contact. My turn signals work great now. But this was after I took apart the high beam low beam switch, I mistakenly thought this was the culprit and in the process the contact plate crumbled apart :tapemouth Now I need a new one. Dave? can you help?

Sooooooooooooo....... It is to early to tell so far, but since I had to back the tension off a little to make it run right, could this mean that after setting everything back correctly that I could have been running lean!!! putting my car into the same scenario as Yours? (Fastwoman's and Coseye's). Oh and did blue do the write up at Atlanic Z? whoevere did gets a huge thanks also.

That's what I was thinking, straps. but I would even go with larger ones than those. They may be strong enough but as the first post pointed out, Fingers are a good thing to have around for life.

Or road warrior, If the roof hood did open. You could mount guns inside. just pop the roof hood and fire away. Note that it would open out the rear so I guess that would be the tail guns.

it was 12 teeth to loose I moved it 12 teeth CW but backed it off about 4. So in all I tightend the spring by 8 teeth.

I just about peed myself laughing.

Ok, I ran my the 10 gallons through. I calculated 16.7 MPG. Hey quite the improvement! I have adjusted the AFM both the wiper setting and the spring tension with 148 grams of weight, it was about 12 teeth off. the car seemed to be a little gutless so I backed the tension down about 4 teeth, Wow what a difference! I thought the car was running good before. Now it seems like a different car. 10 gall added and I will calculate again my mgp. I think I am there now! Also I will pull the plugs look at them clean and read them again after 100 miles or so. Stay tuned and thanks again.

Is That a hood on you're roof?! how many gallons of bondo are you up to? Though I like the stock look you're car actually looks well.... sort of cool. have you looked up the ratsun site? A klingon Z of prey.
