#1569403 84 720 starter or ignition problems?

Posted by Toxicrain on 09 June 2018 - 10:55 AM

when you turn the key is there just nothing from the starter? Check for loose cable at starter and replace the ignition switch would be the first steps. you could always hook up a push start button for it and bypass.

#1569183 720 Weber z24 WOT dies out

Posted by Toxicrain on 07 June 2018 - 02:26 PM

It sounds like fuel cut because your on a hill and gunning it so your using whats in the fuel bowl and the stock pump isnt pushing enough gph to supply going up hill. I will suggest the carter 4070 pump because it is a high gph 75gph low psi pump perfect for webers as its output is about 5psi and get a good fuel pressure regulator i suggest holley 12-803 with any low psi 1-10 fuel rated pressure gauge hooked right on the front side of the fpr so you can pop the hood and easily see whats happening. it might be pricy compared to stock stuff but ive been dailying this setup for 4 months now and ZERO issues at all.

The temp gauge is a VERY common issue with 720s there are many forums on it.. your thermo is most likely sticking open. put a higher temp thermo on it and it will raise it up a bit. many gauges read about that on street and when on highway mine goes under the 2nd squiggly thing i believe i put a 185 in it.

you can also place the pump lower than the tank to gravity feed it better.

Do an inventory search before you go. The Sacramento area pnp’s are pretty crazy, if it’s been on the yard more than a week or two, they’re usually completely stripped.

yup row52.com search under datsun pickup not under nissan pickup because those are all the D21's.


Check that daily and the second you see one get down there and get what you need will be gone within a month


I signed up for the emails so I get notification right when they get a 720  near my area :D

Enjoy the pops!!! As long as you have some amount of pipe on there there is basically no danger of bad stuff. I like the exhaust I have on my 2wd (you can hear it on you tube if you want). Mine pops only sometimes or when I want it too, it's the perfect balance. If your not doing emissions just run a long tube glasspack and some pipe, then it won't rust and is cheap. Would recommend at least a welded muffler/glasspack I don't like press together but each his own.

cool man thanks for the info I just didnt wanna break something and yea your truck sounds poppin  :thumbup:


yea no more emissions for this truck lol ... i might just get some new headers as the stock ones lookin crusty and Ill be able to do egr delete easier and from there I can just 2 inch all the way back or somethin cool..

just an update been about a month now and the truck is running great! daily driven it 50-70 miles a day in various weather and have driven it in 90+ degree weather and I dint have my fuel cut, boil, vapor lock or any bogging issue that I had before the carter pump and holley fpr install. gauge always stays at a steady 3psi. Just want to thank you guys for the help in this thread and now I can save up money again instead of it all going to gas.. ($300 a month in gas better than $500 when driving the dads tundra  :sick: ) damn prices keep going up too $3.79/g from 3.07 back in January...


Looking into things I have been adjusting my throttle cable trying to find the best cable springiness and what not..

I have noticed that on deceleration now I get backfire. now my exhaust is setup with nothing past the eBay cat that the PO put in. Stock headers. I took the muffler / tail pipe off because it was rusted out.

I have tried to set the throttle cable forward more to reduce the back fire but if i set it too far forward then when i put the truck into drive the idle shoots up and ill be going 15mph without touching the throttle and when coming off the highway or to a stop I wont have any engine deceleration which then I gotta use brakes more..have to brake harder to stop etc..


Anyways. Just wondering if that backfire will destroy my engine or not overtime. I only let it happen when i'm almost at a stop and its only when my foot is completely off the pedal. when im coming off a highway or something ill left foot brake and keep my throttle inched before full deceleration to stop it from popping  ..


I dont think its back firing into the intake as I have had that issue before and It is definitely a different sound. Hopefully its not shooting flames under the bed when its popping because I do run my truck slightly rich to compensate for driving at 80 so I dont get any bogging when trying to floor it at those rpm's 


Eventually ill go to a muffler shop and get something installed but the truck isnt obnoxiously loud and cops havnt pulled me over for it yet so ill let it be for now and work on my 89' camaro.


me being a teenager I kinda do like the pop sound :D and hopefully when the exhaust is completed it will be louder cuz im just trying to have fun with this truck now since I can only drive it until Aug 2019 (rip smog with weber carb)

I have almost the complete a/c off my 81 720 parts truck if you need any parts I can ship to you. It does take a lot of work but well worth it!


I would check out that truck and get parts before its gone in 2 weeks.

#1553360 Sensor light

Posted by Toxicrain on 24 March 2018 - 07:36 AM

My 85 has a sensor light and a couple inches down the wire there is a tag saying i think something about seat sensor and it turns on after 90k and then you reset your battery and then it turns on after another 60k and then your supposed to unplug it which i did when the light came on and havnt had an issue with it since.

#1551439 How much do drive your vintage Datsun???

Posted by Toxicrain on 14 March 2018 - 08:04 AM

I got 12k miles on my 720 ive had for about 9 months now i was doing about 800 miles a week but now I am trying to not drive my 720 as much because I don't want it to blow up on me ( drive to work is 40 miles along hwy 1 at 80 mph) and I feel like it is meant to be a Sunday driver or a weekend vehicle.

If they had an adapter plate for z22 with 4x4 5spd trans to a 85 rwd z24 I would have 5 spd swapped my truck 6 months ago. Oh well hopefully ill find one before the motor blows (140K)and im thinkin of Ka swap.

captain, I believe they are the same as the intake bolts.


I thing the problem is I bought a set of studs that were the correct thread pattern, M8 x 1.25, but some idiot use a bolt with a similar but different thread pattern and that kept the studs from threading properly.  I just wanted to check before i get an M8 x 1.25 tap and try and clean up the problem.  




I can get you a correct thread and pitch but it wont be until Saturday because ill take a bolt off friday and match it up at my work. Im sure you will have an answer by then though. that sucks that the PO had not done it properly. Part of the reason im afraid of buying used trucks because of the hack jobs people come up with including myself. Hope that your tapping process doesn't have any problems :)

i also put a vinyl wrap on the grey piece in between the cluster and the cluster itself i used a blue carbon fiber vinyl. and i used some nail polish to paint the needles of the gauges blue. and the green turn signal plastic piece i used a old coffee can that was blue cut the out with an exacto knife and now my turn signal blink blue instead of green :) i laso changed all my lights to LEDs so they are a little bit brighter

Links? Pictures? I just had my cluster out sunday and i fixed the Trip odo (peg fell out of place and busted it apart pretty much... nothin good ol super glue wont fix :D) I was thinking about coloring it or changing the bulbs but I need to focus on mechanical problems rather than cosmetics right now..
