Messing around with things and I cut an FPR open, mainly for the mounting bracket, but also to see what the valve looks like. It's a steel tube mated against a steel disc, both highly polished and very flat. You can see how a little bit of crud or even just a hair could cause it to leak.

Got the engine started right away after following advice given here...started right up, but rough...replaced fuel pump, cleaned injectors...runs a little better but no throttle response ...feels like it is not getting enough air(?) I do not have enough tech know how to do the multimeter testing at the ecu so thought I would start next step by cleaning the MAF...is this a good way to go? and should I use any special chemicals? I have the Deoxit...mentioned in some of the posts I've read here.

What alternative throttle body options are available? Weber (and it's clone). 240SX Q45 Anything else? Anything that bolts up and has the same internal throat bore? What about from other manufactures? Doesn't have to be Nissan...

I pulled into burger king and saw smoke coming from battery area. I raised the hood and noticed the positive side of battery was grounded out on battery holder. I moved the battery enough to stop the ground and short. Now the car will not start. it will turn over and i have fire to the plugs. i do not hear the fuel pump running now. is there any other fusible links other than the 2 cap coverd one on the right fender. i have checked those and they seem to be ok. please help me:cry: scott

Hey folks - I've recently revived my 280Z and am working to get it back on the road. I've drained and replaced the old fuel - there was some sediment present, but I was surprised at how little. The car turns over and starts easily, and idles like a champ, hovering around 850-900 RPM (it's an automatic, just fyi). However, when throttle is applied, power drops, the car will rev to 1500-3000 RPM or thereabouts and then pop, stutter and basically drop dead back to idle. The car never dies during this time. The existing fuel pump wails like a banshee. I'm not sure if it's an OEM pump or an aftermarket junker. I do have an aftermarket pump on-hand for temporary use, a…

So if I understand this Tech Tip courtesy of Blue, counter clockwise leans it? Clockwise richens? Mine is running really good and temp is cooler, gets great gas mileage but my plugs might be a little dark. So I think I should turn it counter clockwise just a scratch, correct? http://atlanticz.ca/zclub/techtips/tempsensorpot/index.html

Hey guys/gals. I just wanted to drop a line and say HEY ! After being away for a little while. Unfortunately I had to sell the ol' Z recently. ( actually I traded it for a Volvo :stupid: and sold my E.F.I. equipped 72' Celica too ) in order to move me and the family out of state. The good news is that shortly after hitting the ground here in Georgia, I landed a job on the Tech Support staff at DIYAutotune.com. ( http://www.diyautotune.com, if you watch the photos at the bottom, that's my Orange 280 Z ) Most of you probably already know us, but in case you don't DiyAutotune.com develops , builds, sells the MegaSquirt brand of engine management systems, and I'm sure…

madkaw, I don't know if you have done this on another forum, but would you consider starting a thread documenting your MS conversion or just use this one. I don't spend time on Hybrid Z anymore and would find it interesting and possibly helpful in the future to follow your steps to converting over to EFI. I love the look and sound of triples but as I get older there are some aspects of EFI that I find really appealing... Charles

Well its summer time and time to get the ole lady under the knife. I bought the car ~6-7 months ago with alot of work already done but now i wanna take her to the next level The car is a 74 260z with a l28 swap and holley 4 barrel conversion The previous owner used to autox her so i guess that justifies the carb conversion but i plan on using her more for a street car. So now comes the swap and my ignorance. L28's came with EFI correct? But early model 260z's didnt. I am well aware that ill need a stock intake manifold and fuel rail but am unsure of whats next. I plan on replacing the rusted out stock fuel tank so il be going witha fuel cell in the rear and wil…
