Ok so the last few weeks have been hell in the Datassuns world .. Few weeks ago I wake up early Saturday morning, go pick up a buddy from north Austin , and then change the spark plugs and go to wash the car . When I get to the car was (the Gene on South Lamar) The car is running fine .. I was very excited to take my car to cars and coffee the next day but would soon find out that wasnt going to happen .
Once I got to the car wash I put the car in the hands of the wash and let them pull it around to go through the building washing machine thingy (you know what I'm talking about ) and when they went to pull it further the car wouldnt start ..
First thought is that the plugs I used were too cold .. they were NGK Racing plugs and I want to say they were 7's but I really dont remember .. me and my buddy now stuck together walked down south Lamar some 2.5-3 miles to get new spark plugs .. convinced the car wasn't getting enough spark . Came back, changed them, nothing .
Now we've got a shit show on our hands as tons of rich hipsters stand there staring at me and my pal struggling with this damn classic car . As I sit there working on my car (checking wiring issues) a guy walks up and he says "I'll pull my car over and give you a jump man one sec ... " as if I needed my car to be jumped SMH I started the process of elimination .. Engines need a few things to run like 1) Compression 2) Fuel 3) Spark and so on .. It was getting spark before and after I changed the spark plugs and took the long walk .. For some reason the car wasn't getting any fuel . I followed wires back to a relay that sounded like it had something inside of it bouncing around . Decided this has got to be the part and started to look for a replacement .. 2 weeks later after sending the part to Arizona to be rebuilt and sent back I put it in the car and get NOTHING ! jackshit ! NODDA! not a damn thing after 2 weeks with no fucking racecar .
Saturday I got pissed and just hot wired the fuel pump on in a last ditch effort to make it out to Harris Hill Raceway .. The car started right up when I did this and when I gave it a cunt hair of gas it died and flooded the motor . I call Triple A (The best investment of all time when daily driving a classic car) and had the car towed to my house in south Austin after 2 weeks of sitting at the car was .
Side Note : What a delight it was to see Matt Ferra driving out there at Harris Hill Raceway on the newest episode of Tuned even in the rain .. still badass . ..We made it out to Harris Hill on Sunday and was able to catch the last hour of the 3 hour endurance race (3 hours 1 tank of gas . Whoever goes the farthest wins ) but not before getting "Dazed and Confused" at Top notch . This is the burger joint !!!error: Indecipherable SUB-paragraph formatting!!! character "hollers" at the girl with curly red hair and invites her to the party . Great burgers and on Saturday they have movie night with lots of classic cars.. Before we left this showed up ..
Back to the problems with this thing
I expect that the ECU has gone out and thats why the car died the second I touched the gas .. makes sense to me but after being stumped multiple times I'm starting to doubt my hypotheses so any insight on the problem would be very nice ! Any Austin Jalop/Oppo that thinks they could help let me know...
Now that you've read all that I need a trailer and a truck to tow my car to Fort Worth where my 5.3 liter V8 , T56 6 Speed Transmission , and NEW ECU are waiting ..
OPPONAUTS UNITE !

I had a Celica that would run like shit or not at all when it rained. Turned out water was getting into the distributor cap. It sounds like you might have other issues but the car wash causing it makes it worth looking into. Good luck with it.

cap and rotor burned, sparking the wrong plug at the wrong time?

I like to think so but it just couldnt be the cap and rotor hasnt been touched .. and it was running fine when I pulled it into the car wash .. even started up multiple times moving it forward a few feet .

They can get carbon tracks on the inside and cause all kinds of havoc, it's hard to see sometimes too. That Celica I had to change the cap and rotor once a year. It would run fine then all of a sudden have no power and barely run, then it would be just fine again, it was odd. Good luck with the Z hope you get her sorted out.

Please forgive my lack of knowledge about this engine, but does your distributor have points? I don't know when the auto industry phased those stupid things out so like I said, forgive me if I sound like an idiot.

kinda shooting in the dark here, but I know lots of Zs end up with shit clogging the fuel lines. You'll end up spontaneously not getting enough fuel. Could you: have gotten some stuff in the way, car won't start (ECU registers lean, tries to richen mixture), stuff gets rustled around by fuel pump, ECU mixture is now to rich so it floods?

Well when I hot wired the fuel pump it started flowing fluid like a 15 year old at a beiber concert .

Gotcha.
ECUs are pretty hard things to break, unless it's been sitting in a puddle of water.
Have you confirmed that it's a fuelling problem? If not, pull some injectors and see if they're spraying.
Another thing to consider is any sensors that are attached to the engine. My dad's 156 stopped starting at one point, and that turned out to be a crankshaft position sensor that was on its way out. It was panicking as it thought the crank was in the wrong position and wouldn't start.

Hmm. Faulty injector connections? I don't remember much of em since mine's carbed, but I think you can measure the resistances across the injectors to check that they're ok.
More Power!!and also some brakes.

I am in Austin, have a truck but no trailer. Also, my truck is 48 years old and not sure it would make that trip towing anything even though it made the trip from Dallas to Austin under its own power.

I've got my fuel hard wired to pump fuel into the engine .. no unless its something incredible simple and I just cant find it right in front of my face (which could be the case) I am out of ideas ..

Looks like a typical injector problem... Pull them out, clean them and make sure the fuel line is not blocked by fuel tank depot...
The exact same problem you describe happened to my old mustang I used to have... Injectors were at fault. It would sometimes start, most of the time it would not and when it did, it dies as soon as I touched the gas
