the exploding thing is a l28et yeah i used to like it up until about 30 minutes ago.
oh god timing is my worst enemy.

hoov100 06-20-2009 03:07 PM

BUAHAHAHAHAHAHAHAHA!!!!!

LMFAO....

your response is funniest thing i have heard all week.

lmfao......

i recommend one of those craftsmen adjustable timing lights, there easy to use, are fairly accurate and are under $100. (i think it was $65?)

lol, also make sure you have the correct wires on the correct plugs.

NismoPick 06-20-2009 03:28 PM

Good shat... Take no offense tremendousti, but your long and drawn out swap is one of the funniest things evaaarrr!!! :D

Seriously though, have you been following the swap write-ups and checking in the Haynes manual as you go? This swap shouldn't be so hard...

yeah i can rent one from kragen but can i check the timing without the sparks plugged in? just cranking it with the starter? i really dont want to take apart the head and set TDC and start from square one that means new head bolts, new gaskets...

yeah glad i could amuse you. it sucks because I have had to go to college and move from two different houses in the past 10 months and im as organized as much as obama's stimulus plan is effective

Dude... How do you not have a timing gun!!!

#1: Make sure all spark plug wires are in the correct firing order.
#2: Make sure you have the distributor installed correctly (hard to screw up on the notched turbo dizzy... but as this swap progresses, I feel the need to mention it).
-A: Line up the crank pulley to 0 (TDC)
-B: Remove dizzy cap & look @ rotor. It should be pointing straight forward (directly under #1 spark plug wire port).
#3: Make sure there is proper fuel to the injectors


arg... lets go to that point... no need to complicate things.

EDIT.... did you take care of all those vacuum leaks on your intake mani?

hoov100 06-20-2009 03:43 PM

alright, pull the coil wire, then pull the number one spark plug, with the 1'st cyl. on its compression stroke, put the piston at TDC. Then take off the cap and make sure the rotor is pointing at the number one in the picture below.

no go yet, but its not blowing up so in my book that's progress. :023:

hoov100 06-20-2009 06:43 PM

engines need three things to run= air, fuel and spark, make sure your getting spark, then fuel and if your getting both, i would start looking at timing.



(and what does your sig mean by 71 l28et parts car?)

What are you doing to engage the ignition? Looks like you are connecting two wires when you reach down??? Why are we doing this half assed?

Get in the car and give it some gas while cranking........

snwbrderphat540 06-22-2009 11:09 AM

whats the ECU light doing when you A) turn on the ignition then whats it do when you B) start crnking then whats it do when you C) stop cranking but leave the key in the ON position right after.



and good job telling your woman to shut up ;)

snwbrderphat540 06-22-2009 11:12 AM

also get you own LED from radio shack you can use it to see if the injectors are firing. and did you or anyone every remove the oil pump? cause that can make timing a night mare! since you'd have to re-do it...

i'm using a key, how do YOU turn your car on? It's just dangling from the column so its easy to reach.

Okay so here's my timing

with the rotor at close to 1 it looks like this:

I took the gas tank out today and cleaned it off and sloshed out the old gasoline with new gas and put it back on so my gas situation is good:s-chainsaw:.

thetremendousti, i dunno if you've noticed yet, but there is a squirrel living in the back of your hat. May wanna take care of that before it starts breeding.:s-chainsaw::biggrin::biggrin:

thetremendousti 06-23-2009 06:51 PM

Npick - yeah i gave it gas when i kept trying to start it, it still wouldn't i'm not retarded, just slow at learning :102:
matt - yeah the ECU is fine and I put the oil pump in, dont worry I checked the notch and got the right tooth, actually I think i'm a tooth off now that I think about it but I'm working on that problem after this video uploads
but check it :)

i cleaned the spark plugs with a wire brush,re-went over all the electrical again, jumped the battery with a truck and messed with the dizzy but um it seems to be working. Also I put a half a gallon of gas in the tank I would a put more but I spilled the rest of it whoops.

hoov100 06-23-2009 07:03 PM

ok dude, your plug wires go as fallowing on the dizzy correct? 153624 ??

also make sure you have enough fuel pressure going to the fuel rail, as a stock ass old ass pump just aint gonna cut it.

BlueKitsune 06-23-2009 07:11 PM

Make sure you also dont have the wires backwards like #1 wire to #6 cylinder. Ive done that mistake before.

thetremendousti 06-23-2009 07:13 PM

yeah man 15 too young, 36 too old 24 just right :D i've centuple-checked them and
uh oh I have a '76 280z electric fuel pump, which puts out enough (~30 psi?) for the stock fuel rail and turbo injectors. I did take off the 4psi mechanical one so i'm half-okay i think.

BlueKitsune 06-23-2009 07:52 PM

Ok there's a good chunk of your problem, you need like 40PSI to run the injectors, on an N/A and I bet a turbo is more. I'd upgrade your fuel pump to the turbo one.

EDIT: Do I hear a knocking sound in the video?

oh shoot, well I just took the plugs out and they were wet, but I'm pretty sure that's cause i flooded it X( no bigs. Also, that's not a knock its just how the built-in-microphone on this laptop records a weird blup noise coming out of the exhaust.

BlueKitsune 06-23-2009 08:02 PM

Ah ok, I was thinking that something was lose cuz of the knock lol. Well good luck, keep us posted!

hoov100 06-23-2009 08:12 PM

try this real quick, advance the distributor until it stop, then back off like 1/8'th of an inch. if it holds an idle like that then your dizzy is more then likely a tooth off.
