Timing, stumble

[Andreas]

I was kinda dissapointed tonight when I was about to take it for a test drive.
I sputtered really bad and almost died when driving it.
The truck fires up good. Was about to set the timing right. With the tan wire connected it was past the 8* mark, more like 12* or something. Pulled the tan wire and truck dies.
Retarded the timing so it was about 8* with the tan wire connected (like my friends TY) Idles good and then pulled the tan wire. Truck dies every time.

Got new MSD dist. Stock dist was just worn to pieces.

Tried diffrent fuel preassure. It should be around 38-43 psi with vac line off, right?

I've been reading posts about timing for a while now.

TDC #1 I know for sure was right with the mark on the damper, checked that when I put the heads back on. Cam chain was right too when I put it on.

BUT I've rotated the motor when I search for fault when the fuel preassure wasn't holding (diffrent tread here). It could be that the damper slipped, but would it fire up then?

Something isn't right for sure.

Re: Timing, stumble

i check ditributer again maybe your one tooth off

Re: Timing, stumble

It's middle of the night here and i can't figure out the "one tooth" thing. I've got TDC #1 and the rotor is right on the #1 on the cap.

Re: Timing, stumble

Within reason there is really no such thing as "one tooth off." All you have to do is rotate the dist to compensate. Eventually it'll hit something though, and it can make it more difficult to reach the bolt. If the dampener is not slipped and the timing is set with the tan wire disconnected then it's something else.

try a stock dist.

Yes the cables to the ign module isnt that long so I guess thats the thing that limits the dist rotaion (thats no issue in this case thou). But the rotor is on the #1 plug wire when #1 is TDC.


Branden:

Unfortunally I got no possibillity to try with stock dist


I read somewhere that simmilliar problem occured when turbo started to seize.

Gone do CAD-monkey work for some hours and then back to the garage.

Re: Timing, stumble

i haven't read in your post that you put your timing on 0 with the tan wire disconnected.

i haven't read in your post that you put your timing on 0 with the tan wire disconnected.

Thats correct, because the truck dies when I disconnect the tan wire.

than your timing is to much off, have somebody starting the truck while you rotate the dist a bit, untill it does want to start. with the wire disconnected
before you do that, check if you don't have any crossed wires.

Re: Timing, stumble

Gone try that.

With crossed wires you mean the plug wires right?

yes, that you didn't mix them up

Re: Timing, stumble

yes, that you didn't mix them up

I actully did that a couple years ago.
Checking that to but I'm pretty sure thats not the case.

But every input for me is well needed help

i mean that you didn't swap 3 with 5 or 1 with 6 etc.

Re: Timing, stumble

Got my truck running with correct timing, but with some stumbles sometimes.

Still dont got my datamaster auth.code so I can't see whats happening. Just running 8psi for now. Oh maaaaan with just 8psi its a rocket compared to my wintercar WV Jetta haha

But I got some other woorries. Se tranny section.
