Help! Truck broke down

[badmix]

Just got towed home. The problem is consistent.

Truck starts fine, idles, and then 60 seconds later just dies, like ignition turned off . And then I can start it right back up and repeat.

Truck had holley street avenger rebuilt 6-8 months ago

New HEI distributor installed with new plugs and wires.

Pulled fuel filter, little but of debris but not enuff to restrict flow, pulled carb filter and ran without it, same issue.

Fuel pressure bounces between 6-9, sometimes from 3-9

There is no sputter, or miss prior to dying / shutting off.

I'm stumped, have no idea where to begin

I would be looking at the coil or module.

Maybe tell us what year your truck is and what it is? I’m assuming a carbed 350? Could be the dist pickup coil. 5-7 psi for a carb, 3 psi is getting pretty low

1984 K5 , 305 180k odo, 700r.

Distributor is only 6-8 months old,,not saying they cant crap,out.

I was going to put old coil and cap in an I have a spare fuel pump as well. It doesn't seem to be a fuel issue but I jus don't know. It seems electrical the way it jus stops running.

What kind of dist? The cheap ones don’t last very long

 

[Wes Harden]

yeah the billet Chinese dists are junk.

if is quits like someone turn the key off, it's normally electrical, coughing wheezing dying is fuel

It's An Accel GM HEI performance distributor.

Put the old cap and coil on it,,no change

 

[Wes Harden]

it'll be the pick up coil, since it starts right up, after dying. The backing plate moving is causing an open in the pick up coil. Ohm check the coil while moving the wires and cycling the advance plate.

Trying to put old distributor back in and now can't get the oil pump rod to catch bottom of dizzy.

I thought I had dizzy issue before, ended up being bent push rod. So I believe it's still good. Now can't get it on, I marked firewall where rotor was pointing when I took out. When I install other one, it's one spot off, pointed at next plug.

 

[Wes Harden]

use a long screw driver to turn the oil pump drive rod slot counter clock wise a smidge

 

[badmix]

FIXED!!

Replaced dizzy with my old one,, works good. Gonna call Jeggs tomorrow to see about return/exchange on this accell as it is less then year old.,installed Sept
Last year

Did the screw driver trick, eventually got it

For future reference, dizzy placement is more about having the plug wires right and firing order right than where it sits relative to the engine. Glad to hear you got it though
