I just installed Dual timming chain Sat -Sun on my 85 22r EFI

I'm at 8* Cold
Got it running and started Driving home, and 4 blocks later it Died when slowing down for traffic at 20 mph.

waited 10 minutes and it started again, Drove on Freeway 65mph, runs great, Smooth, 15 minutes on highway.

Then near home and it died when slowing down t o stop at light.

Towed it home, Engine starts, runs smooth at 1000RPM idle, then warms up and dies.

I'm at 8* with Te jumpered. Cold

The Haynes manuel does not say, it says put on 0 @ TDC

Roger 4crawler.com says 5*

Some people say 13* cold

Some people say 8*

read somewhere put at 16*


Engine sometimes runs well and can drive , when slow down it dies.

Engine sometimes starts , idle then dies

Came home from work Monday , engine Starts then dies in 2 seconds
try again push gas and it just dies

The Timming Has to be OFF ????!!!!???

LC engineering says I have Fuel Pressure problem

I have Fuel flowing and NEw Fuel Filter !

How do you test Fuel Regulator ????

Nix_Toy

it's 5*BTDC, Warm

kyle_22r

with the jumper in place, and engine warm, you want to set your timing to 5*BTDC as a starting point. with the jumper removed, it should read about 12*BTDC.

toy4crawlin

thanks But if you just put engine back together the Engine is cold .

Does not make sense to run engine on bad timing until engine has warmed up

toy4crawlin

You get a False reading if you remove the Jumper


thanks all but now the Engine no longer runs

Just starts and Dies, Just starts and Dies, Just starts and Dies, Just starts and Dies, Just starts and Dies, Just starts and Dies,

PLEASE HELP

Valve job last year, Could they all of a sudden be to Tight ?

Is this igniter Related ?

Is it a bad Fuel Dampner?

Bad TPS

Bad AFM

My jacobs setup would do that, I always carried the stock wire to bypass the jacobs. I went thru 4 jacobs units and gave up (all were warrenty)....

Might be too much timing...but should still run...

recheck all you connections, might be something simple...

toy4crawlin

IT"S ALL FIXED.

RUNS GREAT !!


I was poken and pulling on all wires and for some reason ( I did not do)

The resistor Yellow Plug on passenger fender was NOT SNAPPED IN


I would post picture , but the Kb and size is to small
