finding the true path can be hard. very hard. but my add fuel trick does work. takes about 1hr.
see top hose here< left top, inline with Electronic?
that is EVAP
pull it at the plenum there.

make sure the nipple sucks air running, ok good.
now connect a hose to that nipple, (just buy some vacuum line) say 12feet.
run to cab.
then off the propane cone,
connect hose to the propane, neck pipe.
here is the pro. setup by OTC company ,its overkill

all you need is any propane (small) torch. and off the nozzle cone,.
this works

we do the same thing to test, the EFI system.
we add propane and watch fuel trim with the obd2 scan tool
or we add air. (rich for propane , lean for air)
if the engine bobbles. (hiccups)
and the lamps on car don't dim, and the CIG lighter port? drop>? (use a voltmeter here) dont drop.
then its spark or fuel.
here is a nice walfart tool that lets you watch the CIG power bus.

the wipers run off igntion so of wipers die, at the hiccup , bingo. This is the best power feed to monitor. IGcoil-turn-back-wiper-wash , all run off black-white IGN feed.
keep in mind the injectors have their own DC feed, line FI, black- red. and that big connector front bottom of plenum can get bad , its all injectors there.
even try removing all keys from key ring and use just 1 key to off load the poor ignition switch, and its failings.....
the propane test can tell you ,
1: ECU is not losing DC power. if the power recovers with propane , the spark is good (2 facts), and injections are wrong. but the injectors have their own power feed bus.
2: if the propane does nothing ,it's spark. (or DC power to it) The Dizzy uses IGcoil power.
just knowing this allows us to work just that path. and a final cause.
if IG-coil feed drops, the gauges drop , too., one more clue,
Im very DC power centric due to all the many connectors on the car that love to rust. (corrode)
DC is here (all)

let me make a list. At hiccups?
and my table of grounds posted above are all good. clean and tight grounds.(the critical grounds) even a loose starter ground wire.... bad news.
i have a data-logging volt meter that allows me to drive and log and monitor anything i want. It find the hard cases.

Quote:radio don't drop, out, wipers keep going, head lights dont dim, the cluster gauges do not drop or glitch (they are so slow and glitching is masked, mostly)Gorkys dissy conn, checks
monitoring the CIG port shows, no glitching.
front injector harness is not bad. here. see FI? NO DAMAGE THERE !!!

propane corrects it.?
propane does not.?
