89 suki sidekick keeps dying-flooded?

[bruski]

flash code, (just like old GM) 12s is good. Gm has the same deal, even back to mid 80s... its not new, not at all, OBD1 is all like this,
even the first EFI vettes had this... same deal. GM did this way before the 1988 smog law was written, (jumping the gun was super smart by them)!!! (Cadillac Seville TBI 1979, 38 years of EFI)
until 1996. OBD2 happened, (youd be getting misfire codes)
make sure the dome fuse is good or the ECU memory goes dead, causing error driving , to be lost, when you stop and key
off, dome fuse good, is cure.
then drive, and make sure CEL stay off.
you said
heck eng light only came on or flashed when letting off the gas, (TOP WARNING HERE)
that means (dome fuse good) drive with the DIAG jumper inserted, (harmless this is ) and then the real error as you drive.

most the DTC that set , cause limphome, mode
and will loose power,go rich as a pig and blacken the spark plugs,

is this your diag fuse?

if yes then that is it.
if no its next to battery

the key things on this car (beside a full tuneup)
1: CRANK Front bolt, 17mm socket at 94/ft/lbs never less. no damage to snout and timed correctly the belt.
2: fuel pressure at spec.
3: distrib ok, no misfiring, no bad ignitor there.
4: fuel pressure at spec, cranking and running, fuel pressure is zero or falling keyon only, unlike 1991 and newer.
5: stuck in limphome (limpin or failsafe) *(most DTC error the)
6: ECU lost syndrome, mean ECU can not get fuel rate correct (its dumber then) top reason #1 above.
7: EGR stuck open , stall, only WOT works.
8: its not vacuum air leaks at all.
(

the dome fuse is right next to the HL fuse, head lamps

is this your box.? its a shame ever car the PO lost it, a dirty shame, forcing wire color validations...

you said it stall.
down hill to a stop
but can you prevent with fast right foot, (easy, hard, impossible) we need this KEY FACT.
keep the diag, jumper in place until car is fixed. and WIN.

Yes, can pervent stall if I keep rpms up.
Still reading 12---did read 14 once, that.s all.
