Cant get 1983 isuzu pup to run proper after tuneup


list parts changed,?????????????????
a real tune up is many parts.
and is this a CARB car, sure.
and CARBS are Very difficult to run right this old, very very hard.
finding parts for an Isuzu in USA or carb kits, is insane hard.
id sell the car, while still can.
buy a Toy. (easy to fix, infinite parts)

My 93 geo storm will run for a couple seconds with engine start then quit, is there an anti theft switch under dash.??


STORM = ISUZU.
Isuzu Impulse,
a very rare car. 70k made, 3k in Canada.
they hand 2 Isuzu engines, DOHC, 1.6 and 1.8L
is car a daily driver, when did it last run right?
is fuel fresh....
ever do a tuneup on it? spark parts, and filters.
can you keep engine running with a fast right foot, (a key answer)
the stock car drawings ,show no IMMO , nor any alarm.
but the operator guide can be had,......

the real question is why it stalls.
you crank it
it starts and stalls.
we do simple test to find this,
this car has very simple EFI so. is easy.
1: engine compression above 150PSI x4.
2: 12vdc running, if the voltage falls below 11vdc, running fix that first.
3: spark spark good at all cylinders, test it, get a tune up.
4: fueling, too much or too little and it stalls.
the fueling tests are a long story and ill wait till you get this far.

86 Toyota Celica starts, runs for a second, then stalls out... any ideas?


try to open the air filter and pour a little bit of petrol inside carb, bottle cap size... if its runs, then your carb need to service, the car might not starts for quite sometimes i guess.
