Engine light code 44 1994 GMC Sierra Pickup HD 5.7l, 4wd.

no year car told, no engine told and is a pure engine/EFI question.
a minute not 10second and dies,
the dash IMMO lamp must not be unhappy or the engine is immoblizeds in 1 to 10 seconds. most cars or dead totally others.
well , there are 50 causes or stalls on all engines
we do up to 20 test using 10 or more tools to find real cause. guessing 50 times , no shop does that .

can take the line and put in a can of gas it will run????????? HUH?
this means test fuel works? sprayed into the intake
and runs means it runs for 3seconds on test fueL and stalls/

we cant see your acts there, Impossible. too.

here is the order (pure physics Otto cycle gas engine) ASE rules( books/training)
engine must be good. (compressing tests pass and test fuel works.)
spark must be good. if is test fuel works and and runs for 3 second
is all a good sign
then last is fuel all above ok testing
fuel pressure must be at spec, no car told SO can not look that up.

sierra what is it and year.
Chevrolet C/K C1500 pickup or k = 4wd or ) what engine, lots of engine,
Chevrolet Silverado
Chevrolet Suburban
top fix any car engine learn what is under hood first
the RPO codes tell that. and VIN .
by year

Dec 15, 2007 - 30 posts - ‎22 authors please someone..i need help.i have 1992 gmc sonoma 4.3 6 cyl 2wd .... I have a 2001chevy s10 4.3 4wd auto, it runs good until it's warmed up, then once it's ... the gas pedal causes bouncing on the tachometer and loss of power. ... when driving at a steady speed if I try to accelerate the engine tries to die

Question, does this pickup blow black smoke on idle or at a stop sign. If so check your map sensor might be plugged up or unplugged or bad.

Not quite everything is fine.
Is the check engine light on ?
When you push on the gas pedal, does the engine speed change ?
Can you rev up the engine in park ?
What have you checked so far ?

It can be issue with fuel pressure,its low or the problem relates to faulty spark plugs.
There are few troubleshooting steps to confirm the problem.I suggest you few help links,with complete troubleshooting and solution for these types of issues.

This will help.

Thanks.

if engine idle good stall on acceleration either fuel filter clogged or fuel pump weak has low fuel pressure.

Ignore the light.

Please check the fuel line for leakage. If there are no leakages, verify that your fuel tank cover is well fixed.

Take care.

Check your engine codes for anything , you can get free info on the web or get a repair manual. it can be one or more problems until you narrow it down.
