2002 Isuzu trooper wont start

which engine, ill toss coin, land on v6
check fuses first.
wont crank? that grrrrr grrrrr grrrrr sound
jumper cable start it yet, why not?
or put in a known good charged car battery?
or using any battery charger charge yours?
or buy a new battery, (if rich)

if it cranks and wont start?
check spark x6 (scan it yet?)
if sparks ok try test fuel!
if test fuel fails 100% see bad belt below.

EVER REPLACE THE CAM BELT?
if not and over 60k on the last one
the belt is doomed, living on borrowed time.
got the V6?

Try disconnecting a battery cable. Reconnect 5 min later. This resets the ECM. These vehicles are a real continuing problem when they get old. I had a 1990 Trooper II and finally junked it last year.

test your m.a.f. semsor

Great.

check the fuel line pressure it should read 55lbs ,on the fuel injector rail is a tyre valve looking thing with a plastic cap ,connect a pressure gauge to this and see what you get

yes sir mostly its a fuel pump regulator problem .
check the fuel pump pressure to make sure it is the pump regulator that controls the amount of pump pressure or change the whole pump would be better have a good day sir

car ran out of gas an now it wont start is fuel injected 1994 isuzu trooper dhoc

It actually could be a number of things. I need to ask you more questions to narrow my prognosis down. You mentioned the weather being cold, lately. How cold? Freezing?When was your last tune up and do you eventually get the car started after trying for a while? If you do how does it run?

bad generator

i put a new stereo in my 1998 isuzu trooper now the anti theft wont let car start what do i do
