Question Details Asked:Oct 07, 2010 - 09:24 AMStatus:Closed

puukapupastor	I need help starting my 1994 Isuzu Trooper LS V6, doc. I think it is a fuel issue. 1) NAPA auto doesn't show my Trooper having a "CAMSHAFT POSITION SENSOR". They did sell me a "CRANKSHAFT POSITION SENSOR" however. My trooper is a 94 - LS, dual overhead cam, 24 valves, MPFI 2) Where are the sensors located? My Chilton manual doesn't have the best pictures. 3) How would I test or now if the injectors need cleaning? Thank you. I really appreciate the help. BJ

Well you can buy a simple tool called a NOID LIGHT and this tests whether the injectors are getting an electric impulse or not.

But first of all, by all means take out the spark plugs and clean or replace them.

Then you must CHECK FOR SPARK---you can buy a simple tool called a Spark Checker
