Low fuel pressure ? Commonly caused by failing fuel pump...
Water in gas?
Plugged fuel filter?
Ignition system failure? Timing chain jumped?
Lots of possiblities, so you need to eliminate them, one at the time.
Dont just start replacing crap, willynilly.
How much fuel pressure did you register?
I show it as having a timing chain, and an internal balance shaft geared
to the camshaft. Maybe I am off by a couple of years.
If your spark does not come exactly when the cylinder has fuel
charge and compression, it will run roughy or not at all.
old car.whats the motor.what's the mileage.if the fuel pump has never
been replaced it seems a prime suspect.squirt gas directly in air
intake and see if it runs.if no i would suspect ignition modual or
coil.if 3800 could also be timming chain.(high mileage)any recent work
to motor or car..more details mean a better diagnosis.
i tried spraying carb cleaner into intake...didnt help..it does have
130,000 miles on engine..no recent work done on it and someone said check
the ..ill call it harmonic balancer cause they have a rubber insert and
have a sensor that ...well i forgot but i did check the rubber insert
thing and seems ok..im still lost
There is sensor in the timing chain cover, which is actuated by a magnet
to the gear. It is not uncommon for that magnet to fall off, and a code
will be set.
It does not stop the engine from running, in my experience.
