vehicle is stalling or acting as it has no power. doesnt happen

This answer was rated:

The vehicle is stalling or acting as it has no power. doesn't happen all the time. feel it when accelearting. Acts like clogged fuel filter type problem. I have changed the external fuel filter. again does not do this all the time. Ran it about 15 minutes did it a couple of times and then stopped doing it.

Billy :

Hello and welcome to JA!!!

Billy :

I'm Billy and i will help you with your question.

Billy :

Since the stalling does not happen all the time, then you are right the fuel system is the first to check.

JACUSTOMER-k9on6rql- :

Thanks

Billy :

But i need you to check the

Billy :

for clogged lines, and i need you to check the pressure regulator....

Billy :

the best way to check this problem is by having a fuel pressure gauge attached to fuel rail while driving the vehicle.

Billy :

And when the engine stalls you check for pressure changes. If the pressure is well during the stall, then it is something else than the fuel system (although i doubt it).

Billy :

I suggest you do the following:

Billy :

put injector and fuel system cleaner in tank.

Billy :

clean fuel lines to and from tank using compressed air

JACUSTOMER-k9on6rql- :

the vehicle has 160,000 miles fyi

Billy :

and revv the car a few times after cleaning your system.

JACUSTOMER-k9on6rql- :

Will the injector cleaner take some time to show any effects?

Billy :

if you put the injector cleaner in an almost empty tank (has less than 4 5 gallons) and you drive the vehicle and revv it up a little bit, the cleaner should give results after about a 30 min ride

Billy :

While you're checking, i suggest you take a look at the air cleaner and the spark plugs.

JACUSTOMER-k9on6rql- :

Air cleaner is clean. plugs will have to check.

Billy :

the symptoms you describe don't point to a spark plug fault, but it doesn't hurt to check...

JACUSTOMER-k9on6rql- :

ok will try the cleaner. If problem persists, does the chiltons manual show where to hook up a pressure gage

Billy :

yes

Billy :

it's on the end of the fuel rail

Billy :

the fuel rail is attached to the injectors

JACUSTOMER-k9on6rql- :

ok

JACUSTOMER-k9on6rql- :

any other suggestions? I will go and try the cleaner

Billy :

no....i think after trying the cleaner, you only have to conduct the pressure test, which gives you a definitive answer on wether it's the fuel system or not.....(i still think that the fuel system is the culprit)

JACUSTOMER-k9on6rql- :

so if the cleaner doesn't do it and I do have a pressure problem what is the next likely prolbem

Billy :

pressure regulator

JACUSTOMER-k9on6rql- :

I take it that is replaceable (haven't looked) or adjsutable

Billy :

replaceable.....not adjustable

JACUSTOMER-k9on6rql- :

difficult? ex[ensive, somehting a dyi'r could do in the garage successfully?

Billy :

not expensive at all.....

Billy :

a diy'er could change it easily......especially with a chilton service manual at hand.......

Billy :

wouldn't take more than an hour

JACUSTOMER-k9on6rql- :
