Archived from groups: alt>trucks>ford (more info?)

I took the beast in for its i-annual service and reported to the service
guy that I was concerned with the performance on startup. It suddenly
takes longer to start than before - it used to take maybe half a
rotation of the crankshaft and now it takes maybe 3-5 seconds of
cranking.
He did a service, change d the spark plugs and the air filter, and told
me that if this didn't help I should consider getting the fuel injectors
flushed out.
I have never heard of this before. What is it? Why do it?
The thing has maybe 130 000 km (or for the Americans, about 80 000
miles) and I have never had problems that indicated a bad tank of gas.

Burning fuel leaves behind some residue. This can build up around the
nozzles of the injectors and either restrict flow or change the spray
pattern enough to effect performance. They temporarily disable the fuel
supply from the tank and run the motor off a cleaning solution which removes
the residue.

Thanks for this. I don't think it is the fuel quality issue because the
problem was there through more than one tank of gas, and they were from
different dealers - some international names and some only Provincial.
The Alternator tip is worthy of keeping for MY particular observations.
I'll just hang onto this one.

I recently had some problems with my Dodge Custom Van, and the mechanic
suggested a cleanout of the injectors, inner plenum, etc.
I was a little sceptical at first, but let him run with it.
He has an optical fiber tool that he can use to see inside the induction
system and
can even get a look at the backside of the valves. Mine were filthy, heavy
buildup
of unburned gasoline remnants.
In this case, the treatment completely solved the idle and dying problems. >> Stay informed about: Pumping out fuel injectors - '99 Ranger? |

My '92 Explorer has been taking a lot more cranking to start but if I turn
the key on and off and let the fuel pump cycle a few times it usually starts
right up. I thought perhaps the check valve in the fuel pump was letting
the fuel back into the tank but now, after reading all this, I'm not so
sure. >> Stay informed about: Pumping out fuel injectors - '99 Ranger? |
