I was leaving work the other day and I made it a mile down the road and
my car just dies. It would start back up for 30 seconds and then shut
off again. When I tried to immediately restart it, it would chug a bit
but not turn over.
I towed it home and my uncle replaced the PCV Valve on it and it seemed
to run fine for a bit of driving around town and then it died again.
It continues to do the same thing, It starts up for 20-30 seconds and
then die again.
Does anyone know what the problem could be? I was thinking Fuel pump
I would first pull any stored trouble codes and run KOEO (and, if possible
KOER) on-demand diagnostics. If this vehicle has a check-engine light, the
only tool you need is a paper clip. Google for EECIV diagnostics to find out
Post here what you found -- there may be a good clue there...
If he has a simple fuel delivery problem, and he most likely does, pulling
the codes will present a ton of red herrings. You're likely to have several
codes just because the thing is stalling out. Testing a whole bunch of
circuits or sensors would waste a lot of time, imho.
I'm not saying you're wrong, but, personally, I'd rule out fuel pressure
problems first. After all, we're dealing with EEC-IV; it's not high tech...
Indeed, but if, as the OP mentioned, the engine re-starts after stalling,
it's unlikely to be the infamous TFI module failure. I would hate to tell
someone to go through the hassle and expense of replacing it, just to find
out that it won't help.
Measuring fuel pressure is, of course, the right thing to do -- if they have
a gauge. But something abuot the story of uncle replacing the PCV valve
first is telling me that they don't have one (I mean a gauge, not a PCV
valve...) And any amateurish method of checking for fuel delivery is
dangerous, especially around a hot engine.
I would still advise sticking that paper clip and reading the codes. There
is nothing to lose, and both the OP and his/her uncle may gain some useful
knowledge in the process.
In the TFI failures of the 80's the module did fail totally. there have
been other instances on here regarding 90 series units where the symptoms
fit (heat related, internal short or open), restarts then stops as unit
As CJB said.. the codes thrown MIGHT be superfluous and from same source.
But it's worth trying, relevent codes would shown 'Lean' condition.
I suggest the poster listen for the fuel pump. If he hears it running
on 'key-on' but car wont start till engine cools, I doubt that's it.
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
What motor? 3.8? losing any water?
If it is a 3.8 and your smelling a sweet smell when it happens,
your head gasket may be leaking.
If you have not done any maintenance, now is the time.
Replace fuel filter, spark plugs & wires. Check all small vacuum hoses
for deterioration and replace as needed. Look close there are many and
some are hidden. Clean battery cables and retorque all connections.
Others have mentioned the TFI module. Both of mine that died went dead.
but that's not saying intermittent is not possible. Its on the base of
the distributor on some models and it takes a special thin wall socket
tool to get the mount screws out. Make sure you put the thermal grease
on when you change it (if you do).
