Re: coil and other codes, 99 euro running rough and wont start sometimes.


 

Hi Todd,

If the starter doesn't go when you turn the key, that's most likely a
totally different problem than if the starter goes but the motor
doesn't start.

"No starter" is usually a relatively simple thing to figure out...
- not in Park or Neutral (I have seen this more times than you'd think!)
- weak battery (try a boost start?)
- poor (dirty) battery connections
- poor connections in small wire to solenoid
- bad ignition switch
- bad neutral safety switch (try starting in Neutral)
- bad starter or starter solenoid

Turn the headlights on... they should be turned off automatically when
you turn the key to start. If not, that suggests something in the key
switch or related wiring.

I have sometimes connected 12v from the battery to the small wire on
the starter solenoid. If it cranks, starter is OK, problem is
somewhere in the circuit from the battery to the key to the starter
solenoid.

Can't comment on the CEL and coil... I have the old 5 cyl motor which
is very different.

for the past few months car has been running rough when ideling. and a
few times over the winter it would do it only after a hard rain. last
week it wouldnt start, new battery, just wouldnt turn over. after some
rest it started took it to VW. had codes PO400 EGR bad they think that
is the solenoid. PO300 and PO302 misfires. needs coil plugs and wires.
I am going to do the coil first as I have had that code in the past,
arcing. just dont have money to do all. also possiable speed sensor?
The car always started for them. but has done it on me 2 more times
while waiting for coil.

Question: Does the primary problem sound like it would be the
coil/plugs. Or would You try something else first. Check engine light
has come on and off for 6+ months, started only after rain then off
when dry now on after this problem 90% of time.....thanks for your
help....todd R.I. via Oregon
