I would check the compression first. Without compression it won't fire. I should be at around 160psi per cylinder. If any are below or varies 10psi per cylinder, then the engine needs to be rebuilt.

98 chrysler sebring sat w/out running for 4 years cranks but wont start any suggestions as to what is the problem or what to do to make it start


I would have probably given it a total tune-up, first, checked all the fluids. New antifreeze. Changed the oil and filter. Drained the gas tank, used fresh gas. Pulled the spark plugs and belt, put a drop or two of oil in each cylinder, then turned the crank by hand before trying the starter motor.
Then, if it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Any applicable trouble codes?

1992 geo storm replaced distributer have fire out of coil wire but no fire spark plug wire module in distributer checks out


storm is an ISUZU
and had 3engines,which one? below is off wiki on storm.
1.6 L SOHC 4XE1 I4
1.6 L DOHC 4XE1 I4
1.8 L DOHC 4XF1 I4


coil makes 50,000 volts (even 1kv makes fire, but is too weak spark
spark plugs dead , right? all 4 right?
ever do a 60k mile tune up ? if not why not, it gets new spark parts then..
also, if the cam timing is off. the dizzy sparks between towers
make the distributor useless, it cant distribute spark.
so the first tests are .
static ignition timing. (yes, a tool, called a timing light for $20)
if timing is good the the wires HV are bad.
if timing is bad, bingo..... this is the first test on any motor.
if the timing belt or chain on any SOHC or DOHC engine slips
the dizzy will be way to h3ll off.
learn to use a timing light, and works 100% cranking.

look at that distributor cap (replace it)
see the coil wire , center, that is at 50kv spark.
and see that rotor, if the spark is good at the cap pins 1 to 4
then the dizzy is timed.
if the spark dont reach the spark plugs that means
the wire are bad or the spark plugs are shorted, or both.
its that simple. using a real spark testing tools tells you the KV.
kv = kilovolts. the best tools $5 bucks have and adjustable gap
this car is not 100kv, like newer cars and must be set (tool) to 50kv or tad less to show full powerful spark.

take care not to get shocked, keep hands off the parts
as friend cranks (or remote start button tool)

1999 Dodge Intrepid 2.7L Replaced starter,


Here is a pic of a schrader valve. They all look about the same.3.jpg
If there isn't much pressure, cycle the ignition without turning the engine over and try again. If it is still weak, you may need a new fuel filter. If it is strong, you may have dirty or clogged fuel injectors.

It may be spark, but I'm inclined to think it is fuel related.

Good luck, and keep us in the loop!

1997 Chevrolet 1500 no start


is the fuel spraying into the cylinders? pull a plug and see if they have fuel on them.....If not you have a problem at the injectors if there is pressure on the rails. If fuel is present you aren't firing strong enough to ignite the fuel. pull a plug and put the wire on it and touch it to a ground and check to see if it is a good blue spark or a weak white or yellow spark...If no spark check for dead plugs or distributor module,

NO SPARK PUT A NEW COIL ON DID NOT FIX TOOK IT TO A GSRAGE SAID IT NEEDED A CRANK SENSOR CAM SENSOR WIRES PLUGS DIST CAP AND ROTER RAN ONE DAY NOW THEY SAID A HOLE DISTRIBUTER AND A TIMEING BELT.I REALLY...


If you are sure they said, a distributer cap a roter and a distributer, there is a problem! Because on a 1998
plymouth, there is no distributer or cap or roter.
Your cam sensor along with the crank sensor-temp sensor and a few other sensors, send a signal to the
powertrain control module, that sends a signal to the
coil pack(that you said was replaced) that fires the
spark plug. I would hold off from having any further
work done there, until you can check out what they
say they have already done. Ask if you can have the
old parts they replaced so far. You will want to have
an OBDII scan test done, to see what codes come up. It should have one of the first tests they did.
If I have read your post correctly, have them write an
estimate for what they will replace next. This info. is
based on the car being a 1998 plymouth and not a
1988 I would not wan't to acuse somone of anything
based on a typo. Hope this helps. Good luck.

NO FIRE


hi there, you need to make sure all wires to spark plugs are tight and very snug, you will also need to check the distributer cap to make sure no burns are on it, and make sure the plugs are in proper firing positions, the spark rotation might be out of sequence.....also make sure spark plugs are clean of all oil, and dirt, firing pin in distributer cap might be bad.....hope this helps....shia

1991 Honda Civic STILL won't start


if your not getting spark then your coil is the mostlikely cause it's obviously not a timing issue since you stated that the rotor is spinning. if the spark plugs are bad then replace them too . to be sure that your getting spark to all cylinders test each of the spark plugs after replacing the coil. just to besure it's not starving for fuel as well spray a little ether in the breather if it fires off right away that means the even though your fuel pump works it may not have a high enough pressure. let me know the results

Won't start.


need to ask some questions. does it have spark at the plugs? how many miles on it? does the engine crank with different sound than normal? if it has spark, spray couple good blasts of ether inside air snorkel and see if it fires. has the timing belt been serviced? has the engine lite been on?

No power to fuel pump, relay is good, engine cranks over but won't start.


You need to follow a detailed troubleshooting procedure in a repair manual.
Check for spark plug fire during cranking after it dies.
No spark = ignition problem= computer will not fire injectors, and possibly cut out pump also.
Good spark = pump wonky, or power to pump system.
Also, other quick tests... when the thing dies, and then you crank,
1) Thump the fuel pump in the tank, if you can. A bad fuel pump might start up again.
2) Shoot some ether carb cleaner in the TB. If it only fires off the ether, the ignition system is no longer suspect.
