1988 Buick Century stalls


Hi Deb, when it stops an won't start pull two spark plug wires off the same coil an crank it over an see if it has spark ! If it doesn't have spark you could have a bad crankshaft position sensor or ignition control module . If you have spark take the air cleaner box off or the flexible rubber hose from the air cleaner box to the engine off , just a couple of hose clamps . Spray some carburetor cleaner into the engine, because it's flammable ! IF you do this an it try's to start you could have a fuel pump problem or a bad fuel pump relay ! One more question , is your check engine light on ?

Engine dies at traffic light


Possible the previous owner had no concern for maintenance, never good to find that.
Scan for trouble codes as a first step-many parts stores will do engine scans for free. If codes are present attend to that first. Fuel pumps can fail in this way and not work again until cooled down. So you should have the fuel pressure tested. The best time to check it is when the engine stalls and won't restart. If pressure is low then (or anytime) then you would need a new pump. Pressure can be tested without running the car, just the ignition has to be on. Another test to do when it won't start is to check for spark on a plug wire. If no spark, suspect the crank position sensor. The PCM requires a signal from this sensor to know when to initiate spark. If sensor fails when hot, ignition spark won't occur. Could also be your ignition module, however. They also exhibit similar symptoms. And same for the coils-so check for spark on more than one plug wire.
Good idea to clean your throttle body. Use CRC intake cleaner spray and a toothbrush to clean old varnish and gum deposits around the throttle valve and inside the bore as far as you can reach. Also take off and clean the idle control valve or motor.
They get dirty and affect idle. You might want to have your throttle position sensor tested. Try unplugging the mass airflow sensor and see if car will start-if it does, that sensor may be at fault-when unplugged, the computer uses a default setting for measuring air flow into the intake.
Now is the time for a tune-up anyway, so buy new spark plugs and check your spark plug wires for brittleness, cracking, old age-if in doubt, check plug wire resistance or buy a new set of plug wires. Check or replace your air filter and fuel filter. How dirty is your oil? Clean oil always helps an engine run better.
I hope you find the problem, just keep at it. Especially check for spark and fuel when the car stalls and won't restart. And be sure to check for trouble codes-if there are any, it will probably point you in the right direction.
Good luck, Josh.

92 civic engine stalled while driving; fuel pump works; replaced all plugs seeing some oil on old ones. only one plug fires; is coil still working? or the distributor? haven't checked fuel...


Hi,
Check the ignition distributor cap and clean the electric contact points it might be already dirty.

if one has a spark that means your ignition coil is still okay. Remove the whole cap and check the inside part and clean it, use emery board.
Check also the high tension wires( spark plug wires ).
Hope Fixya helps you!

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Distributor Cap -- Distributor Cap Cracked or Burned.
3 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injector -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer -- Clogged or Dirty Fuel Pump Strainerat.
17 Inspect Engine Control Computer -- Incorrect Operating Information Being Delivered and Sent From The EEC.
18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

Three things to check: Coil pack (the main box that spark plug wires connect to), Spark plugs and wires, that's not what's it, your fuel pump is gone. Definitely would get a fuel pump either way due to stalling of the car and possible excess air and a coil pack as well do to a malfunction reading with the emissions module causing the spark plugs to lose energy all at once which then can lead to the coil pack going bad and sending false emission rate timings threw the fuel management system causing the fuel pump to have the sensor go bad. This happened to me as well. Same exact thing. After I did those fixes, car was like I have never driven a true Audi till that day I changed the coil pack and fuel pump. Eventually to be safe I got all new 4+ Bosch spark plugs and wires just to prevent and imbalances. Changes your car into a pure German luxury mobile.

Changed fuel pump. getting fuel to engine. but will not start.


Check for spark. Maybe a crankshaft position sensor is bad or a module.

Secondary Spark Test This spark tester looks just like a spark plug, attach the clip to ground and crank the engine to check for spark 91052p10.jpg
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems 91052p11.jpg
Attach the clip to ground and crank the engine to check for spark 91052p12.jpg
This spark tester is the easiest to use just place it on a plug wire and the spark voltage is detected and the bulb on the top will flash with each pulse 91052p10.jpg
The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available. The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse. The Air Gap type must be adjusted to the individual spark plug gap specified for the engine. The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump to. The last two types of testers allows the user to not only detect the presence of spark, but also the intensity (orange/yellow is weak, blue is strong).
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform diagnosis of the ignition system using individual component diagnosis procedures.

Ignition Coil Testing
  1. Remove suspect coil.
  2. Disable fuel pump by disconnecting inertia switch electrical connector.
  3. Reconnect the ignition coil electrical connector to the coil.
  4. Install spark tester 303-D307 (D81P-6666-A) or the equivalent.
  5. Crank engine while observing the tester.
  6. If a blue-white spark is not observed replace coil.

Removal & Installation To Remove:
  1. Remove the air cleaner outlet pipe if interfering.
  2. Disconnect the connector from the ignition coil. coilconn.gif

  3. Remove the bolt from the ignition coil. coilbolt.gif

  4. Remove the ignition coil on plug.
To Install:
  1. Install ignition coil on spark plug.
  2. Install ignition coil bolt. Tighten to 10 Nm (89 in. lbs.). coilbolt.gif

  3. Reconnect the ignition coil electrical connector. coilbolt.gif

  4. Install the air cleaner outlet pipe if removed earlier.

It sounds like you have a fuel issue or spark issue. Pull your spark plugs and see how they look. If they look fine then test the fuel pump. You could try to run to fuel system cleaner through the fuel system and see if there is an improvement in idle. Could be any of the following problems,

coil
spark plugs
spark plug wires
fuel filter
fuel pump
injectors
air filter

Check the easy stuff like plugs, wires fuel pump and air filter first.

pull your spark plug wires and look down to the spark plugs and make sure there isnt water in the spark plug holes if there is just blow out with compressed air to dry out.
and make sure the air box has no water and free from any debris
good luck
