1999 saab 9-5 stalls without warning won't restart for 30-40 min.

No ckeck engine lite or codes at any time. After first time, replaced spark plugs, fuel and air filters. Did it again, replaced ignition coil pack. checked and had voltage on pin 6 &10 on the ignition coil pack. waited 35 min. and started. replaced battery. no change and still no codes or ck engine lite. It only happens when the car is hot. Tried letting it sit and idle for over an hour, no problem. Drove it 8 mi. stalled, sat 40 min. started and drove 6 mi. stalled, sat 35 min. started and drove 3 mi and parked it.

    I just bought my ranger rover 2000 from an auction I was told it need the ignition fuse. We drove it home no problem about 19 mi. when I went back out to start it a couple of hours later it died. would not start for a couple of hours. After finding the reset switch it did restart then in about 1- min died again when we turned off the key back windsheild wiper and a lot of the other thing came on in the car. after finally getting it shut off as soon as we opened the passenger car door to get out the windsheild wiper came on again. Is this an ignition fuse or what is going on Seems possessed

2.3 mazda millenia s will not start


faulty ignition pack
the ECU detects a fault and runs the engine for 12 cycles and then shuts down
remove the packs on each spark plug and place one at a time on one of the front pack connector with a spark plug inserted into the end and grounded
turn the engine over and you will get a spark ...test each one of the coil packs until you find the one that does not spark ...replace pack
I assume that your model is a 1995 with coil packs with 4 pins ...if they are 3 pins disregard the above

Sounds like something getting warm/hot as engine warms up. Could be the MAP sensor, Coil/Coil pack, Ignition Switch(not the key cylinder), or possibly the Oxygen Sensor.

Next time it does this, pull a plug wire out of the coil pack and hold it close to the tower, and have someone crank the engine to see if your still getting a spark.
Could also be a loose connector on the throttle body injection, or a broken wire.

When i start my 2001 kia optima my car putters. i changed my bad o2 sensors. but not sure what the problem is. and when i drive sometimes it jerks. what could the problem be


The spark and fuel system needs to be inspected.--------- The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.--------------- The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.----------- When coil pack stops giving power to spark plug the car will **** while driving.---------- So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.----------- ------------------ Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.------- In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.----------------- But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.

No ,,No fuse controling spark,,Your coil pack on top of motor could be cracked and causeing this or your fuel filter, or fuel pump, you could get a pressure test done to your pump at a garage,Check your spark plugs,change them if you can, change the fuel filter a good place to start,,,,,,,,,,,,Also is there a check engine lite on in the dash cluster? If so go to Auto Zone parts store and get a code scan done its free,,than they will give you a print out of the codes and what needs to be replaced,,most vehecles in the 90,s have or need 02 sensors that control your air fuel mixture,,,were talking gas mileage here.

P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

Changing spark plugs


Changing the spark plugs on a 1997 Ford Expedition 5.4L engine takes patience. Remember to start this project on a cold engine! I started on the passenger side by locating the Coil over iginition coils and cleaned out all the old dirt using some compressed air. Then I had to disconnect the electrical connections to both the Coil over ignition coils and the passenger side fuel injectors. Once you remove the small bolt which holds the ignition coil in place, use your compressed air again to blow out the spark plug hole. After that, you will need a 5/8" swivel spark plug socket and various length extensions to remove the spark plugs. Take your time because there is not much room for your hands. Before installing the new plug, check the gap and use clean engine oil on the new threads. Tighten the new spark plug and reinstall the coil over ignition coil. Reconnect the electrical connection to both the ignition coil and the fuel injector. Continue these steps with all eight spark plugs. You will find the ones on the drivers side are difficult because of the fuel rail gets in your way. Have patience and use swivel extensions to work around the tight spaces. When you are done, you will have saved lots of money! Don't forget to replace your air filter, fuel filter, and pcv valve to complete your tune up.
