SOURCE: cylinder 2 and 3 are misfiring

The head gasket may have blown between 2&3, but if the cat is getting hot, your ECM may be holding your injectors open. I would first unplug your #2 and #3 injectors, turn the key on but do not start and check for voltage between the pins. The way this engine is set up, it is squirt #1 and #4 injectors at the same time and then #2 and #3 injectors at the same time, so by the time your intake valve opens, you had one shot suspended around the valve, and then another once the valve opens. The hot cat seems to to tell me that the fuel is burning off in the cat since #2 and #3 are misfiring. Problem is, most of the time the computer gives the injectors a ground while voltage is waiting, so you must check between the two pins for each injector or you will be providing a seperate ground if you ground the meter anywhere else. If the voltage shows between the two pins, then you need to find out whether or not it is the computer grounding the injectors, or a wire grounded somewhere giving the injectors a ground. Once you finally get this fixed, plan to have to buy a new catalytic converter, as it will most likely be plugged or about to be in the near future.

SOURCE: 1988 4 cylinder wont start, back fires.Has direct

have you checked to see if the injector is not leaking? this would explain what youre experiencing. another would be a plugged catalytic convertor. what happened when it died in the first place?

SOURCE: I have 1992 Pontiac Bonneville SE with 3800 engine

run engine until problem occurs. turn engine off or let it die. leave key on but don't start engine. put a paper clip in diagnostic plug under steering column. look at area on dash where service engine soon flashes. count flashes. (ex. 1flash-1,1 flashes=1,2. if you see 1flash of service engine soon, then 5 flashes in a row the diagnostic check = 1,5. It will flash this several times in a row. this is your code. look it up or ask and find out what it is. this is usually your problem area. let the car tell you.

SOURCE: I ave a 994 pontiac, bonnieville. about a week

there is probably a dead spot in the fuel pump,and when it is hot and you shut off the car it will not run.Next time the car does not start,bang on the gas tank with a piece of wood or spray some starter fuel in the throttle body. if it starts,it is a fuel problem.
use a spark tester to see if there is spark as well.ignition modules and coil packs are common on those cars,as well as the EGR valve getting stuck.that will cause the car to idle ok but die out as soon as 2500 rpm is reached.

Coil packs I replaced #4 and #5 went out. Why?


How to Tell if You Have a Faulty Coil Pac How a Coil Pack Works When creating a spark at the spark plug, the fire must initiate from a high voltage supply, so as much fuel as possible burns in the cylinder. Whenever the combustion process is started, the coil pack builds up the energy, as much as 50,000 to 75,000 Volts. When the electronic control module (the car computer) sends the signal to the ignition control, the voltage is released from the coil pack through the spark plug cables to the spark plug.
When the spark travels to the spark plug, it jumps from the spark plug gap to the ground, causing an explosion of the fuel air mixture inside the cylinder chamber Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what's commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine Common Symptoms of a Faulty Coil Pack A faulty coil pack will generally have symptoms similar to a faulty spark plug. Some of the most common tell tale signs that a coil may be defective include:
  • A rough idle
  • An unexplainably louder-than-usual engine
  • A noticeable lack of power
  • A significant drop in RPMs while accelerating for no apparent reason
  • A blinking or intermittently activating check engine light
  • An active gas warning light when the vehicle has plenty of gasoline
  • Smoke from the exhaust emitting intermittently, instead of in a steady strea How to Test a Coil Pack Fortunately, there is an easy way to test the coil packs in your vehicle and make sure they're working as they should. You need to use ohm meter to test the coil pack for continuity. Make sure you have the approximate ohm values for the coil pack. To find this information, research your car's engine on the Internet or purchase a Chilton's or Haynes manual to find out what the mega ohms reading on the coil pack should be. What Coil Pack Works with a Rotary Engine? Most rotary engines require a different type of ignition coil pack. Below are two, one for a standard replacement, and one that is a higher voltage performance type coil pack.
    Original Equipment Replacement
    Beck Arnley is a well known name in the automotive ignition parts industry. They are favored by many mechanics, especially those that work mostly on import cars. The Beck Arnley 178-8025 rotary engine coil pack is a direct replacement for original equipment parts on older Mazda cars with a rotary engine. You can expect to pay about $55 for one.Performance Replacement
    M&W Ignition Systems is a fairly well known name in the import performance market. Their part number PAK005 is a high performance ignition coil pack for the performance enthusiast who isn't afraid to spend a little more on a high quality high performance part. With prices running around $245 for a double coil pack for direct fire ignitions, these coil packs will deliver years of excellent performance.
    When ordering a coil pack for your rotary engine equipped car, you need to know the year and model as well as the engine displacement to ensure you are given the correct parts.

Initial start up the engine sounds like its running on 2 cylinders under powered intil the temp gauge reads normal ???? any body got the answer please


Cold starting misfires can often be caused by either tired high tension spark plug leads or ignition coil packs. If replacing leads, then replace with a full, new set. Coils can be changed individually, but it is often the case that if one has failed, then the others aren't far behind. Some cars have individual coil packs on each spark plug. Some cars have a single pack for all plugs and some have coil packs which may control two or more plugs.

To check for a misfire (ignition failure) follow these steps:

(Cold start) (Use a pair of insulated pliers)

1) Start the vehicle

2) When the vehicle starts misfiring, disconnect plug leads or coil pack connections one at a time. If the vehicle idles even more roughly, then that plug or pack should be considered fine.
Replug each connection before disconnecting the next one. Once you disconnect a plug lead or coil pack connection and find no difference in poor engine running, then you have likely found the offending cylinder. Check the spark plug condition, lead and/or coil condition and connections on that cylinder.

3) Replace components as necessary.

05 Ford Escape, coils #3 & #4 not firing. We've replaced the battery, spark plugs, alternator, coil packs, & pcm. Had pcm reflashed. Garage said it had to be coil packs, but just replaced coil packs 3


Check engine light on ? Code's ? What engine ? 2.3 l 4cylinder or 3.ol v-6 This vehicle has coil on plug ignition system , not coil packs ! a coil per cylinder . If new coils an still has no spark , has no B+ voltage to the coil or the PCM isn't controlling them . Without testing i'd only be guessing as to the problem .If the repair shop you had it to can only say it had to be the coils , I'd find another shop to take it to !

Need a cylinder wiring diagram for 92 buick park avenue


Buick Park Avenue has Type I coil packs, three twin tower ignition coils are combined into a single coil pack unit, and Type II coil packs, the coils can be replaced separately and the ignition wires are all on the same side of the coil pack.

Where are the ignition coil packs and how do I remove them?


The coil packs sit on top the the engine. As you open the hood toward the rear of the engine you will see four cokl packs sitting on the engine. There are 3 10mm bolts holding the bracket that holds all the coil packs. You can remove them all at once (easier) or try to remove coil packs one at a time.

You shouldn't have to remove it....here are the steps from the tech manual:

Removal & Installation
  1. Disconnect the negative battery cable.
  2. Label and disconnect the spark plug wires from each of the coil pack towers.

  3. Remove the coil pack from the vehicle. If equipped, remove the coil pack from the mounting bracket.
To install:
  1. Place the coil pack into position on top of the engine valve cover, or mounting bracket, if equipped.
  2. Install and tighten the coil pack mounting fasteners to 9 ft. lbs. (12 Nm).
  3. Plug in the electrical connector to the ignition coil pack.
  4. Connect each spark plug wire to each corresponding coil pack tower. The coil pack towers are numbered with the correct cylinder identification. Be sure that the spark plug wires snap firmly onto each coil tower.
  5. Connect the negative battery cable.

Engine loss power good fuel but no spark at coil or plugs


Check the grounding surfaces on the coils. Also, check your ignition module, it may be malfunctioning.

Many coil problems are actually caused by other malfunctions.

I'd go ahead and change the plugs and wires anyway since it's always a good thing to do. I'd definitely start checking connections on the coil pack and ignition. It's most likely a problem somewhere in that range.

I hope this helps a little. Spark problems can be led from many different areas.
