I have a 1995 Saturn Sl1 and the Saturn tech's solution of 4-1-2-3 works perfectly for it as well. YES, it may be different from what others tell you, but isn't it worth a short, if your car is running poorly after a tune-up? In my case I removed all spark wires while changing wires and plugs, and put them back in the 2341 I thought they came off in. It remained really rough until I made the change as specified above.

AnswerHey Denise==It is 1-3-4-2. GoodluckJoe AnswerActually its 4-1-2-3. I am a Saturn tech. Answeractually if you read the manual mr Saturn tech that is supplied with the car it does say the first one not 4 1 2 3 maybe you people should fix your manuals if you don't believe me I'll scan the page, what a misprint, you could ruin your car then Saturn should be sued for putting damaging information in their manuals AnswerThe Saturn Tech is absolutely right. I came to this site trying to find the firing order because mine was askew. I used his answer and my car started up very smoothly.

Thank you for the answer Saturn Tech, it was 100% correct.

Also, i don't know what the thing is the spark plug wires attatch to is called, but if you look at the front of it below the four nodes its labled.

4/2 1/3 4/2 1/3 (Left side/Right Side) Which further proves his answer (too bad i couldn't figure that out for myself.)

4 1 2 3

See how they line up?

Thanks again.


AnswerHello I have a 1996 Saturn Sc2, I just bought it for my girlfriend. It wasn't starting whatsoever, I changed the plugs which were toasted, also added some new gas, and charged the battery for over 24h. I adventually got it running, it seems to idle around 1000rpm,and dies out without the foot on the gas pedal and also has a serious lack of power, I think it is running on 3 cylinders myself. I am thinking several things, wrong type plugs, injectors dirty or clogged, bad wires, and have an incling that the firing order is out of whack, from left to right I have 2341 (all the wires are the seems to be the correct length going to each plug, below on the coils someone has written the numbers on the caps 1234, can you please gimme a hand with this problem.

Thanks Jase Paterson

Answeras far as the car dieing if your foot isn't on the gas you should have the EGR valve checked out. my car was doing the same thing and what happend was the egr valve was clogged with carbon and it was sticking open which causes the car to die. I had my mechanic friend look at it and he was able to clean it out with some carbon cleaner and i didn't have anymore problems with it and that was over a year ago. If the valve is the problem then you should try to see if it can be cleaned b/c they are expensive. The valve is right on top and very easy to get to. Just a suggestion from personal experience. AnswerI don't know what is going on and why there seems to be different firing order information. The Saturn Manual states 1-3-4-2. This site which I have never found to be wrong states 1-3-4-2. Take a look for yourself. Answeraccually, both answers are correct, the fireing order for the motor internals is 1-3-4-2, if you are running the wires from the coil pack to the plugs, the order of the coil pack assembly is 4-1-2-3. during opperation the pulse width from the cranksensor triggers the ignition control module to fire correctly, the control module will send spark through the second tower on the first coil pack first, this is cylinder 1, the next pulse the module will send a spark through the second tower of the second coil, to cylinder 3, and so forth to complete the 1-3-4-2. The reason they alternate coils is to prevent them from overheating, besides, every motor ever created will always start with cylinder 1 fireing first.

first of all reword your question. second is you need to check your starter and see if it is firing right then check your fuel lines for a leek or there could be something blocking the flow to the motor. if everything checks out then you need to take it to a proffessional.

Where is the starter located on a 91 ford escort with the 19L or could there be another problem because it will not even crank has new battery?

Make extra sure that the cables are good and not corroded and green inside and that the ground is on bare metal. Then look at the solenoid located near the battery it connects to the red battery cable. Check these before you think about replacing the starter. The starter is found by following the battery cable from the solenoid; it will lead you right to it.

Are runways designated with letters then numbers and taxiways are designated with letters?

No. Runways are designated with numbers that are based on the magnetic heading of the runway. Runway 36 is on a magnetic bearing of 360 or magnetic north. Runway 18 is on a magnetic bearing of 180 or magnetic south. A runway may carry a letter such as 19L and 19R where there are two parallel runways, a Left and a Right with the same heading. Taxiways are normally designated by a single letter, but if an airport has more than 26 taxiways, they can be designated by two letters or a letter followed by a number.

What is wrong with a 1993 Mercury Topaz 19L auto that turns off when the engine is warm in neutral or park and sometimes also turns off in drive at low speeds of 5-7mph?

I had the same problem in my 93 2.3L. The engine would die when i would put it into park after driving for a while, and eventually started to stall on the road at very slow speeds. The problem was a bad fuel pressure regulator. It wasn't a cheap fix, but i brought it to a dealership. I would imagine that it isn't a difficult fix for a more knowledgeable person.

How do you rebuild a 19L engine on a 1995 Mercury Tracer?

The answer cannot be posted on line. Too much information and variables to post here. Purchase a repair manual at most auto parts stores for instructions. You better be skilled before attempting this. This is a job for someone who knows what they are doing, not an amateur. I was forced to rebuild mine when the #4 intake valve cracked and dropped into the cylinder. Yes, you will definitely need the repair manual, a comprehensive set of hand tools, a good torque wrench, a cylinder wall hone, an air compressor, and a means to hoist the engine. Also something else to drive- it took me almost three months to complete. But the job is doable- I have over 110K miles on the rebuild and it is still running strong.

How do you change a timing belt on a 1990 ford escort gt 19l?

Jack up the RF corner of the vehicle and remove the RF wheel. Remove the front motor mount located on the right fender apron and support the engine by the oil pan using a floor jack with a block of wood(You will now be able to jack the engine up and down as you need to). Remove the serpentine belt and if there is a belt tensioner in the way of the timing cover, remove it too. Remove the crankshaft pulley and remove the timing cover. Remove the old belt, and it is recommended that you replace the water pump at this time as well. Line up the crankshft timing mark (the keyway will be pointing straight up), and line up the camshaft timing mark(an arrow cut into one of the windows of the gear lines up witha dot on the cylinder head). Install the new belt ad reaasemble in the reverse order as disassembly. i had found eaven with the mount disconected i coud not lower the moter far enough to get anything on the crank pully bolt so i ended up cutting the weel well and bending it up so i could.
