No spark on 2 cylinders HELP PLEASE !!!

[YellowTSI]

Hi everyone !! I did some work on my : 95 Talon and I have this problem. I start the car and let it run for about 25 minutes . Everything seems right but burning smell. But it wasn’t like electric or plastic. It smells like the paper burn (I change down pipe , exhaust and turbo ) so I wasn’t worry too much. I shut off the car,and 20 minutes later when I try to start again my nightmare begin. The car doesn’t start! It cranks but wont start. I find out that I am not getting spark on 1st and 4th cylinder. I change the cables , ignition coil, transistor (cam sensor and crank sensor I change before I start the car ) and still the same. I got my brother to bring his 97 Talon and I switch the ECU. Now I got the spark on 1st and 4th ….but I lost 2nd and 3rd!!!!!! When I hook my ECU back ( 95 E prom ) no spark on 1st and 4th again !!!!! Please somebody HELP ME !!! It drives me crazy and I don’t know what to do anymore !!! Thanx Mike

I am having the same problem and have no idea what it is. I only get spark in 2 holes also. I did a 1g head swap and tryed a few ecu's and another power transistor. Still no luck. Post up if ou figure it out.

Did you check codes?

When my car was doing that it was a bad crank sensor. I ended up using the 91 CAS and rewireing it and n ow the car runs fine.

I didnt check the codes. I dont have the scaner and just lost OBDII from my palm ( Forgot to charge the battery ).

I didnt change the head ( thats original 2G head ) and crank sensor and cam sensor are from dealer. Also the car was runing fine untill I turn it off.

I don't profess to be a DSM expert so need to ask if you can't access the codes using the key switch for your year?

For my car, there is no code to read for the cell as it doesn't pop the light.

hey, my car isn't getting spark at all. i replaced the wires, plugs, distributor cap, rotor, and still nothing. i'm wanting to replace the coil, but i'm not sure where it is. i think it must be built in to the distributor, is this correct? if so, how do i get the coil out of the distributor? thanks.

 

[rodwa4]

oh, by the way i did check the fuel pump, and it is working.

UPDATE.
My sparks switch with ecu becouse i didnt switch cables with EPROM Ecu. But still only 2 cylindershave sparks.

Distributor? Did you ever get a shop manual for your car? have you looked at where your spark plug wires go to?

Yup, I picked up on that too... distributor??? hmmmm

[rodwa4]

no i don't have a shop manual. there are only 4 spark plug wires coming out of the distributor, and of course they all go to the plugs, however the coil is built in to the distributor, so you have to change the whole thing.

Rodwa4: YOUR car does NOT have a distributor... period. Please buy a manual and look it over so you can identify the correct part names and what they do, check the trouble shooting suggestions for your condition and then we might be able to help you. It would be best that once you get up to speed you might consider starting your own thread rather than assuming that the problems are the same. It's called hyjacking another persons thread... just something to consider, not trying to put you down.

rowda: you are referring to a DSM car, right? I'm going to spoon feed you here and give you a hint, there is no distributor on a DSM motor, the ignition is computer controlled & what the plug wires plug into are called coil packs... there's 2 of them, one fires 1 and 4 and the other fires 2 and 3 (I *might* have that wrong, it could be 1 and 3 and 2 and 4, but I don't think so) and they are controlled by the computer... if you're only getting spark on 2 cylinders, odds are one of your coil packs has gone out... however, I still haven't figured out how you replaced the cap and rotor.

My reccomendation is get a shop manual for the car... it's one of the best invesments you'll ever make if you plan on doing the work yourself... and they're only like 15 bucks.... I think I found one on ebay for $1 on CD....

YellowTSI: It's odd... the first thing I was thinking is that you had a coil pack that went out, but you say it that it changes which cylinders dont' have spark when you swap ECU's (which makes sense) so I'm going to have to go with one of your sensors is going out and the computer doesn't know to fire when you're in the part of the rotation that it should be firing those 2 in... that's the only thing I can think of... Anyone else know what triggers the firing... it's the crank angle sensor, isn't it?

 

[rodwa4]

ok, i'm really confused now. what i have is two 94 eagle talon dl's. on both engines there is a sticker that says, DSM. however, both cars definantly do have distributors, and i even went to the local parts store and purchased a new rotor, for a 94 talon. so i'll check into to it. also, sorry about "taking over" the thread, i won't do so again. i apologize.

FireyIce01 thanx for your reply. When I change the coil nothing change , it change when i swap my EPROM ECU with 97 ECU. But like I said thats becouse I didnt swicht cables.
So I am still at the same spot. No spark at 1st and 4th. :thumbdown .
Are you sure that crank sensor controll the spark not the cam sensor ?????????

Nope, I am not sure at all... but it really sounds like both coilpacks are good, so you're just going to just have to work through the ignitiuon system til you find out what isn't working right... I would suggest renting a code reader from the local parts store and see what the computer says about this.... it could make things a ton easier.

Exactly so.

Don't both of their cars have a cam angle sensor and a double crank angle sensor. If this is true then I would suspect that one of the sensors (coil pickup) has failed since firing order 1,3,4,2 has the same sensor firing 1&4 but but the other is not working 3&2. This should be covered in a test sequence in most manuals.

Look into it... I don't know schitt about the 420a, but I was pretty sure that the 1G 2.0 cars all used a 4g63 turbo or not.... I also don't know anything about the 1.8L motor, so if you have one of those, there's a possibility that it had a distributor, but I really don't know.

I didn't realize this was a 1.8 which I think does have a distributor. If that's the case it still may have 2 pickup coils inside. The dist. shaft could be damaged and/or the magnet may be damaged. I also think the 1.8 is a SOHC and not a DOHC.

I do think it would be best if he started a new thread and then posts here where it is so we can address the different thoughts needed to help each of them out.

Ok... Here is the update. I ended up at TURBOTRIX NJ. The problem was Cam Pos Sensor !!! I change the sensors before i start the engin but ..... somehow I bend the plate from cam sprocket !!!! I didnt even know when and how...I put it back on and it was hiting the sensor. So the sensor was BUSTED !!! That was the problem .. Now my car is running just fine .. THANX again Everyone ...Mike

Thanks for letting us know, would be helpful if you had some pictures so we can see what happened and be able to caution others.
