2G Engine dies and won't start at least once/day.

[Dsm304]

I have a 95 eagle talon tsi im having the problem that when its running the engine shuts off while running and when trying to turn on bak again the car will crank and crank and wount start for a while it happens atleast once a day please help!!!

Start by checking the ECU, open it up and make sure it's ok, also make sure the grounds around it are good too.

 

[Dsm304]

Im gonna have it scanned today ### the check engine light turns on at times also I think it might be a sensor because when the light turns on it only turns on for like 2 to 4 seconds and when it does it wants to turn off

 

[jcarmichael]

do you have any more specifics? Is it shutting off when you come to a stop. Could be alternator, bad idle speed control motor, bad boost leak. Just depends on what its doing exactly before it dies.

 

[Dsm304]

I believe I have a boost leak since I just got the car 2 days ago from an owner that was misstreating it because when u give it a little gas it like studders and the exhaust sounds like miss fireing when it studders ima do a boost leak test this weekend and the car turns off whenever it wants to but only like once a day it could be in a stop it could be running and making a turn

Also it just turns off all of a sudden like it doeaent do anything beforw it dies it will be runing fine and all of a suddent u just hear a small tick sound see all the neddles on the dash go down

 

[jcarmichael]

Yea boost leak would be a good start place, also might check your spark plugs. I say that more because you said the guy abused it and who know's when he changed them last. The plugs, ecu or boost leak could be causing the missing out easily.

also I was referred to this the other day, because I was having the same issue and I checked mine on my lunch break with in 20 mins.

[Dsm304]

Yeah thanks for the help guys and the video hopefully ill do all that by the end of this weekend also do u recommend some good spark plugs & store?

 

[DCGuerrette89]

sounds like it could be a bad crank sensor or a short in the wire goin to or from it from the ecu to the crank sensor because the crank sensor tells the the ecu wehn to fire the coils so if its giving u an intermitent problam it would be cutting out the signal to tho coil to creat spark. i had a simalur problam with my mazda that i had but that turned out to be the ecu

if u want good plugs get NGK Irriudems there like $8 a plug up here in CT

 

[jcarmichael]

you might do a search but what I found and what most people recommend for my year atleast would be ngk bre6es. I believe that's the part number but basically its just regular copper ngk plugs. You want them to be 6's. If you don't have any mods as you get more mods then you go to 7's and so on. autozone by my house doesn't carry them in stock but o'reilly by my house has them in stock.

also gapping is between .028 and .031 on the plugs. good luck, I will be chasing down boost leaks on my car all weekend as well.

 

[Dsm304]

Yes it could be that also I might check that also I just wanna save this talon because its been treated badly the previous owner dint know anything about these car I dont neighter but I kinda do know some stuff ima scan it today to see if I can get a code of the check engine light turning on at times

Nice one thing for shure is that ill never buy a part from autozone again >:/ ill keep everyone updated on the things I do and what the car does and the car doea have some upgrated parts like the greddy intercooler greddy 3in exhaust and mufflerit also has the accel 8mm 300+thundersport sparkplug cables it has the hks turbo timer the apexy s-afc2 super airflow converter and a greddyprofec-b thats not working :/ I believe thats it the previous owner said that the car had the 225walbro fuel pump wich is loud and the 550cc fuel injectors wich I still dont believe ### I can see them but I dont see any sticker on them saying 550cc

Oh also a greddy bov

 

[Willbr]

iu have only heard of b ad things from the E3 plugs just try and stay away from them bro.. best of luck dude..

 

[Dsm304]

Oh ok thanks willbr

 

[aj2494]

It almost sounds like a fuel delivery issue to me.

 

[Willbr]

ah i wish i could be more help..... im new to the dsm's ill keep researching though... cant get enough of info that is like candy for the brain ..... sorry had a motorhead moment there

 

[Dsm304]

Fuel delivery im not too sure about that ### the car runs fine its just sometimes when it shuts off completely when running and it dint turn on one morning eighter it just cranked good but never started till mid day :/ but it cam be idk ill check the fuel pump and fuel lines this weekend if I have enough time

 

[Pain715]

I kinda have the same problem, except my car wont start anymore. When it did it run i pretty much had to flintstone it, idle real low, battery always drained but i had a bad starter, miss fired ALOT and die driving down the road, most of the time i would turn the key over it would fire then shut right off. Its not getting any fire from the coil, i changed coil pack, plugs & wires, crank sensor, timing belt is good. I kno its getting fuel because its flooded(was till i changed the oil). Last time it started it died then i had to jump it and wasn't paying attention and i stuck the cables on backwards, never started since. Could this be a fried ECU, im getting one tom just to check. O i even hooked it up to code reader and it said connection error, check connections....

o and i have no cel

 

[Dsm304]

Haha willbr same here ive been into the dsm's for a year now but this is the first one ive had with a 4g63t haha but I dont know alot alot of these cars but any help and any tought helps

 

[aj2494]

The only reason I said that is because my mustang (current car, but hopefully not for long), had a problem with the shitty CAI the guy before me had put on. One section of pipe wasn't long enough and kept separating just enough so the MAF wouldn't get enough air flow at times. So at stops or during turns (basically low RPM's), it would cut off the fuel supply. However, in my case, it would usually start right up after. Just a thought.

 

[Dsm304]

Aj2494 oh ok the rpm in my car is weird at times is low and at other times it stays kinda high

 

[Willbr]

ok if your looking for a cheap way to test for a boost leak just find a propane torch and spray the propane around the different parts of your intake. if your car is running the rpms will go up from the cleaner burning propane.. and i would check the Idc ( idle control valve which correct me if im wrong is on the throttle body. it might help if you clean it but would be best to replace if that is the cause... also somtimes fuel filter will get clogged and not allow fuel to pass through sufficiently to keep the car at a decent rpm level.

 

[Dsm304]

Im doing the boost leak test with water and soap on the pipes and stuff thats how one of my frie.ds told me to do it I dont have a torch propane I will take a video tomorrow so everyone can see how the car shounds and the rpms and stuff

 

[Willbr]

sounds good. id like to see the outcome.

 

[Dsm304]

Yeah hopefully I can find the leaks and fix that part I still need to figure out y it turns off

 

[Willbr]

i dont know why it turns off could be a leak causing a faulty error code sent to the ecu therefore making it shut down in hopes of temporarly fixing it self....

 

[miguelmcv]

I am with aj2494.

It sound more like fuel issue.

Do you have a FPR?.

With a 225 fuel pump, it does need a FPR, and if you have bigger injectors, then you need some sore of tuning device.
Also, Check your fuel filter, If it is dirty, it will do exactly the same thing that you have, Once it runs the it will keep running and some times it just dies.

Take some pics of the Injectors and post them here to see which injectors you have.
