Help diagnoase, video included!

I have been having problems getting my talon started after a recent problem with my coil pack and PTU! I decided i would go and take a video of how it was cranking to see if i get get some help and lo and behold the talon starts for the first time in like a month and a half. It would start only if i floored the gas as i crank it. It started but mad a horrible sound accompanied by some smoke. It did start and I am super happy about my progress. I went through every wire from the ecu and made sure all connections were good and electric taped them all up. I checked all the wires coming from the PTU, injectors, o2 sensors, the CPS, the fuse box, and any other wire i could find. Brand new plug wires and plugs. I new known working PTU! So please check out the video and help me if you can! greatly appreciated i cant wait to feel the boost again.

you need a new engine

Why would you say this??

 

[darkiller_666]

Ok well tomarrow i plan on checking the wires from injectors back. Is there a way to check it with a multimeter? Like I said it sounds like the wires are shorting somewhere but I couldnt narrow it down. Im gunna try switching the injectors around to check and see if they work in reverse order.

 

[hpexperts]

make sure your spark plug wires are not crossed but parallel, this would cause the wires to short out, do you have a scan tool where you can read live data?

You need to buy a service manual from mmc.

 

[darkiller_666]

I dont have any scan tools. But from the videos you can tell there is spark in the first two cylinders. I tried switching the two around and it didnt help any. I tried changing the plug wires in all sorts of different orders. The way it is now is the only way it will idle on its own and run without hitting gas. Does anyone know how to check if the injectors are getting a good signal?

 

[myturbo]

I guess ill try searching more.

you can test spark by takin plugs out and putting them in spark plug wire and seeing if they spark IM PRETTY SURE ILL BE COMMING DOWN THERE THIS FRI OR SAT OR SUN NOT FOR SURE MY CARS TRANNY IS CURRENTLY BROKE AND YES ITS CAUSE WAY TO MANY CLUTH DUMPS WHAT CAN I SAY IT"S FUN!!!

I doubt it's the injectors. Looks like the wiring.

 

[wickednightmare]

IT CANT HURT TO TRY

ok if you take a aaa bat. and run leads from pos and negative to your injector while its out and it should open and close make shure ## blowing threw it u will allso hear it i did this and it works to to tell if they open and close or not

 

[darkiller_666]

i believe the 2gs are 450cc inj. I used to have a SafC but someone broke into my car and ripped all the wires out of it.

 

[darkiller_666]

I plan on switching the injectors from 1and2 to 3and4 and see if the other cylinders will fire with injectors traded out. that should let me know if it is the injectors or wiring/ecu problem

PM sent to you Myturbo

yes there 450cc i have a wireing harnest with an safc wired in so its all plug in play let me know if it would help

Make sure your Ignition transistor isnt the problem. When your car is running if your tach shows about half of what the rpm should be then the transistor is probably bad.

 

[darkiller_666]

I have tried several PTU's. I took the fuel rail off today and turned the car over. There is fuel coming out of the injectors. I know i have spark, i know i have fuel. Any more ideas? I did notice the wires coming out of the ecu have been hacked through before. I dont know if it had something hooked up or what. I tried cleaning it all up as much as possible. Is there any certain pin or wire i should check for continuity or just check in general that might cause this problem.

 

["G"]

Your injector can be dripping & it will still deliver fuel. Doesn't mean they are getting power.

 

[darkiller_666]

do you know how to check them with a multi meter or something?

 

["G"]

Dude you need to buy a service manual & check to see if your injectors are getting power.

 

[wickednightmare]

Why would you say this??

you said your results of the comp test was 145 i think they should be like 160 or so im not to sure maybe its time for a rebuild at least a good hone and rings

 

[darkiller_666]

i said 155 and that was on a cold engine cold day.

 

[wickednightmare]

you need a new motor.

sorry but maybe you ment 155 but it says 145 if you say your ecu harnest was all jacked i would fix it what kind of fuel pump and are you running do you have a regulator

who cares about his wing at least its not a honda hes driving try bein helpfull anyways

recheck ## timming

 

[darkiller_666]

Why would you say this?

hey man how much vac are you pulling at idle

 

[darkiller_666]

Big update. The good. MYTURBO drove a few hours to come and help me check out my car. We got it firing on all 4 cylinders!!!!! The bad... i have a blow head gasket. So tomorrow i will for the first time take the head of and have a look. Hopefully the head is still good. If not ill be spending the whole day putting on my new head. Going to have it decked and sandblasted and polished!

 

[nyTalonTsi]

What was the final reason for only 2 firing cylinders? Wiring? Or your injectors were shot?

 

[darkiller_666]

I am unsure to the exact reason. I put in new injectors and i went through a lot of wiring fixing odds and ends. The one thing i have learned about dsm's is that the fix to anything takes patience and never giving up.
