Starting problem

[Dakota Biddinger]

Replaced the engine in my 95 talon tsi, and have yet to get it to start fully. Today when I was cranking it, it started for like 5 seconds and idled then died. Now when I try to start it I can hear cylinders firing but. It won't fully turn on. It'll crank for a couple seconds then it will sputter but won't turn on. Any help would be great.

Sounds like a bad PTU. Need to check for spark, a spark tester is about 5 bux at any parts store, or you can pull plugs and ground to intake manifold (any bear metal should work) while cranking to check. If spark is weak (orange or yellow is weak, bright blue, just like lightning is good) I suspect the coil pack may be shot. It's possible your crank sensor is bad, damaged or unhooked, but I don't recall if 95s have a CKP or not, in which case it could also be a bad CAS.

From your description, fuel doesn't seem to be the issue.

I did buy the coil pack off of eBay, but the guy had 100% positive reviews so I'm not sure. I'll go to oriellys and get a spark tester in a few and test them. And it's a 1g engine

 

[joemamma]

u can buy them brand new frm the store and they could still be bad---i have bught brand new parts that turned out to be bad, crap happens, most likely not the sellers fault

 

[Dakota Biddinger]

So I tested the spark and it seems to be good, I could be wrong though. On the one spark plug that was dry when I first checked, is still dry even though I tried starting it again. I smelled the spark plugs and I couldn't smell any scent of gas on it. Does that mean that fuel injector is clogged or something?

 

[joemamma]

in that case it could be : ecu, filters, injectors, wiring.... are next thing to check

get a noid light and see if injectors are firing

could have pinched a wire putting engine in--double check that all the sensors are plugged in and connected properly---it is easy to damage a sensor re-installing an engine

I'll have to get a noid light from my friend but I'll test the injectors once I do. I should be able to get It in a day or two.

Its a 1g engine in a 2g chassis so im assuming it has a cam angle sensor also....? That could be 180 degrees off also.

 

[joemamma]

even 180 off it should fire the injectors

 

[Macgyver'sDSM]

Mine will not run well if at all when my cas is 180 off starting then turning off but yes it should acivate the injectors. It only takes 2 minutes to check the cas sensor for proper alignment.

Like everyone else has mentioned I would check fuel and spark before anything else.

I've tested one spark plug and it did fire, I just have to wait till Saturday to get the noid light to test the Injectors. I'll check all the spark plugs to see if they all spark today

 

[Dakota Biddinger]

To test the injectors do I just poke into the wire and touch the ground to a piece of metal or do I have to actually crank it to get the current to go through

 

[joemamma]

has to be cranking--need someone to do that while u look

Alright I'll do that. So if there's power to all of them they could be stuck partially open, or it could be coil pack, plugs or wires ?

 

[joemamma]

if they were stuck partially open you would be flooding the car all the time

and i just read u tested only one spark plug wire/ u need to test all--just like injectors all will need to be checked

So I have a little two prong voltage tester, do I just poke one end into the injector wire then touch the ground to metal and have somebody crank it ?

I got it running but the head gasket is blown apparently

dang sorry to hear-"when it rains it pours"
well at least while u have it apart u can upgrade stuff

Definitely true. And at least it runs now
