Delayed startup

[nyTalonTsi]

I have had this car for a little for a month now. It was sitting for a while when i bought it.

Now ive done a list of maintainence work to it. Plugs/wires etc...

The motor takes like 4-5 seconds to crank when its cold, but even when its been off for a min it will take forever to crank then too.

Ive been thinking it might be a clogged fuel filter, i bought the filter but have no time to tackle the pita removal, along with changing the timing belt. Ive only used 93 at the pump on every fill up, so i thought maybe it would clean it up a bit. I was getting crappy mpg, i get 19mpg now.

Along with the delayed start, the car sounds like a little misfire at idle. But it drives very well, no sluggish or feel of loss in performance. I never had a completely stock dsm before so i don't really know how smooth they ride. My last one was heavily modded.

Only CEL it was throwing was for an isc that i replaced, after i sprayed the throttlebody with t/b cleaner the car started right up after the motor cooled down. It did this twice, when i cleaned the t/b and when i replaced the isc and sprayed fluid into the tb and intake.

Which makes me believe its a fuel issue. Don't know whether its the filter or fuel pump.

try seafoaming it. after that i would check compression and do a boost leak test.

Motor is fine. I believe its the fuel pump failing. Takes a while to build fuel pressure.

Are the coolant lines connected to the tb or did someone disconnect them?

 

[nyTalonTsi]

No the coolant lines are still connected to the tb.

Quick question for you. Once you get it started and drive around if you turn the car off does it still take awhile to restart or just fire right up? I am having the same problem with the starts and I too feel like it's some sort or fuel issue. But the warmer it is out the quicker it starts up. Once I start the car and drive it around the car will fire right up when I turn it off.

 

[nyTalonTsi]

Theres times i shut off the car for no more then a minute, and it wont start right up. Mostly does start up quick after i just turned it off. And when its colder out yeah it takes longer.

I believe its a fuel issue, like i said in my o.p. the couple times i sprayed intake cleaner into my tb it started right up on a cold start. Then went back to its old ways.

Coolant Temp Sensor maybe?

Coolant Temp Sensor maybe?

I never thought of that causing the problem but you may be right because my CEL is on and the code is coolant temp sensor.

I had some REALLY weird issues when my CTS was on.

Car wouldn't even start sometimes and I'd have to let it sit for 10 minutes and then it would fire up. I think the ECU just thought it was too hot.

quick question. the coolant temp sensor on my car is bad and the guy pulled it out.would it hurt to crank the car up and drive it to my buddy shop 10 miles away?

could be a leaky injector. my car would take forever to start and when it kicked over it would burble to life and then be fine.

changed the injectors out for some bigger ones and the problem went away.can also happen if you have a bad boost leak that makes the car run real rich.

take the plugs out and smell the spark plugs, if it smells like gas real bad thats your problem

Is the sensor still there and just unplugged?
If there's a hole there, coolant will piss out all over. If it's unplugged the car won't run right.
Personally I don't like driving my car any distance if it's not running right.

Best thing a DSM owner can have imo, a AAA/CAA membership

 

[93spoolin]

yeah it was broken..so he pulled it...and the douche bags at autozone said they dont know what im talking about talons never came with them..


what will not run right?the guy i got it from said it was stuck in cold mode or something.

 

[jrohner]

You need the coolant temp sensor to run right. It's the one with a 2-wire plugin. The 1-wire one is just for the gauge and has nothing to do with how the car runs.

 

[93spoolin]

ok.does the temp sensor off the 1g n/a work?on my 93 tsi awd?

 

[Blurred Talon]

No the N/A part is completely different.

Go to NAPA, Autozone is for ricers.

 

[nyTalonTsi]

Well, it just through another CEL on my way to work. Might indeed be the cts.

I was also thinking it might be bad injector(s) cause i get like 15mpg and i drive it like a old lady.

 

[boostd_mitsu]

When a cts goes bad, it tells the computer that it is 44 below zero. Same as when it is unplugged. When the computer sees that it starts dumping gas in to make it rich to get the motor to operating temp. That's why you have bad mpg, and why it starts hard. Out a new sensor in and are what happens.
