92 eagle talon hard to start

[speedster666]

ok i read the other post it coverd about everything i have checked and tried and im still stumped.
i have a 92 eagle talon tsi awd its very hard to start and somedays it wont even start. now when its warm the only way to start is to either pull start the car or unplug the mass air flow sensore, and sometimes then the car wont even start. I have checked all the temp sensors the only one thats bad and not reading corectly is for the a/c fan controles. Along with this i have set the timing perfect it runs and drives great.
I have also replaced the vacume hose going to the fpr (fuel pressure regulater) checked compression i think it may be a little low but with it being turboed it might be about right it sits about 90psi all the way across give or take 3psi. One thing i noticed, which i think might be my vacume gauge im using, is that it one day it has 6lbs vacume the next its about 15lbs which is still low. I have also check all injectors and all check out have not done a fuel pressur test yet, as to the fact i can not get my hands on a kit that will hook inline since there is no bleeder.
Now something i have found funny is i cant even use starting fluid to assist in the start
this also might help with whomever assist me is when i got the car i got it with a blown headgasket replaced that alonge with bolts along with that the turbo was shot i also replace and like i said once i get car started it runs and drives great just cant turn off or i drain battery trying to start im not sure if i have the right size battery in it also so if someone knows the min cranking amps the car requires that would be greatly apreated
this is getting old and im tierd of checking everything over and over i would relly like to get it going so that i can start driving it any ideas are greatly apreated

Well first of all, you need to get your grammar together, it seems like one long sentence. you need fuel., spark, and combustion. Check those things. there is a thread somewhere on no starts.

 

[speedster666]

all i saw was one from 06 and it covered everything else yes i have all that but it seems to have all but im wondering if theres somthing im over looking causing it to get too much fuel or not enough.
sorry about gramer was never good at writing or reading

 

[92AWDHX40]

Montana hugh nice there been there last summer, anyway try a coolant sensor again, check the fuel relay.

 

[speedster666]

i love it but realy cold right now. which fuel relay the one for the pump or pressure regulater i checked the temp sensor agian this morning cold and it read right than again when car was warm and again it was getting less resistance. if i unplug it car wants to die so im sure that its good.
now the temp sensor for the fans has no resistance at anytime but i wasnt thinking that wouldn't cause any issues with the starting, but just make it so the fans dont come on.

 

[92AWDHX40]

my sensor for the coolant ws bad and my dsm didnt start, check the plugs sometimes for fouling. just the fuel pump, lost my book, search vfaq.

 

[speedster666]

oh im kinda thinking battery might be wrong size but not sure what the right size is tonight im going to try my trcu battery and see what happens i was kinda thinking it not getting enough amps to turn starter along with provide spark and fuel. could that cause the same problem?
note: the battery is new just not sure if big enough.
and what should my compression psi be on this motor its the 2.0 im kinda new the tubo gas engines

 

[92AWDHX40]

battery could be, but compression 160 around there for the turbo car.

 

[92AWDHX40]

Im kinda stumped.

 

[speedster666]

the ratio in the book says somthing like 8:1 well it not exact, and im only getting about 90 all the way across i might have to get the head worked. that was the last time i checked it that it was 90 i havent checked since i changed the head gasket again and bolts but that might be part of it ill check tonight and let you know if its low.
can these heads be shaved at all or is it to low tolerence.
yea this things been stumping the heck out of me now toyota engines i have been able to troubleshoot without a problem
for exaple i put a 3.0 f/i in a 22r carbed truck that was simple compared to this

 

[92AWDHX40]

The book says 164 for the turbo, they can be decked to make it smooth within specs, though.
Espcecailly if it has overheated they can warp. Let us know.

 

[speedster666]

well i went out to check it but couldnt even get it started to move it in the shop it was like 14 degrees out, i tried to start for about 30 min. it did this the other morning when it was cold, but im going to try again this afternoon and check compression when its warm and cold

 

[JEFFREYCASTGSX]

To what i understood you have 90 psi in compression. To me that seems, too low. Try to do a wet compression test, because those numbers should be around 150psi.

 

[speedster666]

yea the 90 was before i changed the headgasket again and head bolts i havent check since and i was planning on if it was low still doing a wet test if it dont change looks loike i need head work

 

[Muzda]

Are you checking the compression at WOT?

 

[speedster666]

i plan on checking both warm and cold than doing the wet test this afternoon once theres room in the shop than if low im going to put a little oil in clyenders and check again.
im kinda thinking it will check out ok though once i get the car started it runs great at all temp its just getting it to start thats the problem
the first time i changed the head gasket i used the old bolts and one of them was stretched and i was loosing compression in cyl.1&2. they were leaking into eachother

 

[Muzda]

If you can, check the compression before you get it started"cold". Thats when the problem is occuring so its the best time to figure out if the compression is the cause.

 

[speedster666]

actully the problem is at all temps i can get started cold but once warm its nearly impossible it has but than again some times it just wont start at all i can push start and it starts right up but yea i can check it befor i move it into shop and ill post it all on here afterwards

I've owned 3 Talons in the past five years and I've noticed with every one of them, they have tricks to working and when something goes wrong, it's always something stupid that you wouldn't originally think of. One trick I found to get my car to start is jiggling the key in the ignition switch. Mine's a little loose and sometimes it just needs a little repositioning to get a good connection. If that doesn't help, check the battery connections. My car started dying on the highway whenever i hit a bumpy patch and at first glance, the connections seemed perfectly tight, but I'd tighten them as much as possible regardless and it fixed the problem for a few weeks. After awhile it got to the point where it just wouldn't stay tight and the terminals were replaced and glued to the battery. It hasn't given me problems since until it started freezing overnight. I haven't figured this new problem out yet, but I've noticed it'll start once it warms up to about 40 degrees.
