Car starts and dies?????

[Eclipsezeke]

OK background: I let friend borrow car He bent my valves. No Block or piston problems barly nicked piston... Took Head to machine shop got work done.

the prob: After reinstalling everything im 99% sure i got the timing right and when marks are lined up cylindar 1 is TDC.. OK HERES THE DEAL WHen i start the car it starts up like a champ.. but once it gets to the normal idle spot it dies like 3-5 secs after it starts its not a sputter dieing its like as if i shut the engine off with key. once in when i started it it ran for about 2 min then i tried to give it little gas it choked out and died..

Idk what it could be i checked the forums and tried few things that sounded around my prob but nothing.. is there something i coulda missed to do? or check? please help me out

Is the car stock? If it's modded, list your mods. Double check your fuel pressure, TPS, throttle body, and check for boost leaks.

 

[ALLBoostAWD]

Check to see if your MAF is hooked up. I did that with my 1g once, and it did the same thing, start up, CEL, then die.

cAR IS COMPLETLY STOCK.. IM SURE ITS GETTING FUEL. wOULD BOOST LEAK STILL MAKE CAR SHUT OFF RIGHT AFTER START EVEN IF NO BOOST WAS PRESENT?

 

[dsm_racing]

It would have to be a bad one. (Like a pipe totally not connected.) Double checking the maf connection is a good idea. I didn't think of that.

Ok well i checked mas and everything, how i check for bad TPS? and on the exhaust manifold where it bolts to the turbo im missing a bolt which i forgot causeit stripped out could that be a big enough leak if its leaking at all the other 3 bolts are in and tight.

 

[c4uldr0n]

having 3/4 bolts will only cause a leak to the turbo... not a boost leak...

here is a link to check TPS (and many other items) on a DSM: http://www.geocities.com/motorcity/downs/7678/dsmtests.html

Check you throttle body again. Make sure you don't have a plug not plugged up. Check the wiring harness good to make sure you didn't miss a plug.

OK ill check again, what am i looking for on the TB? and i am gonna go to schucks and rent a OBD reader to see whopefully that will tell me something ill get that in the next 3hrs so ill let u know what it says

A bad/disconnected cam angle sensor(cas) will give you a start & 2-sec run-& die symptom with a code p0340 in the memory - check it out, it happened to me before . . .

 

[Eclipsezeke]

oK FOR THE OBD2 READING IT SAYS P0340 CAMSHAFT POS SENSOR.. DOES THAT MEAN CAS IS BAD OR WHAT ANYWAY TO CHECK IF ITS BAD OR NOT?

 

[Eclipsezeke]

Also if it needs replaced can i use 1g cam angle sensor also? for my 95 it just seems easier to use that then taking my cam sprocket off and putting back on. if it isnt as hard as it looks let me know thanks.

 

[Eclipsezeke]

OK update i reset the code and started the car started right up then when was idling was idling not normal. and alot of motor shake. and alot of gas smell is this all cause of bad CAS? car stayed running till i turned it off and tried to restart it then it pulled the P0340 code again but not till i turned it off and back on. thanks for any input

 

[poonman]

ok well anyways considering that you have a IAC sensor i would check that considering that everyone forgot to tell you that the IAC IS THE CHOKE of your car

Also touch the pipe coming from your EGR valve, if it burns you then guess what your EGR is stuck causing you to run like crap

and here this if for you, i have alldata

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1.....
So i go down stairs and fiddle with my car again... still cant find anything wrong im running outta dollars so i get fustrated and fed up and hit the intake cam with a hammer... not hard to really dmg anything... i start packing my car with stuff cause im gonna get it towed i sit in it to listen to the radio and i decide to start it up and WTF it starts up and idles fine and drives..... WTF to funny idk what it did but the cars drives fine now no more p0340 code either hmm

 

[dsm_racing]

I would start looking for a new CAS. Sounds like yours might be on the way out. Glad to hear you got it going. Good luck getting it home.
