Hi guys,
i will give you the whole story. a few weeks ago i bought an ET. the last owner blew the turbo and didnt replace it so his daughter could drive it on her Ps here in vic. He removed the compressor wheels and just put a bolt throught the shaft hole. when i bought it it was running fine, with a flat spot when you accelerate. i have replaced the turbo with a second hand one and at the same time took the head off to have a look at the pistons and bores, look OK. put it all back together and fired it up. idled ok and seemed to be all good. Then went for a drive. the engine wouldnt rev past 3000. OK up to 3000 but then nothing. now it wont even idle. when i turn on the ignition the fuel pump runs for about 10 seconds the stops. start it up and it the engine runs for about 3 seconds and then stops. you cant even rev it without it stalling. I had an ET about 10 years ago and remember the same thing hapening. spent $900 and didnt even fix the problem. the car came with a few spares including a fuel pump ( i was assured it was good). I have put new plugs and dizzy cap on as well. with my old ET you just gave the computer a slap and you were off again. tried this as well as checkiing all the ECU plugs. What is my next step. Any help would be apreciated.
Cheers
Christian

The only thing i can think of is an air leak.
Mental blank.

sorry about my english
this does not sound like an airleak, if air was leaking it would be heard (hood open)
possible reasons in order of "likelyhood"
- bad/loose/no connection of power transistor/ignition ground wire to distributor (when removing the head you took it off)
- head drivebelt a notch off
- bad ignition leads
- bad ignition coil
- cracked distributor cap (i once bought a new one and it was cracked off the box)
- wrong ignition timing (check with xenon, this also off after head removal)
- mixed fuel lines
- glockked fuel filter (don't remember how to spell that)
- T/B sensor lead loose
- bad fuel pump
- other wiring
- air flow meter
- bad ECU
Check the ECU fault codes from the LED:s

This is true, keep a keen eye on your boost guage.wassup393 wrote:But be careful once you've blocked it off... you may overboost before you know it, if something else isnt right.

Thanks for all the tips guys. Been flat out at work the last few days. 12 hour shifts. That and a wife and three kids at home to keep happy. should get a chance to look at in in the morning. night shift tomorrow night. The excess boost valve, does it vent from where the top meets the sides. if so would a piece of rubber bike tube stretched over the top of it work to test it. it could still vent then. and would make it heaps easier to check?
i will let you know how i go. Oh yeah the ecu is not showing any fault codes. can i asume from tis that the ecu is OK. or can they shit themselves without any error codes.

problem
hey i had the samething, i screwed the dignostic screw on the ecu in and run it and mine stopped. turned out to be the ecu, might of been faulty. plus i dont have the overboost valve, all mine was doing was wouldnt rev over 3000rpm or when turbo kicked in, i checked for air leaks, fuel problems, etc but when i run it in dignostic mode it stopped, turned the screw back and bob was my uncle.
hope you sort it out, or it just fixes itself out without much trouble or problems
