Well to make the story short. My engine misteriously stop starting w/o any apparent reason. Crank but didnt start. After busting my ass off looking all over, I mean ALL. Everything was good, but not fire up. Well I decided to take off the timming belt covers and found the belt shreded. I revise all components and they are good, this leave me in middle of nowhere. How that happend if all parts are good!?!?!?!?!?

Well, I found that the time was off. But how!??!!? Then, found the tensioner pulley wasnt adjusted as it should be.

Why I notify this, u may ask ur self. My engine is brand NEW crate and this happend when it shouldnt be that way. Verify the belt is tight.

Because of this careless issue from the GM tech that build the engine. Now the engine have been taken off the car to readjust the time, when the car was ready to be taken to the muffler shop and then the street.

I guess GM will repair it for you, but you're stuck with all the swapping out/in stuff. You wouln't expect this with a new engine.Good luck.

Thanks for the heads up. I'm installing a crate engine as well. This reminds me: Don't take anything for granted!

Gonna be great when you get it all working, tho. Well worth the hassels!

Where did you get a new crate TDC? And for how much? I went to my local dealership and they didn't have that engine as a crate motor.

I kept looking on the net till one popped up. I don't know about GM, but there seems to be a number of them out there. Here's one on EBay:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33615&item=2436954240

He has it listed as "`94-`97", but from the exhaust ports I would say its a `91-`95.

You have got to be extra cautious with the belt tension on the DOHC, You MUST make sure that the tensioner is as tight as it will go, witch is the point at witch the square tab on the tensioner is at the 3 o'clock position. Also, I found doing timing on the Fiero with the 3.4 dohc in it was WAAAYYY EASIER then in the GP it came out of. I don't see any good reason to pull the motor for a timing problem I can change the belt and re-index the cams in about an hour, (of course this comes from plenty of practice)

iced_theater - I got mine from eBay. The guy had 4 engines when I bougth mine. I need to look for the invoice to give you his info.

Fierobsessed - We had to pull the engine to do the cam timming. The tool I made is a bit large and dont clear the "strut base". Maybe later I can build a better one.
