1998 lsvtec timing problem
ok so i have a 1998 teg that i did an lsvtec on and im having a bunch of problems getting it to time. its a b18 with a garrett turbo and its a build botomend with 8.8:1 weisco pistons. i set the timing dead on and it wont even try to start. i retard the timing about an 1/8 to 1/4 of a turn and it will start with the throttle about halfway open but wont stay running have to keep it revved up to run and it still sounds like crap. the timing keeps moving around on the crank and im not sure why. im not sure if its the gear on the crank or what but any help would be appreciated
i set it to TDC and it wont even try to start if its advanced a bunch then itll run but it wont idle and doesnt sound very healthy. and when i say retard i mean by moving the crank and leaving the cams to #1 on TDC
ok so i just foundout that the mark on teh crank gear is off. i put a rod in cylinder 1 to see where TDC is and was about an inch to the right of the mark. motor runs better nnow but still sounds like a miss. its firing on all 4 i think now cause i check the manifold with a heat reading gun and they were all within about 10 degrees. i had dan benson do the block and the head was resurfaced but he didnt have to take very much off.
but the marks on the cams fit in with the holes on their covers and i put a new mark where TDC is on the crank and it isnt jumping teeth or anything. what is the chance that its the tune?

well it has the tune that was on it which is a street tune so yes. i have a hondata that im going to use when i get a dyno tune on it and i was going to mess with that a bit but i dont have the cord for my laptop. there is a possibility that it could be the tune and im havin my tuner come out sometime this week to check it out but he said it should still run on that tune. thanks for you help btw
just foundout that the block and head werent grounding correctly so it runs great now just to much fuel pressure! so im gonna turn that down and see if it idles
i talked to a tuner in servian in colorado springs ang they think it could be the map in the tune also im wondering if my injectors took a **** on me and are just sticking wide open?
