Well we never got it running. All the wiring is correct. We've traced them a hundred times. It is off the dyno stand now and we're trying to decide what to do. We could just put it in the car, but we...

Yes, I have injector pulse, verified with a noid light.

Hey planethax, did you happen to have a chance to look at my files? The only thing we are missing still is spark. We can confirm that injectors are firing using a noid light.

Thanks! These should be the latest ones.

Still not having any luck. I found this post http://www.ls2.com/forums/showthread.php?t=898910 and I'm guessing I'm not one of those tuners. I have yet to get spark.

@mrkurtis

Not sure I understand. If I disable the security codes and vats, the bcm shouldn't matter, at least this is my understanding. Could you give me more insight?

Another log, it seemed like it wanted to fire for a second. I added some more pids to the table. It seemed like the ignition voltage dropped a decent amount.

Here is an updated log. I could only find one crank related pid. Still no spark on the timing light.

Thanks planethax,

I will give that a try tomorrow

planethax,

I will try disabling those. I guess I'm not really familiar with what you're asking for. I will do some research and try it tomorrow morning. Thanks for taking the time to look and...

Quick update, I still wasn't able to get it to start. It jumped up in rpm (to ~300-400) 2 times and seemed like it wanted to start, but we still haven't seen spark using a timing light or pulling out...

Here are 2 of the logs I just recorded...the first had dtc 1629 set to 0, the second has it set to 3.

The fuel pump is being primed and running while cranking.

I should update this in case anyone else runs in to the issue. My fuel pump went bad. I purchased a new one and the problems went away.

Here is the tune. Would you suggest I grab a completely stock one, disable vats and clutch then perform a write entire again?

I will be working on it in a few hours and will post a log asap.

I will post my tune after I get home tonight. There were a few modifications already done (I compared to stock) but they only addressed pe and some tc/speed limiter settings. I should also mention...

I'm having trouble getting a ls2 from an 06 gto to start. I have removed vats and it cranks just fine. I can confirm I removed it because it would not crank with it enabled. The fuel pump primes and...

I didn't get much time to work on it, but it still hasn't been running good. In case it would help, here is the tune. It's pretty much a 6sp tune with vats and fans changed because it was...

I have a 02 Ls1 in a 91 Camaro. I posted a while back about emissions problems I was having. I gave up on it, since they didn't make me pass. It ran very well until just recently when it died on...

sorry, I didn't list was in a hurry between classes. As far as I know it is completely stock. I'm using the stock cast manifolds with a high flow cat on each side. As for which cat's I use, I'm...

Hi, I'm new here and recently dropped an 02 ls1 from a firebird in to my 91 camaro. Everything seems to run good, bu I haven't been abywhere close to passiing the emissions test here in Milwaukee,...
