Slammed68 Posted March 2, 2008 Share Posted March 2, 2008 After a VERY long day today.. we have FIRE!!! The actions of a VERY VERY VERY happy LS1 Z owner hearing his car make noise for the very first time!!! Excuse the laughing, but wow... talk about a rush All my problems today were caused by a Starter that wasnt hitting the flywheel, all because of a "flexplate adapter" that was already on the engine - After Great Success!! Had to take the engine and tranny out and seperate them, do the usual get mad and whine, put it all back together and in, and about 12:30 tonight it fired! Sweet!!! Wont stay running though, waiting on a couple of sensors to try tommorow, currently do not have a MAP, IAT, and O2 sensors.. just wanted to see it make noise though Quote Link to comment Share on other sites More sharing options...
HarrisonTX Posted March 2, 2008 Share Posted March 2, 2008 Thats sweet man. You must be excited as hell! Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted March 2, 2008 Author Share Posted March 2, 2008 Gotta get my buddy over here with his HPtuners because I believe the VATS system is still on. The way it shuts off so fast and so clean hints towards that. The level of excitement is pretty crazy, it makes all that work worth it.

bschiltz Posted March 2, 2008 Share Posted March 2, 2008 Gotta get my buddy over here with his HPtuners because I believe the VATS system is still on. The way it shuts off so fast and so clean hints towards that. The level of excitement is pretty crazy, it makes all that work worth it. I was wondering that too, since it doesn't stumble or choke out. Congrats on the startup, though! Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted March 3, 2008 Author Share Posted March 3, 2008 VATS wasnt on? Hmm.. time to start troubleshooting. I dont have an alternator on right now, and I dont have a MAP sensor on yet, do you guys think those two things would kill the engine that fast? The code im getting for what I believe is the alternator, is saying its a Terminal L code? P1637? Anyone ? Quote Link to comment Share on other sites More sharing options...
Bigdeezs Posted March 5, 2008 Share Posted March 5, 2008 fuel pressure ok? terminal L is the alternator...won't hurt anything. Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted March 5, 2008 Author Share Posted March 5, 2008 You think the fuel pressure would shut it off that quick? I was told I could run the stock fuel pump for a little while, thats what im running.. I dont have a FPR yet so I have no way of exactly knowing how much fuel pressure I have.. fuel pump is running though. Maybe hard wire it and see if that makes a difference? I cant tell if its running while the car starts and runs for the half second, but it does turn on and shut off with the relay. Quote Link to comment Share on other sites More sharing options...
Bigdeezs Posted March 5, 2008 Share Posted March 5, 2008 I wouldn't doubt it would shut it off that quick...The stock datsun pump probably put out around 15 psi...the ls1 needs 60psi. That 15psi you might have at the rail drops instantly when you fire it up and is probably starving the injectors. Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted March 5, 2008 Author Share Posted March 5, 2008 Hmm.. time for a fuel pump then lol.. What kind did you go with? Quote Link to comment Share on other sites More sharing options...
Bigdeezs Posted March 5, 2008 Share Posted March 5, 2008 walboro 255 I think most people use it...It cost between $90-$115 usually. Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted March 5, 2008 Author Share Posted March 5, 2008 Yeah, thats pretty much all I hear of people using on F-bodys. Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted March 10, 2008 Author Share Posted March 10, 2008 Well I hooked up a MSD fuel pump of my buddys, and the engine still did the same thing. Hardwired it to make sure the computer wasn't an issue also.. Any more ideas anyone? Quote Link to comment Share on other sites More sharing options...
