mas28O Posted May 16, 2003 Share Posted May 16, 2003 I got the Lt1 to start for the first time. It runs for about 10 sec then stops. I can start it back up but it will die in 10 sec. I will have to check all of the wires. Mike Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted May 16, 2003 Share Posted May 16, 2003 your fuel pump relay should have a hot wire that is at b+ at all times -not controlled by the key.sounds like it is priming and running out of gas.you could jumper some 12v to pump to check for this.

mas28O Posted May 16, 2003 Author Share Posted May 16, 2003 For testing right now I have the fuel pumps set up to bat + direct. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted May 16, 2003 Share Posted May 16, 2003 That could be anything (I know, big help I am). My truck once did the same thing, turned out to be a clamp connecting the intake snorkle to the air flow meter came loose. Could also be a bad TPS sensor/conenction. I find it best to start simple on these things. Do a complete visual inspection first before thinking too much about cause and affect.

Tim240z Posted May 16, 2003 Share Posted May 16, 2003 Mine did the same thing the first time I started it. Try this: 1. tap gently on the injectors to make sure thay haven't gotten sticky from sitting around. 2. Unplug the MAF. Mine was faulty and it would not run with it plugged in. If you unplug it the PCM defaults to speed density. 3. disable the VATS in the PCm (if you haven't already.). 4. Check to see that the fuel pump is actually running.

Guest racerxlite Posted May 16, 2003 Share Posted May 16, 2003 Have you re-programmed your computer yet w/ the LT1 edit software? Until that is done & the theft/security is turned off, the computer will only allow the motor to be run for 8-10 seconds. I foget the web site for the software, but run a search on this forum for LT1 edit software & you should find the link. I need to find it as well so I can buy the diagnostic/error code software to further the programming of mine. Matt Quote Link to comment Share on other sites More sharing options...

Mudge Posted May 16, 2003 Share Posted May 16, 2003 VATs was disabled already... Does it run well when it does run? Sounds like Freescan may be needed, if its not wiring. Quote Link to comment Share on other sites More sharing options...
mas28O Posted May 16, 2003 Author Share Posted May 16, 2003 Mudge I Bought the cable from the link that you gave me. The cable should be here soon. I will run the Freescan and I want to order Tunercat soon. The motor runs good when it is on. Mudge put my ecm on his car and took of Vats. Thanks for all of the input. mike Quote Link to comment Share on other sites More sharing options...
Mudge Posted May 16, 2003 Share Posted May 16, 2003 If it keeps acting screwy maybe we can try a Camaro Auto tune. Quote Link to comment Share on other sites More sharing options...
