mark Posted March 30, 2008 Share Posted March 30, 2008 Who programmed the pcm? What is your fuel pressure? What fuel pump and regulator are you using? Quote Link to comment Share on other sites More sharing options...
EvilC Posted March 30, 2008 Share Posted March 30, 2008 Sounds like the anti theft is kicking in. Did you have the PCM flashed? I and a few guys were able to start the car right up and have it running without the flash. Also provide the info that Mark ask for...we may be able to help you more.

Minotaur Posted March 31, 2008 Author Share Posted March 31, 2008 Well, I got the engine from a 2002 trans-am. And, I got an after-market wiring harness. I have not had the computer flashed. I thought you were just able to plug it in and play. Anyways, I wired it up and tried to start it. The engine will start, but it will die in a few seconds. So, other than that, I think it could be the alternator voltage regulator. I plugged it in to the batery for a little while and it got hot. I talked to the guys down at Motorsport Technology Inc down here in Houston and they told me how to wire the alternator. But, I would think that the car would be able to run off the battery right? If it is the anti-theft device should the engine turn over? I was a little frustrated and decided to walk away from the project for a while. So, that is kind of were I am. What else would you guys like to know? Let me know and I can provide you with the info. Thanks a lot guys!!! You have given me hope! Quote Link to comment Share on other sites More sharing options...
Minotaur Posted March 31, 2008 Author Share Posted March 31, 2008 Who programmed the pcm? What is your fuel pressure? What fuel pump and regulator are you using? The PCM has not been programed. My fuel pressure is good. I don't know the actual pressure, but the fuel line went from soft to rock-hard. The computer actually controls the fuel pump. I used the fuel pump that comes with the JCI kit. Quote Link to comment Share on other sites More sharing options...
ktm Posted March 31, 2008 Share Posted March 31, 2008 The problem is that your PCM has not been reprogrammed. Chances are you have a few faults due to no O2 sensors, etc. and the car will not stay running. AzizaZ had the exact same symptoms when his PCM was not reprogrammed.

It was an antitheft feature on the pcm. Forgot the gm term for it but it needs to be done or the car wont start. Quote Link to comment Share on other sites More sharing options...

Minotaur Posted March 31, 2008 Author Share Posted March 31, 2008 the car does have O2 sensors. Thanks a lot guys. Who do you recommend for the reprogramming? Quote Link to comment Share on other sites More sharing options...
smoorenc Posted March 31, 2008 Share Posted March 31, 2008 I would try this link and seach around. http://www.ls1tech.com/forums/forumdisplay.php?f=7 You can also get your own software and turn the VATS off yourself. There are several compaies that sell it. It's not cheap, but if you plan on doing other things, like set your speedo, tire size, turn off the o2 sensors, torque, etc etc. It might be worth it. Also on EBAY there were people doing it for about 50.00 plus shipping. Quote Link to comment Share on other sites More sharing options...
ktm Posted March 31, 2008 Share Posted March 31, 2008 Thanks Matt. I remember reading Vin's comment about your problem and I thought it was the faults. FYI, I've repaired my front end. I replaced the headlight bucket and painted it a close enough match to my car for now. I also put the stock valence back on and installed a CF Bre spook. The car looks better with the Spook than it did with the Kaminari. Quote Link to comment Share on other sites More sharing options...
Blown77Z Posted March 31, 2008 Share Posted March 31, 2008 Jes at www.wait4meperformance.com did a fantastic job at reprogramming my PCM. Quote Link to comment Share on other sites More sharing options...
Minotaur Posted April 2, 2008 Author Share Posted April 2, 2008 Is there anything special that they have to do to the computer. I just told the guys at Motorsport technology inc to erase vats. Well, I got home plugged it in and guess what.... Same crap... So, I dropped it off at their shop for the second time... I am getting kind of frustrated with them. So is there any special programing that needs to go into the computer? Do you guys know? Could you let me know? I should have gone with Jess. That is what I get for being impatient...

Phantom Posted April 3, 2008 Share Posted April 3, 2008 Call JCI and get a reference from them. The guy they used to reflash my PCM did a great job. He took a '98 auto PCM and brought it up to 2002 T56 configuration, eliminated the VATS and some other inputs. I've had no trouble with it and the stock motor is putting out 390 HP.
