New to form. I got a 50 Commaander Iâ€™ve put an Art Morison frame under it and to GM kit whit the LS3 480hp and trans. Hereâ€™s my issue. Drove the car about 20 miles shut it off got oil for the first change came out car would not start popped the hood looked for something off or lose no luck tried it again started right up. Drove it home let set for about ten minutes no start let it cool off a little started right up. Showing no codes This is a new build first time out. Iâ€™ve had the car running in the shop and no issues. It turns over and can hear the fuel pump come on. Iâ€™ve got three years into this build and ready to go for a long drive. Iâ€™m not new to EFI as I have a 66 Chevy 2 with a 401sb with a 510 Whipple on to with a Hilborn injection using a Holley HP ECU. So anybody got a clue what Iâ€™ve done wrong??
Can anyone hook me up with a wiring diagram. Thereâ€™s a lot more wrong with the wiring than I thought. The guyâ€™s that wired it did the worse job I believe Iâ€™ve ever seen. Iâ€™m going to have to start at ground zero. So I need to know where every goes color and so on. Iâ€™m so made now I can hardly control myself. Iâ€™ve seen bad wiring jobs before but theses guys take the cake. Any help would be appreciated. Someone tell me how to post pictures I'll show you what I'm working on [/img]
Ok hereâ€™s where Iâ€™m at. Dead short at the ECU. Replaced the Hot wire still there. So Iâ€™m guessing a sensor. So next day I can get out there Iâ€™ll start unplugging one at a time still I find it. Anyone have a clue where to start. It would start fine but drive it and shut it off let it set s few minutes no start. Cool off a little start right up. Now will not start at all. Blows the fuse on the 12v.
Well got if fixed at last. Pulled the control box off to see if there was something causing the issue. Well, one wire on the bottom had a bad nick in it. Fixed that and bam it's done. It looks like when they pushed it on the bracket they were not very careful doing it. So everything is working lit should. I have not tried a hot start will tomorrow. Got family things to do. Thanks a lot for the help.
