LS3 GMPP E67 controller engine wont start
Hi everyone, :hi:
Having a some trouble here and need some help. I just swaped a 2008 LS3 corvette engine into my 1999 Chevy S10 Blazer mated to a T56 6 speed manual, using a Brand New GMPP E67 LS3 engine controller.
Here's the problem, I start the engine and it will start for 3 seconds RPM's go up to 2000 then down to 1000 and shuts off. After it shuts off it wont start again. I check the injectors and with a noid injector light and no power to the injectors, I checked for spark and no spark. I check the fuel pressure and its always there from 56-60 PSI when it cranks. I can also hear the fuel pump when it's on.
So now I don't have power to the injectors or spark. there is something inside the ECM shutting it off. the only way the engine will run again is if I disconnect the battery for a few seconds reconnect it and then it will start again and shut off after 3 seconds.
when the engine runs I see the noid injector light go on, but after the 3 seconds it shuts off and I try cranking the engine again the noid injector light dosen't light up anymore.
This GMPP E67 ECM does not come with VATS as an option, I thought it would be VATS too. There is no VATS here :shrug:
Also my factory guages work, the RPM's work and the Oil Pressure guage works
