Hey Fellas installed a 1.0 on my 85 Vette.. car went to shop to get EMI fixed, when I picked up it ran great 00 in the info screen drove it for 2-3 days and parked it for paint... battery went flat after I left hood open, I replaced with a new battery same size and CCA now it won't start. Battery tested good, getting a rpm signal on tach and handheld while cranking. TPS is showing 0.. Fuel pressure @43lbs and I've verified I have fuel. but the injectors are not firing and there is no Pre-squirt?? system is coming online fine just noticed I'm getting a 02 error and flashing ECM about 30-40 seconds after I power the car on? (is that due to low voltage?) Cranking the voltage drops too around 10v?? Plzz help before I have to send it back to the shop!!
