How much does it cost to change the ECU on a LS1?
If you don’t do this, the ECU won’t turn the car on until it sees a signal from the factory key turning in the factory barrel. Along with the modified wiring harness, Scotty was pretty much all done on the electrical side of the project for almost $1500.

What are the most common problems with LS engines?
This article will be split into the most common problems faced by LS engines during their lives. Statistically the most common problem that presents itself even to fairly new engines that are unmodified and even more so in older engines that are modified is hydraulic lifter failure.

What causes a car starter to not turn over?
The most common problem with a starting motor is, when you turn your key and nothing happens. A solenoid or motor that has burned out or electrical issues, may cause this as well. Furthermore, a dead battery can cause the same problem. It may appear that you have power to your starting system, but the engine will not turn over.
What happens if one spring breaks on an LS engine?
The advantage of dual spring is that if one spring breaks then the other spring will hold the valve up and prevent it dropping into the engine. If a single spring breaks it is common for a valve to be dropped which causes a huge amount of damage. Sometimes the valve is held up by the valve locks and the spring is just collapsed.
Can a blown fuse cause a starter to not start?
Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
How to test a 5.7 Liter LS1 swap?
You can test your injector and the harness using a fuel injector noid light. The part number we’re going to be using for our 5.7 liter LS1 swap, is BOSCH 510597 or 510587.
