It should just work its-way in, but you may still have a fuel issue it when you spay starting fluid and it fires off. I would check for power at the injectors first. If there is power there then should do a fuel bleed down test. With a fuel pressure gauge hooked up build up pressure by cycling the key on, off...then with the key off watch the fuel pressure to see if it drops more than 5 lbs in 3 minutes. If it does then may have leaky fuel injectors, leaky spider lines, or a leaky fuel regulator.
