580 efi help
I bought a 96 ext 580 efi that had low compression(around 70 psi), put new pistons and rings in it and and it still won't start. Its has 120 psi now, good spark,the fuel pump kicks on and charges when you turn the key, but still won't start. the little led on the ecm flashes red once when you turn the key on, then goes out. any body got some ideas? :dunno:
