Question

replaced engine from 97 to 99 flywheel looked the same then no start no spark no codes replaced complete dist, crank sensor, all connections, still no start disconnect all sensors for codes had all but crank seems no opens in wiring don't get it

Answer 1

The flywheel the same for a 97 to a 99, so that okay there, But the Crank position sensor for a 97 is different . For a CKP for a 97 from Beck Arnley the part number is 1800465 and a 99 CKP from Beck Arnley is  1800589. The connection will be the same but the specification are different
