Below is a comprehensive list of the frequently asked questions we receive via our email contact form.

•    Make sure ALL connections for the harness and swap have been made. This includes, Oxygen Sensors and MAF Sensor. Additionally, ensure the exhaust and intake duct work are installed properly. If any of these items are not installed correctly a no start condition can result.
•    If you are having trouble with your engine running poorly or not running at all, first perform basic trouble shooting (ensure that you are using the correct parts, see Table 2), check for faulty connections, blown fuses, disabling of VATS in PCM, spark, timing, fuel pressure, etc., then see if the PCM has stored a trouble code in its memory.
•    Contact PSI Tech Support.

•  With an OBDII scanner, check that the engine RPM during ‘Cranking’ is above 150-rpm. If the RPM is reading below 150-rpm, charge the battery. If the RPM is not reading at all, a faulty crank sensor or crank sensor wiring could be the issue. Contact PSI Tech Support for further instruction.
•  If the RPM is reading over 150-rpm, insert a Noid Light (available at your local auto parts store) in each injector connector. If the light flashes, the injectors are clogged. Remove the injectors and fuel rail from the intake manifold. Once removed insert a pan under the injectors (to catch fuel). Have someone crank the engine while watching for fuel spraying evenly out of the injectors. If no fuel sprays, or dribbles out, remove the injectors and have them professionally cleaned (soaking the injectors is not an acceptable means of cleaning) or replaced.
•  Contact PSI Tech Support to determine if Vehicle Anti-Theft (VATs) is still active in your PCM.
