2003 Nissan prairie Liberty qr20de four cylinder engine no spark was created by Jimbob
Hi can someone be kind enough to provide me with a wiring diagram of the engine computer for this vehicle please? I'm trying to diagnose a no spark on all four cylinders which has coil over plugs. I have already installed new cam and crank sensors and have 12v and ground on power feeds to both cam and crank and also to coils but still no spark. I only have basic tools like a scan tool, test light and dmm thanks for any help.
