Here is the story it started when the check engine light came on during a rough cold start but truck seemed fine in the mean time ordered the OBDII scanner, one week later it died while leaving driveway(day before scanner came in) and refuses to restart. Scanner codes were P0300-303 which are cylindar misfires. The codes have been cleared and it reads no new codes but of course truck wont restart to get a good read. We have spark and fuel, changed plugs which were wet with fuel. We are at a lose we have checked about everything she just cranks ans cranks but NO attempt to actually start...any suggestions welcome.....

 

Start with testing the fuel pressure since you say the spark is present .

 

I briefly mentioned above we have fuel thats fine...we are now leaning toward timing chain which is fine with me because that will be covered under recall.....
