Please Help!
 

2007 King Ranch, 5.4l, 152,000 miles. Changed plugs, boots, and springs last weekend. Truck has been running fine all week. I was on the way to the mountains tonight to take my son hunting for the week when all the dash lights came on and everything died. The truck will crank, but will not start. I hooked up a code reader and got the following codes: P0305, p0351, p0352, p0353, p0354, p0355, p0356, p0357, p0368, p0962. Any ideas? TIA

First things first, check fuses

Post the brand of the new parts you put in and why you changed them. Look through this site to find your codes. Never title a thread "Help!".

Thats why I suggested fuses

I wrote the stuff below but just noticed something odd. You said that the suddenly "all the dash lights came on". What does that mean, which lights? Was it daytime? Do you mean all of the warning lights or something else.

Anyway, here's what I had written -

I was kind of joking, because when I see "help" in a title it makes me cringe/pucker/feel it in my gut.

Apparently Ford's engineers cut their calculations close on the fuses (fuse 27), and yours are 11 years old. So Scorge's is the easy quick start. Fuses and power, or lack of, go together. I had a simple computer connector lose a single pin connection, just from being old. I fixed it by accident just by disconnecting it and reconnecting it. So, pulling and resetting your fuses wouldn't hurt either if you don't find a blown one. You could use a meter also, very quick.

Might be that that the shudder was the start of the real problem and that your tuneup work has nothing to do with it. Or that the shudder and the tuneup both have nothing to do with it. Good luck.

Double check everything that fuse is relating to...
Want to make sure that there was nothing that caused it to blow
Check for a cracked/damage ignition coil, etc.
