Owner's manual is free to download at www.fleet.ford.com under MAINTENANCE.
It will have the location of the inertia switch and shoulld have the fuse/relay panel layout.

When you turn the key to the ON position, you should hear the fuel pump prime for a second or 2. If you don't hear that, your problem may be fuel related. Possibilities include; FP relay, inertia switch, or the fuel pump(last thing to try).
Also, I think the cover to the power dist box should tell you which relay is for the FP. If not, here's a link to diagram for it. http://autozone.com/servlet/UiBroker...3d800ba8f3.jsp

The cam sensor will not cause a no start condition. It may take several attempts, but the engine will start and run with a bad cam sensor if there are no other faults. In fact, you can disconnect the cam sensor completely and the engine will still have a 1 of 3 chance in starting for any given attempt.
A faulty crank sensor (among many other things) will kill the spark.

Bad CoilDist. Pack??? Any codes??? The money spent on a OBD II code reader is well worth it. I found one at Wal-mart for under $100.00. Works on other than Ford also.

What make/model code reader did you buy, and do you know if it works on Toyota as well? I bought one from Harbor Freight a couple of weeks ago and it worked on Ford, but not Toyota. Took it back.

Well, I spray the screws with some lubricant to make removal easier... and when a friend went to check my codes with another style code reader,it started.....I am still going to change this out... but the one screw that is visable,is seemingly rounded off... what size is that screw? any suggestions on how to best get at it with the limited space? Thanks in advance...mike
