2003 Lincoln LS 3.9L 160xxx+

Hey guys I'll kept this as short as possible. Had a rough idle so I changed coils and plugs. Broke a bolt off in valve cover so had to remove valve cover and remove broken bolt. Replaced valve cover gasket and put it all back together. Problem...how do I get the oil indicator tube back in the hole, is there some special trick?
Second question, do how does the fuel system prime up? I tried to start it and it's just turning over like no fuel or no fire or both..

I used Motorcraft plugs and coils, and felpro gaskets.

Any comments are greatly appreciated!

This is my first post for help so if I didn't do something correctly please let me know
 
Heading back out now to see if I can get it running! Thank you so very much joegr!
 
Well I got the dipstick back in and I'm getting fuel to the fuel rail. Still won't start. Engine just keeps turning over. I don't know, never thought removing a valve cover would keep my car from starting...any ideas?
 
Did you damage the COP wiring and maybe blow the fuse? Did you flood it? (Hold the pedal to the floor while starting if so.) Did you check and set the gap on the spark plugs. (Yes, they are pre-gap'd, but at least some are almost always wrong. All need to be exactly 1.0mm.) Did you damage or fail to reconnect any vacuum lines? Will it start if you disconnect the MAF sensor connector?
 
Gapped all plugs at 1.0mm...I'll have to check the fuse, is it under the hood or inside the car? I never tried the unhooking the MAF sensor, but will try it shortly...I'm pretty sure I got everything hooked back up, and I don't think I've damaged anything but will double check.
 
That fuse is in the fuse box at the front right, under the hood.
 
Nothing was blown...and it wouldn't start with MAF sensor unplugged....I pressed the pedal all the way down and still nothing...should I just throw in the towel and take it to a mechanic?
 
I doubt that having a towel in there would help. In fact, one has caused trouble before.
As for towing it to a mechanic, that depends on what tools and skills you have. Either you aren't getting power and pulses to the coils and/or the fuel injectors. If it's one or the other, but not both then it's not too hard to figure out. If it's both, then it's time for a good scan tool to see what's up with the PCM.
 
What tells the coils to fire?

They are all controlled directly by the PCM. It uses information from the crankshaft sensor and the camshaft sensors to know when to fire each coil, as well as when to open each fuel injector. Of course, most of the other sensors play into it too, to one extent or another.
 
It ran before you did the work, and doesn't run after? Recheck your work, you almost certainly forgot to reconnect something important.

yeah it didn't run good but it would fire up....I'll check it and see where I may have messed up....
 
I've caused myself multiple scares with the 10A COP fuse. I've also run the V8 on 5 cylinders accidentally (a case of forgetting some plugs).

You're missing spark or fuel. Are all coils plugged in? Did you really check every fuse? Do you have a bluetooth OBDII scanner to help by reading pending CELs?
 
Ok so I broke down and just took it to a mechanic and the said my fuel pump wasn't making enough pressure to fire my engine. Turns out we had bad gas so they replaced my fuel pump filter, cleaned out my gas tank and replaced the fuel and it's running perfectly now. They said I didn't miss anything putting my car back together, thankfully. So my question now is, are there two different types of fuel pumps for my 2003 LS? It was made in July of 2003, and the local autoparts stores only showed one made for man. date of November 2002....the cost difference was about 300 bucks
 
there are two different fuel pumps... one on each side of the car... one pump pumps gas into the other side of the tank and the other pushes the fuel to the front of the car. its due to the shape of our "saddle" shaped gas tank
