99 glow plug help please

I have an early 99 (march 98 175,000 miles) and when it's cold no start.
I have never changed the glow plugs before but it looks fairly easy but I do have some questions
1)What are the best glow plugs?
2)Should I change the wiring harness?
3)Should I replace the glow plug relay?
4)Should I replace the vavle cover gaskets?
5)How much should I expect to pay for parts and whats a good source for them?
I checked with Napa today and was suprised to find that they wanted over a hundred dollars for EACH vavle cover gasket !!!

I am grateful for any help,Rick
happy thanksgiving !!!

I recommend going with motocraft glow plugs... They may be more expensive, but I haven't heard anything bad about them. My friend used to work in a parts store and he said people were always comin back in *****ing about replacing them so often. As far as the relay, I'd buy one and throw it in the glovebox for safe keeping lol. They are like $65 at my dealer. I had one that worked fine when it was like 35 degrees or higher out. when it got down to the single digits it wouldnt work. Found that out one night after work about 2am at 6 degrees. I never did replace my valve cover gaskets or uvch's either. I know alot of people are running a Stancor gpr but I have yet to try one. I've always had good luck with o.e.m parts. Im sure someone else has some input here....

go to the dealer for parts so you get factory quality stuff with no questions. i'd only replace the gaskets if you test the connectors and find a bad one. a simple continuity test will do that for you. if you are good at testing electrical circuits, you can figure out which glow plugs are bad and save some cash by only replacing the parts you need

the glow plug relay is easy to get to so unless it's bad don't change it.

Motorcraft is the way to go, what's the other brand dorsey? If you shop online you can find dealers like tousley ford that sell at a discount. I paid 10.80 a glowplug shipped from them just a few weeks ago.

If you had a van I'd say get that harness and gasket aswell without knowing the shape of yours if you don't want to mess with it, but a pickup is no big deal to find out then fix.
