Here is a good shot of the Glow Plug Relay to help with wiring if you change it out. 90% of hard start issues are due to a bad glow plug relay...

 

correct, i was just so happening to be replacing the injectors and decided to replace the glow plugs while i was at it.

 

Yeah I did to. And my harness just cause it was all apart. and i still cant solve my problem......

 

Thanks for the help. I hope i do that correctly to achieve my target. Keep up the good work...

 

when replacing glow plugs - be very VERY careful not to break the tip off inside the cylinder...

and yes - replace that glow plug relay if you are having hard starts... makes a world of difference! I replaced mine and she started like a champ after!

 

Thanks for the great article. I used it to replace the injectors in my truck and it worked great. A few things that I'd like to point out that may save some others some headache.

1. get a hex wrench and remove the little spout that directs the oil downward off the injector. If you remove that little spout you can easily pry the injector out with a small breaker bar. I broke the first one I did.

2. When installing the new injectors DON'T get a dead blow hammer or rubber mallet and pound the injector in. I broke one of mine doing this. I found the easiest way is to twist them side to side a few times loosening them up and than tap very lightly a few times and then twist them some more and tap a few more times until you feel it bottom out. It's very difficult to get them to seat right by forcing them straight in.

3. Replace the little injector wiring harness while you're in there. They cost around $90 for each side and the little clips on them seem to wear out and come lose.

4. When you pull the old injector out put the new one in immediately. Have the new one in the other hand when you pull the old one out and stuff the new one in there asap. This will prevent very much oil from draining into your cylinder and save lots of work turning the engine over manually later. Still manually turn it a few revolutions but doing it this way will make it much easier.

That's just my .02 from doing it. Hope it helps someone. Mad props to the OP for the article. It saved me $1500.

 

"don't worry about any fuel and oil that runs into the Cyl. i will address that later."

What should I do about the fuel and oil in the cylinders ? And how do you manually turn the engine over? Sorry for these ?'s , but I've never done this before (change out injectors)

And what are "ninja grips"??

 

All About Grip Training, Hand Grippers, and Hand Strength

also known as good hand strength resulting is a forceful grip with the fingers.

 

Great ! Thanks a bunch amigo, much appreciation for your OP ! It has helped me allot
in my first ever adventure under my VC's. After doing a search for a tool to help pull the injectors, I found this : OTC Tools OTC 6067 - Ford Injector Remover and Installer Kit
Since I fall woefully short of ninja trained grips , I am going to use this as my fall back position. Thanks again ......
