Poor Starting
I have a 1988 F250 and I am having some trouble on starting first time in the day. It has been warm in the day and the nights are mild at the moment. I am having to try 2 or 3 times before it will start but once it has done a couple of miles it will start straight away. After the intial difficult start there is a little bit of grey/white smoke which soon clears. Could this be flooding? I wait for the light to go out and the clicking to stop before I try to start.
Any ideas would be appreciated.

mine was doing the same thing. turns out seven out of eight glow plugs were bad although they were replaced by the guy I bought it from 3 months ago before it became mine. I know it was done as I helped him do it. He liked to use ether when it wouldn't start right up and it fried them. Replaced them and not a problem since.

my 89 also starts hard. I changed all 8 glow plugs 2x. I put in Champion plugs and then found out that the Motorcraft/beru plugs are MUCH better to use. So far I have changed plugs, fuel filter, injector return lines and installed a 2nd battery. The truck will roll much faster now, but my gp light will only stay on for 4 to 5 seconds and a cold start will take 2 or 3 tries. A warm start will fire once it rolls for 5 or 8 seconds. A HOT start (hitting it after being shutoff for only a few minutes) will fire right up, maybe roll-over 2 or 3 times. I am getting a little discouraged with this thing, but I have to keep at it, this is my winter truck. Any help would be greatly appreciated.
If anybody is interested, I have a total of 10 good glowplugs for sale or trade. Cheap.

the gp relay is behind the air cleaner, mounted at the back of the intake. It has a plastic cover over it. It is pretty simple in design and performs much like a starter solenoid. When I first got my truck, it would just click like crazy. I found and replaced 1 bad glowplug and the relay worked kinda like it should, only problem is, it only stays on for 4 or 5 seconds. There are some great threads on how to test and rewire the controller, just do a quick search on it.
