99F350 Nostart

[warlock4u]

I am having some issues with my 99 F350. It came to me used, with two bad batteries. I replaced both of them, and have had few issues until recently. The batteries were not being charged it seems, and I swapped out the alternator, as it was only showing 6v when I checked it.

I am now having the same issue. However, the new alternator is only showing .6v or so at idle, when the other showed 6v. Is there a better way to check to see if the alternator is not functioning correctly?

Where else should I start looking? The terminals are clean, and the batteries charge up just fine on a trickle charger, so I dont suspect the connectors right now.

One thing I did notice, is that the boost solenoid was clicking very quickly when I was having starting problems. I suspect low battery power is the issue here, but I am open to checking other avenues.

Any advice here?

Thanks.

Just replaced CPS, and no change in starting. I am going to check the bowl for fuel next, and all the fuses. I assume I am getting fuel, as I can hear the fuel pump running.

Checked HPOP, it was pretty empty. Put probably a quart of oil in there. No change. I disconnected the ICP, and it seemed like it tried, so I may replace that, unless there is a reason not to. All fuses look good, there is fuel in the bowl. I broke the negative terminal on the starting battery after trying to clean it, and open it a bit more. So that is going to be replaced as well.


EDIT: Found out the truck should run with out the ICP even plugged in, so that is likely not the problem. Time to try other things.

Found out the Glow Plug relay was shot. Replaced it, and the truck started right up.
