Truck will start after 20 or so tries
I am new to this group but hoping you can help me out. I have a 2000 F350 7.3 Powerstroke with 133,000 miles on it. In the last several months it has been a very hard starting truck. The temperature can be 60 degrees out and I have to cycle through the starting sequence up to 20 to 30 time to get the truck to fire up. If I get it started and run it for an hour or so, it will start up again as usual, but left overnight the problem begins again. I have changed the fuel filter and that does not seem to help. The CPS, IPR, and HPOP are original to the truck and never changed. The only modification made was a set of gauges added. The tach stopped working 5 years ago and I have not changed the instrument cluster to fix it. It does blow white smoke when it does fire up.
When I turn on the key the WTS light comes on and I can here what sounds like a small pump humming or pressurizing, this continues for a minute or so after the WTS light goes out. Once the sound is gone, the there is enough power in the batteries to spin the starter. After the first round of trying, the small humming sound goes away and all I wait for is the click to tell me the glow plugs are no longer taking power. Then I try and it cranks fast but no joy on the start. After many tries it suddenly pops off and runs fine. My wife does tell me she thinks there is less power going up grades than there used to be but it never falters once it gets started and runs.
Any insight would be greatly appreciated.
