First thing: I’m really starting to hate on this wait light
History:
i bought a non-running truck, got lucky put 2 batteries in and it started right up
drove it around a little locally while I waited for parts to get it inspected
one day it didn’t start anymore.......sigh
read about the glow plug issues these have and started there
replaced glow plugs, all measured bad btw - nothing
noticed that a high pitched whining sound that was present during wait light wasn’t happening anymore (buddy surmised this might be injection pump charging the lines in preparation for start, made sense to me but not sure)
decided to investigate fuel system, specifically fuel filter
fuel filter was bad, hogged up good ( apparently there was biological crap in fuel tank that got stirred up and sucked into fuel system when I drove it around). Good news nothing got through the main filter because the water separator was clean.
cleaned filter housing and got new filters
dumped fuel tank and flushed out with clean as best as possible
broke the fuel line before the filter
added new fuel and used the primary fuel pump to flush the line till I didn’t see chunks
reattached lines, filled filter housing with fuel to eliminate air
tried pushing out air by turning engine over, eventually started seeing white smoke out of tailpipe
unfortunately whining sound was not present during wait and wait light doesn’t go out
despite numerous attempts doesn’t start
decided to break fuel lines at injectors to potentially get rid of trapped air
at all the injectors I got a pulsating drip (was kinda expecting to see high pressure squirt)
I assume the primary pump was pushing through the injector pump And dripping into the combustion chamber thus causing the white smoke but it wasn’t enough for a start
it really seems like something electrical is going on that I don’t yet understand and holding out the injectors pump thus preventing start. Have a hard time believing the injector pump just stopped working and is bad.
i understand some of this might be wrong and I’m putting this out there to get to the bottom of this. the only thing I care about is getting it started, any help would be greatly appreciated. Feel like I was pretty thorough With air purge
