injector questions 01 f350 - help
Truck - 2001 f350 138k - stock
Ok, so I'm dealing with a cold start issue and so far I've replaced:
- all 8 glow plugs
- 5w-40 syn rotella with filter
- fuel filter
- EOT sensor
- both batteries
Next weekend I'm installing a quad gauge set up - aeroforce scan gauge (I can monitor inj pulse width, duty cycle, etc.) pyro, trans temp, boost. So when I'm doing this ill have more answers from the scan gauge. Will also change CPS next weekend
But my problem is unless I have my heater block plugged in my truck won't start(when the truck sits for more than 6 hours) or cranks and cranks and possibly starts.
From all my reading this is most likely injector problems. And most likely worn poppets. I think this is correct because the symptoms align up. The colder and thicker the oil is = poppets don't function correctly.
HERES MY QUESTION OR AREA OF NEEDED HELP - TWO PARTS
I've read that if you pull the valve covers off you can look for an oil squirt from the injector? To verify the poppet is working .... Or something along this process - can someone elaborate this and explain it correctly to me. Also to achieve the oil squirt am I simply turning the engine on and turning it over, etc?
Once I get my aeroforce interceptor scan gauge installed what are the desired amounts I want to see for duty cycle, pulse width, ..... And can someone explain what the duty cycle is looking at
Actually a third question - I'm also pricing out a new set of stock inj - most likely reman because of money but I've read that using an AD injector in #8 won't make a difference - from my understanding inj 1-7 are AD and #8 is AE the longer injector - but other members have said it won't make a difference and also that aftermarket inj are all the same size (not a longer lead one for #8) ..... Can anyone verify or give input
Thanks - I'm looking to become a DIY on my powerstroke so any knowledge is helpful
