2000 F250 7.3, Wont start, will run w/ spray.
I have a 2000 ford f250 superduty which has a 7.3 powerstroke. Truck has about 330k miles, and has recently begun to give me a hard time to start, and now wont start at all. When it first started doing this i would get it to start by turning the key on and off and waiting for the "wait to start" light to turn off. I would repeat this 3, 5, and eventually even 10 times in order to get it to start. Towards the end it seemed as if i could not start it unless i repeated that cycles like 10-15 times. I thought it was glow plugs, and as they are cheap i replaced them without any issues. I did not replace harnesses, but did remove it with gaskets in order to clean connector areas. Ive put it all back together and now i cant get it to start at all. I have since uncovered valve covers and confirmed that everything (injector / GP's) is plugged in tight, and correct. Ive also checked HPOP oil level and verified it is nearly full. Ive checked all fuses and they are OK. No codes. Batteries good. Tach works fine. Im kinda stumped.
I have been able to get it to run for short whiles by spraying diesel starting spray down tube. I have been however using very little because i am wary of the stuff. It runs fine with a small spray, but will die out as soon as i stop spraying. I thus believe now that i have a fuel problem. Does that sound right to you guys? Where is fuel pressure checked?
One more thing, Since i live in california and weather is currently near the 70-80 degrees. Its safe to rule out glow plugs? Ive read they are not needed for startup if weather is warm.
Any info is appreciated. Thanks in advance.
