I'm at a loss again. Here's what I'm dealing with. 93 4.0 in a 87 Bronco ll. Vehicle sat for a couple years before I got it. Today was on my way down to DMV for title change stopped for some fuel ran in to pay went to start it up and it just spun over. Pushed it out of the way to the curb and let it sit for a few as it's had this issue before but usually starts right up but runs rough like it was flooded. Today no luck so I sat thinking "It'll start" but not this time. Started doing some checking had some fuel pulled a couple plugs and they were soaked. Called a neighbor who came to get me so I could get it towed home. By the time we got it back about an hour had elapsed from finding it was flooded. Jumped in and tried to start and it did. Ran just like a flooded carbed car does. Started doing a little more looking and testing after it cleaned itself up. Checked fuel pressure with only key on was at 10# then started it up and she went to 39#. Let it run till temp came up and shut it down. Still at 39# for about 10 minutes then started to drop. Dropped 10# in 30 min and still dropping. My guess is that I've got some injectors that aren't shutting off or sealing. When it was running pulled vac line off at FPR to see if that was blowing fuel out but nothing came out and line was dry.So far I've replaced in tank pump and frame rail pump fuel filter in line resivour without filter as the one that came off was. I can't figure any other way that fuel would get to plugs other than injectors especially if FPR isn't blown.
I'm at the point now of pulling it apart and send the injectors to be tested and patterned. Not a big job but any other other ideas from you all before I do?
Another thing it's been doing is that the idle in the am is normal about 800-1000 but when I get to work about 40 miles later it's up to 1500-2000. I've replace the temp sender for gauge single wire and ETC 2 wire for computer and factory 195* thermostat.
Mileage hasn't been great either about 17-19 but I can live with that. It's alot better than 6-9 my 72 Chev gets.
Looking to hear what you all have to say and think.
