Happy Independence day to me! Go to fire the truck up to head out for the day, turn the key, injectors buzz, crank it over, it pops once. Literally just one "pop" and then nothing... cranking and cranking and cranking and nothing. No smoke coming out, so the injectors are not firing. Didn't have much time to mess with it, but I figured I'd document it here anyways. Helps keep me sane. Had to take the gf's escape around for the day and her A/C doesn't work properly of course... wonderful!
Got back late last night but messed with the truck a bit. To me, the one pop and then nothing was a little odd. I checked ALL of the fuses under the steering column, all are good. I swapped FICM's, no dice. Hooked the laptop up, started monitoring a few things. I really need to go buy AE, because this software I have is goofy. It was giving me all of my ICP readings in metric first. I messed with it a bit, finally got it reading in English units, but now it's giving me actual ICP in ft/hg, instead of PSI, but it gives me desired in PSI. I had to do a conversion after I brought it inside. It appears IPR is going from 15% up to 75%, in an attempt to get it to fire. ICP actual, comes in around 1500psi as I crank, and desired seems to be going up to 1000psi or so. Odd that actual is higher than desired, but I'm not convinced it's a high pressure oil issue. I didn't get to check anything under the hood as far as relays/fuses. I was VERY warm and had been sweating all day and didn't want to deal with it. It might even be as simple as the FICM relay. What WAS concerning to me... FICM SYNC. Didn't appear I was ever getting a "YES" there, always appeared like FICM SYNC was just not working. FICM SYNC is the camshaft position sensor and the crankshaft position sensor telling the FICM when to fire, correct? Without SYNC, the FICM doesn't work. Which makes sense. I'm hoping just a simple FICM relay. Kind of odd how it went out, but I guess I should be happy it didn't leave me stranded somewhere else and did it in the driveway.
Also scanned, no codes, and no check engine light.
thoughts/comments/laughter welcomed.
Also, I am running a vegistroke, which is about 1/2 on 1/2 off the truck right now for maintenance and cleaning (been this way for over a month) The only part of the system electronically that could potentially interfere with the truck running is the splice into the stock fuel pump. Basically you take the power supply to the factory pump, and cut it, then splice a wire on each end that run to the vegistroke and to the pressure switch. Basically once that pressure switch sees enough pressure of WVO, it shuts the stock fuel pump off. With the system off of the truck, there is a jumper plug installed, to reconnect the power to the factory pump permanently (at least until the system goes back on). I turned the key on the truck and when I get down there, I can hear the pump running (I'm 90%) sure. It's hard to tell with the darn vacuum pump running non stop though, so I will try again today and crawl under there and feel the diesel pump to make sure it's pumping. It's a fairly new pump so I'm sure it's good. All fuses on the vegistroke brain are good too. I am almost certain this has nothing to do with it, more pointing it out before someone asks about it...
