So heres the whole low down of what I've been dealing with the last couple of days. My generator to my trailers throttle cable broke so while I was waiting for the part to come in I had just attached am inverter to my D and ran the necessities off that. Done it many times before, no problems there.

Issue started because I managed to fall asleep with the D running and it ran out of gas, ever since then crank but no start. 馃槪

Sprayed some carb cleaner down the hatch and it turns all the way over, leading me to figure that maybe some crud at the bottom of the tank might have clogged up my injectors. So I did the little trick where I disconnected the fuel rail from the line, took a tube that fit snugly over the line where the rail usually connects and glued a carb cleaner straw and a washer to the other end of the tube so I could shoot the cleaner into the line and maintain pressure. Did that, kinda sounded like it cleared one or two injectors and ran more or less perfectly for the whole time it took to empty nearly the entire can (eventually my finger cramped from pushing on the spray cap, maybe 2-3 min.) Reconnected the rail to the line and checked the fuel pump relay, just in case, (swapped it out with the wiper relay that I knew was for sure good). Go to start her up and again crank no start, like she's still not getting any gas.

The fuel pump is 100% for sure kicking on, I can hear it start up when the key is turned to on. So my best guess is that either the fuel filter is clogged? Or that the pump although turning on isn't actually moving the gas down the line? Haven't actually taken a pressure gauge to it yet but after kicking the pump on a couple of times and then unscrewing the fill cap I can for sure hear that it has built at least some pressure in the system.

I really do not want to have to drop the god damn tank to even test/probably replace the pump. Does anyone know if I can get one of those aftermarket inline fuel pumps and just install that on the fuel line at the nearest accessible point to the tank and have that just move the fuel through the old pump? Or is that not even a possible way to go about this? I realize that If it turns out to be a clogged filter this won't solve the problem, but if that turns out to be the case and I end up having to drop the tank I'd rather only have to do that this one time and then in the future I'll be able to access my pump/filter that much easier.

So lemme know if you've ever heard of someone using that kind of pump or whatever other pertinent experience/information that might help me out in any way.


Side note: as I was looking at my fuse box I noticed that I can't find an ASD relay anywhere at all, there's gotta be one right? I'll attach pics of the inside covers of the engine compartment and the dash fuse boxes with the labels for everything on them.馃槙

Thanks in advance for any help/Info/advice ya got. I'll be sure to post the end result if this whole headache for future reference. (Hate finding threads discussing whatever I'm looking for that don't have any sort of conclusion to them! 馃槨)

Fuel pump was bad. Cut an access panel in the floor beneath the middle back seats. Slid the old one out, new one in. No more issues.

Glad you got if figured out & fixed!
As I was reading through your OP, I was thinking that you really needed to put a gauge on the rail & determine what your fuel pressure actually was while cranking.
I once did something similar (as you did) to one of my pickups when the fuel pump on my GMC took a sh!t. At the time it was my only vehicle & I needed it ASAP & I didn't know what kind of can of worms dropping the tank down would turn into, so I cut an access panel in the bottom of the bed.
I sure wish the manufacture-er would design better access for the fuel pumps -- it doesn't seem like it would take a whole lot of extra engineering.

Yeah no kidding. Took me a grand total of maybe ten min to make it. Would have taken about another ten to attach some sort of latch and that'd be all it took. Seems really stupid that they want you to go through all the trouble of drilling out rivets to remove the crossmember and the whole laundry list of everything else necessary to drop the tank.
