Light the ***** on fire.
Ever had one of those times you couldn't figure something out and you wanted to do just that? Well, I was having one of those moments, but didn't literally want to do that, but ended up doing it anyway.
Bought an old Ranger off a guy that was running when I first saw it, wasn't running when I got it. I expected it was gonna be a toughy, but I went into it as a "project". Truck sat for a year, so the gas was bad. Changed out the fuel filter, dropped the tank, pulled the assembly and replaced it and the fuel pump. Replaced the coil pack, verified I was getting spark, fuel pressure on the rail. Just a matter of getting the bad gas out that was already in the injectors and engine. Got a friend to turn it over while I poured half a can of Seafoam through the brake booster vacuum line and kept cranking it over. Got it to catch a couple of times but nothing solid. Kept adding Seafoam. Now on older carburetor engines and small engines, I'd just splash a little gas in the carb and get it going. Being this is fuel injected I didn't think it would work the same way, not to mention that the throttle body on the 2.9 isn't very oriented to do it. Figuring what the hell, I pulled the air filter tube and splashed some Seafoam straight in the port. It ran for a second then died. Did it a couple more times for the same result. At wits end, I finally just took a funnel and jammed it in there and bent it up, and dribbled some gas down through the port.
Ya'll know where this is going.
She ran like a demon for a few seconds after, then backfired, and well, the ***** lit up like a match. Whole engine compartment was on fire. I pulled the still flaming and melting funnel out and threw it on the ground while the other guy ran for a hose. By the time he got back I'd already gotten the flames out. I've had small engines and carb's backfire before and pop some fire, but never had anything like that. It didn't damage anything, just burned the gas off and lit the grass under the truck on fire. One of those things that's hilarious to retell, but pretty crazy when it happens.
After letting it sit for a bit, I went back to cranking it over, and got it to run kind of with the starter "running" the motor. Adding more Seafoam through the brake booster vacuum line it finally caught and roared to life. Ran it wide open for about 15 seconds to make sure it stayed running, then kept it about 2K for a couple minutes, adding the rest of the bottle to it. Let it idle down and it ran like a top. Just had to get the bad gas out. I'll probably tear the intake off and check the fuel injectors soon, but I got it to run finally. Thought you guys might get a laugh out of this, I'm laughing now, but I wasn't then.
