That's an obvious one I forgot about. lol Will I need to take off a fuel line in order to do so or do these trucks have a pressure tester on the fuel rail that I can screw the fitting into?

 

There is a schrader valve on the fuel rail.

 

I believe I've narrowed the running problem down to the engine being flooded. With the fuel pump relay pulled out and accelerator depressed, I tried to start it and while it didn't seem to start very easy, it did start. The RPM's go up and down when I push or let off the accelerator but it dies if I let off it more than halfway. Is the engine still somehow getting fuel even with the pump relay out? I had it running for close to a minute with the relay out and it started up again. Could there really just be that much fuel?

My main concern now is that I may have a bigger issue. There's a volcano of smoke pouring out of the manifold when the car is started (I was told there IS a large hole in it however). Would that hole cause that much smoke? If not, I'm kind of scared that coolant may be leaking due to a faulty head gasket and getting on the hot manifold causing the smoke. There also seems to be an excessive amount of smoke coming from the exhaust pipe while running and there's constantly water dripping. There's also some (not nearly as much) smoke coming from somewhere between the back of the engine and the cab. This could possibly be from fluid burning off as every line on the truck is in pretty bad shape. I do have new lines to put in and I plan on doing a lot to get this truck fixed up and road-worthy provided my engine isn't a complete pile of garbage.

What's the best case scenario for these problems? Given the state of the truck I wouldn't be surprised if it was something bad, but I'm hoping it's something easy.

 

The injectors spray fuel - when delivered under pressure. If they are very dirty or not closing properly they may be just dripping fuel - enough for you to run a bit.

Replace the manifold.

 

aaaaaah I dont think you will find something easy if it was easy the last owner would have fixed it. Injectors are extreamly dependable plus the engine is not that old. I think the engine is junk

 

Update: Two injectors were not working at all. As I was putting them in I happened to noticed a line that was duck-taped together at some point and had came apart. It's plastic and runs from the oil filler neck and goes back into the back of the engine. What even is this? Could this possibly cause these symptoms? I've tried researching but the only thing popping up is PCV. What does this hose do?

 

It very well could be the PCV. Is it attached to the PCV valve? It's in the side of the filler neck.

It can cause problems.

 

Yes, I believe it is the PCV valve. Looking down in the oil filler neck I see a small hole on the inside and there's a valve sticking out of the side with the house running from there back and into the back upper portion of the engine. Would this cause the engine to run sloppy and stall? Also, would it be feasible to use some kind of hose to bridge the gap where it's cut and clamps? I can't get the side on the engine off.

 

You can splice the hose.

Without the valve you have a vacuum leak. It should be "metered" by the pcv valve.

 

I don't think that qualifies as a vacuum leak as its only pulling a weak vacuum from the air cleaner not the intake manifold correct? On the bad injectors how did you determine they were bad not working? Sounds like grasping at straws I cant see 2 injectors just not working something caused it what maybe they were soaking in coolant for a year so why did that happen. Did you pull all the plugs and inspect them they can tell you a lot.
