It also think it's going to be pretty tough to test for leaks if I can't keep it running?

 

Ok tired this since it isn't running:



Used a cigarette to search for leaks, couldn't find anything obvious and the shop vac blew a circuit breaker because it sounded like it was clogged.. so I can't detect any major vacuum leaks with this method. Any other ideas?

 

I just watched your video. It's hard to tell, but do I hear a clunking metal sound when it drops to low RPM's?

I'll admit that I'm kind of just guessing at this point, but here goes:

-Were you deep enough in mud that your exhaust could be clogged? When you start it up can you feel exhaust pressure at the tail pipe?

-Have you double checked the CPS to make sure you didn't get any debris or oil in the plug, and the plug is snapped in all the way?

-have you changed the oil and filter since you got it out? Did it look like water got in?

-Is there a seized pulley holding the drive belt?

-Are you sure you got the ECU installed correctly?

 

All reply's in red

 

I remember you said you changed the CPS, I was just making sure that you got the new one plugged in all the way and snapped into place. It's also easy to get some type of debris in the plug when you reconnect it so I just wanted to double check and make sure everything looked good there.

You can just take the belt off and try and start it. Just don't let it run for a long time without it or it will get hot.

 

Did you replace most stuff at once? Or one thing at a time? Did you replace with new or used? Did you keep your old parts?

I asked all that because many years ago while back at home visiting I replaced the distributor, plugs and wires on the farm Rover. On startup it ran like crap, like it was running on one cylinder. So I figured I'd screwed up the distributor install. I messed with it for hours, couldn't sort it out and had to leave to go back to school. This went on for a year, every time I was back home I'd spend hours and hours with it. Finally, one time, out of desperation I installed a set of new plugs my dad had for his Toyota Corolla and it started right up and ran smooth as silk. It turned out 3 of the 4 brand new spark plugs I'd installed were bad.
I learned that day to never assume a new part can't be bad and to replace as little as feasible at the same time.

 

I did each part one at a time. I started with the Air, then moved to spark, then started the IAC and CPS ( it did run for a while after replacing the CPS but I was never able to floor the gas). Then as things went down hill I started on the fuel system. I have all of the original parts and have tried swapping things around trying to isolate. Going to try without the belt today.

 

OK, took the belt off, no change. We can rule out a ceased pulley. Now the joys of putting back on

 

How high was the water level where it was sitting? Was there any heavy rain while it was there that might have raised the level while you were gone then went back down before you got back to it?

 

When I opened the driver side door water came in, it was not much but it was just at the door level. Over the next 5 days we had zero rain and 90 degree temps so the water actually dropped about 4 inches in the mean time making it easier to get out. As per your advice I tough maybe I got a bad batch of spark plugs so I bought another set of 8, no change. What the heck is the box under the center of the truck the fuel lines run into? I can't find it in the RAVE?
