05 GT Passenger Bank Suddenly Died

[lankers]

This morning when I started my car, it ran normally for about half a second. Suddenly the car started missing terribly. I went cylinder to cylinder unhooking the fuel injectors to try to determine which ones weren't hitting and the whole passenger bank is dead. Anyone have any ideas? I've had a lifter tapping for quite some time on the passenger side (was planning on having it fixed next week). Any chance that may have caused it? It still starts, but runs like @$$

Edit: I'm not getting any error codes either.

This worries me a little bit. Mine has not started running rough or acting up. But over the last couple of months I've gotten this code (po430 catalyst efficiency below threshold [bank 2]) about 4 times. I have just cleared the code with my hand held when its happened and took a glance at the exhaust. But now Im thinking I need to take it somewhere and have it checked out. Could our problems be the same with different symptoms?

not sure. I haven't gotten any codes with mine though. I checked it with my SCT as well to see if anything showed up and no codes were found with it either. Mine happened suddenly and hasn't ran right since so I don't think it would be the same problems.

Have you checked to make sure the fuel rail isn't plugged? It's kinda weird that the entire pass side just stopes working all at once.

One of the fuses or relays for 'PCM Power' may be out. With key-on engine-off, you should be able to measure 12 volts on each of the red wires going to the fuel injectors and to the COPs. They are tied together on each side and fed power through the rear BEC connector to the engine harness.

GTKidd, P0430 is unrelated.

Thanks for the responses. I just checked all the injectors and coil packs and I get 12v to each of them with the key on and engine off. I also checked all of the fuses labeled engine or pcm and they're all good as well. Anymore ideas?

Then your injector bank wont likely be dead then. Unplugging them wont help you much, especially if the car is a little warm ( the pcm will compensate and inject more fuel to the other cylinders).
Check you maf sensor, use some cleaner to clean it, as it causes similar problems. If you have a oiled cai, this could help. Otherwise they just get a little dirty over time and cause issues.

Spark plugs and fuel filter are other options.

P0420 and P0430 are for the left and right catalytic converters

something simple to try is to swap all the coils from left side to right side, would'nt take but ten minutes and it would determine whether its ignition or fuel related. the coils are known to go out on these cars and F150's

Not four at the same time, though. It has to be something common to all four of those cylinders, like the fuel rail that someone mentioned earlier. Maybe something in the timing is bad, like it broke a tooth or something. Did you listen with a stethoscope to hear if the valves are cycling in the head?

Fuel/spark/timing.

You need all three for a fire.

Do you have fuel ? Are the plugs wet?

Pull out a COP and stick a plug in it; set it near metal and see if it archs/sparks when you crank the car over.

Check to see if the cam phaser is unplugged on that bank? I'm not familiar enough with these but if its bleeding out the mix before compression it won't light.

My guess is spark. There has to be a common coil driver.

 

[lankers]

thanks for the replies guys. One of the local mechanics I talked to said it could also be that it jumped time on that side. Where is the plug located that goes to the cam phaser? I'll give some of the suggestions a shot when I get home. Hopefully it won't be too freakin cold outside tonight.

the car had been running fine (aside from the tapping) until yesterday morning. I haven't listened with a stethescope, but you could hear the tapping more loudly on the passenger side than the left side. It sounded like it was coming from around the center of the head under where the injectors are. When the problem first started, I tried unplugging injectors because I had read that some injectors are just loud, but the tapping didn't change. Being that it was coming from the middle of the head and not the front, I figured it was probably lifters instead of a phaser or timing chain.

You should take the valve cover off. Won't take but a half hour to remove and reinstall.

Do you have headers or aftermarket cats on your car? This code usually shows up when the cats are moved and not fully warm when the car swaps into closed loop.

Sounds like the timing is out on that side. I had one do the same thing It would start but run like crap. Plugs were wet so I knew it had fuel so I checked the spark and had that. So I pulled the valve cover and check for anything obvious. I don't see anything so I pull the plugs and did a compression check. (Bingo) No compression. It actually had twisted the gear on the cam putting it off by about two teeth. Had to replace cam and gear because the pin had eating up the gear and cam.

Did you ever get this solved? I'm curious as to what the issue ended up being.

 

[lankers]

It ended up being that it wasn't all on one side. There were 3 or 4 dead cylinders all together. It dropped and bent a valve. Luckily it didn't knock a hole in a piston or damage the head too bad. It did mess up a lobe on the cam though which is fine since I'm getting new cams put in anyway. The head is still at the machine shop waiting to get worked on. They're taking their damn time though. It's been there for over a week now.
