One night the truck pretty much lost all power,turns out it was missing cylinder 1 through 4. I changed all the coils and spark plugs on that side,no help. Then I toyed around with the injectors and it ran well enough to limp it home,I took it to have codes read again and it was cylinder 1 and 2. I pulled all the injectors,cleaned them and changed my fuel filter and yesterday it was saying lean in both banks,misfire 1 5 6 and 8. The truck to me feels like its just struggling for fuel,but I just put in a fuel pump a couple days before all of this happened. Also the truck will start to shutter,then it stops once I put it in over drive. 4x4 also stopped engaging once all of this happened

 

Have you checked your fuel pressure?

 

Not yet,but I figure injectors,pump and filter would cover about everything.. when I pulled the injectors after cleaning it was shooting gas

 

Yea, fuel pressure (check it anyway), regulator, MAF. 4X4's unrelated unless you have a GEM problem. Anything other going on, like power windows and door locks, wiper malfunctions?

Examine the engine harness just above the AC accumulator. Look for chaffed wires there.

Has the engine heated up at all ? That could throw you into limp mode.

 

According to the gauges I haven't run hot or anything.,cleaned MAF twice,door locks never work and windows work fine. The four wheel drive throws me because I locked it in earlier in the day,not using it just making sure everything worked before I went riding that night. Now it just clicks after I try to engage it

 

May look at the gem and PCM. I would look at getting fuel to the cyclinfer first. Check fuel pressure.

 

When checking the fuel pressure,do you crank the truck or just turn it over? And what numbers should I get? I just rented a gauge

 

What's ur email. I'll send u the procedure

 

About your 4wd, just a click ? I'd jack up the front end and see if the actuator is moving back and forth from 2wd to 4wd.

Where's the click coming from, inside, down below , under the hood?

It might be something as simple as lubing the actuator.

 

I guess they all sort of click regardless, in the cab. Yea, lube up the actuator.
