I finally had a chance to talk to the transmission guy yesterday. He told me that my problem is most likely with the components that came from Global transmission. He said that they sell aftermarket parts that barely meet the specs and will cause more problems in the long run. I am taking it...

I know what you mean, I wish now I would have just changed the harness and filter and been done. But I figured with all the skid plates that have to come off and dropping the cross member to drop the pan it couldn't hurt to swap out the other components also. Guess I was wrong... Gonna take...

I have 2002 Hummer H1 that has a the 4l80E in it with 68000 miles on it. I changed out my timing chain to Leroy's timing gears and messed up the injection pump timing. I took the truck to a mechanic friend that new how to fix the timing and while he had his computer hooked up he told me the...

Took it to the mechanic this morning and TDC could not be adjusted, the CPS is bad and with the snow we had last night neither of us wanted to crawl under the truck to work on getting the CPS changed out. Gonna wait till the new power steering pump gets here next week and will change it out...

ok i will leave it there, just a pain in the ass. The starter is the original factory starter so i am sure everything is there

So on top of everything else the power steering pump is leaking. It is a new pump, but I guess when i installed the reservoir can the o-ring must have rolled. Is the bracket that goes from the PS pump to the block needed?

I ordered a new AC Delco crankshaft sensor and went to swap out the autozone CSP last night before the rain and realized the CSP cannot be removed with the power steering pump in place. I was able to pull it out enough to to look at the part number on the part itself and it matches the AC...

I talked to a mechanic friend today and it looks like his snap on scanner may be able to set/check the timing. I am going to take the truck to him on friday to try it

on the DS4 pump is there any adjusting the pump physically or is all done via the Tech2 computer

No I just unplugged it, the power steering pump is in the way of removing it

Ok I unplugged the crankshaft sensor and started the truck. It started eventually but ran rough. I plugged it back in and unplugged the optic sensor(I think) it was right in the middle of the pump and had a white lock pin on the clip. The truck would crank and just eventually barely start and...

How much 2 stroke oil to 19 gallons?

I will check the sensors tonight. What additive should i be using in the fuel? There is diesel kleen in the front tank, but just diesel in the rear tank. I am checking to see if anybody near by has the computer programs that were recommended. Leroy is on the other side of town so that may be...

Pretty sure I talked to him on the Hummer forum. He recommended coming here.

I am new here and usually hang out on the Hummer forum. I just did a complete rebuild of the cooling system on my H1 and am now getting a P0216 code with the first start of the day. I can clear the code and it will not come back until the truck has completely cooled off. Below is what I have...
