Fwiw I have run the severe duty stuff from our local pep boys on multiple vehicles now and have had only one complaint for a squeel. He is a cronic complainer though. I have em on my truck as we speak.

The only reason I'd be hesitant to do so is because GM as a warranty company is looking for any and every excuse to deny your warranty. There is plenty of dealers willing to look the other way on stuff like this but then there is some that will flat refuse to do anything under warranty. It is...

Ok. There is a crank fuse in the underhood fuse block, 10 amp. Check that. The ecm will only power the coil on the starter relay if it see's a signal from the crank fuse. It also could be the ignition switch. God knows we do enough of them here. There should be 2 terminals with power if you...

Pepp, they can be welded. We have done a few successfully here at the shop. We did not weld them in house but they were sent out. The kennedy kit I have used and it is veyr good. FWIW

When u say truck will not start, you mean it cranks but wont run or just doesnt do anything when you turn the key to start? Two completely different things to go after.

Power service every tank. Also dump some 2 stroke whenever I remember.

Mike, check out your local dealer for the pulleys, they are cheaper than napa by a long shot. Atleast here they are. My price even list here is around 20 bucks. Just for the bearing at napa was 45 bucks when mine locked up on me on a sunday last year.

Mike, in order to remove the fan you need to remove the upper radiator shroud first, it is 2 bolts, and 4 plastic retainers, also need to remove the tcm from the shroud. Next you will need to loosen the big nut holding the fan to the pulley. Once thats loose, the main fan shroud can be removed...

Yes the bulk of the fuel comes back via the pump, the other major contributer is the injector returns. When you doing a throttled run and let off the excess from the injector bodies goes through the return tubes and back. There is no return line pre engine filter. Yes our fuel is very filtered:)

The lly or the lb7 are relatively easy to do. The lbz and up have a fan shroud that bolts to the front of the engine for some purpose and leaves minimal room to much of anything up front. I find that removing the upper bolt gives you some play up top and unfortunately the crank is best attained...

More then likely its the wif sensor. Also there is no pressure test procedure afaik. The only procedure I do it to make sure it starts and runs.

Grady, the exhaust pressure get high enough when you start to hit the mid 20's and low 30's for boost pressures. I am not sure what boost pressure the evo gives you but thats what it takes to over come spring pressure. Ymmv based on mileage and soot build up ect. The blocker plate is indeed a...

Henry, have you heard any feedback on these as far as noticable power increases over the stock vnt? I have been looking at these for some time and want one but I am hesitant based on the advertised power levels it achieves.

I wish I could just get my dam cb to function at all. Let alone the power you guys are running. :)

The injectors are obviously internal to the valve covers, pretty easy to remove. The injection pump of bolted to the front cover and it sits in the valley of the block. If you have the top of the engine removed for the injectors then getting at the pump is a sinch.

Thanks maxx, I called our shop installer and told him what I want, he told me around 400 hundred bucks and I will be remoteless with the smart start. Never even knew they had it.

Barry, as far as the trans goes, I would find a competent builder first then let them dictate the appropriate parts and build. I say so because there is a life time of support if there is ever a problem and there is a nack to the allison that most people whom never touched on wont know. As far...

In my lly tune for efi live, one of the parameters listed is IAT temp. I cant find them on the lbz stuff but they may be there and I could not find it.

Yeah, go with the napa best and press em in. They work rather well and also have the security clip so they wont fall out. Gm Just wanted to make more money on the control arms and not have to design a suitable replacement joint for them.

I would not use it. It takes a ton of pressure to move them enough to get the blocks out to remove the key so please be careful.
