6.5 TD start up

[B Lake]

Hello,
I was a Dieselpage member in 1996-97. The 62-65-Dieselpage saved my old diesel from the scrap yard. I gave that truck to my brother in 1998 and have suffering with a gas Blazer since. Well, I just got a 95 GMC Suburban with 97000 miles on it, the Blazer has served me well but will be sold soon.

The old 6.2 diesel used to fire up instantly when the starter engaged. The 6.5 TD needs to crank over a few turns before it fires. Same hot or cold. Is this normal? I also have a question about front brakes. This is a 1500 with 8 lug rotors. How do I change the rotors? Is the procedure the same as the 2500 series? I have the procedure for the 2500 truck.

Thank for your help.

How many miles on your injectors? When I changed mine I noticed it started faster.

Many have commented that the electronic 6.5's take more revolution of the crank before start than the 6.2's (or mechanical 6.5's). Some have theorized that it has to do with the crank position sensor or reluctor wheel. Since the computer gets it's reference from this sensor, it can't do anything until it gets a signal. There are only 4 "teeth" on the wheel 90 degrees apart, so it takes some cranking just to get the reference signal. Sounds reasonable to me.

The brake procedure should be the same as for the 2500 if you have the 8-lug rotors.

I tend to agree with ronniejoe's statement about the electronic 6.5 starting. But another thing thats different is the starter. The gear reduction starter doesn't turn over the engine as fast or as quickly as the old 6.2 starters did.

Your 1500 burb is very similar to the 2500, the front brakes are the same as the 2500. The only difference between a 1500 suburban and a 2500 suburban hardware wise is the rear end. The 1500's will use the 14 bolt semi-floater 9.5", and the 2500's will use the 14bolt full-floater 10.5" rear. Thats from my observation, not necessarily the law.
