#520 of 609 Timing a 99 gmc jimmy with aftermarket performance distributor
Mar 28, 2010 (6:39 pm)
I have been working on my 99 GMC Jimmy 4.3L Vortec engine. I put an Accel 60115 Biltech race distributor on it and the engine hesitates now indicating that the timing may be off a bit. I have also put other performance parts on it to get a bit move power and performance out of it. My question is how to time this thing now. Will it be like timing an older car? The old distributor was not adjustable but this new one is. I have two different timing marks on the harmonic balancer and canít quite figure out where to look for timing the darn thing. I know which I used for static timing and the engine starts (kind of hard) and there is no CEL on so I am thinking I am close. There really isnít anything in any of the instructions or manuals about this since the OEM was not adjustable. Other parts that have been replaced are the injectors, a ported throttle body and all the ignition stuff. I still have yet to put the headers on and a Hypertech tuner in the ECM. Anybody have any suggestions? Besides buy a new car because it will cost less than what I am doing. Thank you for your reply.

I can only assume you have the 4.3HO obdII engine.If so,I had been looking for high
energy ignition parts in Summit racing and Jeggs also. I could not find what I was
looking for because the factory distributor only has a camshaft position sensor in it. As for timing, there are two crankshaft position sensors one on each side of the harmonic balancer.Of course these 3 sensors tell the ECM when to change ignition
timing. As for the throttle body, it does not have gas flow, just air flow. The injectors
are at each cylinder under the top half of the intake manifold.You must have changed the coil and ignition module also in order to get it to run. As you said you
cain't set the timing because the crankshaft pos. sensor and the camshaft position sensor does this through the ECM. The type of distributor you used does not have
camshaft position sensor.Of course if you did get it to run right with the new parts you will definately need a new high performance Mass air flow sensor at about $300.00 dollars. I can't see it working right at all. All of the above is taking for granted you have the OBDII HO engine.I'm thinking that's all they used since 1997.
Good luck and with my factory 4.3 I can outrun a lot of V8's.Hope this helps.

We are having the same phantom lock/unlock problem with our 97 jimmy. We left the back gate open for several hours, now the car unlocks & lock on its own, whether the car is on or not...even drained the battery last night. Any solutions??

I remember finding the same problem in a GM TSB(technical service bulliten.The GM dealers service dept. gets these all the time.As a matter of fact,I found 42 TSB's on the vehicle. One was a problem excactly as you state. They did'nt issue
a recall on these problems in order to save billions.They instructed the service mngr. to fix these easy fixes when the vehicle was brought in for other work,hoping
the warranty would expire. It tells the mechanic to remove the trim off the left front door and run a jumper wire across a wiring connection. What a generic way to
proffesionally repair electronics.You should be able to bring the TSB's up on your computer.You will be amazed. But hey,I drive one too! If you can't find it, I'm sure
I have it on here somewhere so post a message if you can't. I live in WV close to where the Massey performance coal disaster happened. I know most of those guys and my twins work the midnight shift there. One is a mine foreman and he likes to
pile the work on his bro. I have'nt slept yet.They are safe.Thank GOD. So it may take a day or so to get back to you. Good luck and remember,I drive one too! LOL

I couldn't find the TSB you were refering to. Any chance you could e-mail it to me? My e-mail address is kriechatt.net. Glad to hear your boys are safe. Thanks.
#525 of 609 Fuel issue with 2000 Blazer
Apr 11, 2010 (3:21 pm)
After reading many posts about the blazers, I also have had many of the same issues...the clicking sound in the dash ( which all your info. has been quite helpful). My issue is I have a 2000 Blazer and literally EVERYTIME I put gas in it, no matter how much, when I take off the truck is very hesitant and doesn't seem to want to move too well then it will just snap out of it and all will be normal again. We replaced the fuel filter and the sending unit. Any ideas? Thanks!
