How are they setting the timing?
They must turn the car off, disconnect the EST wire, set the timing, turn the car off, reconnect the tire, turn the car on. The engine light will come on if you do not reconnect the wire.

Just get a distributor from a computer controlled Chevy car or truck. As long as the plug is still there in your harness you shouldn't have a problem.
A small cap HEI distributor should also work. I converted to one because of a SuperRam. The wire colors are the same for both the large cap and the small cap. Pin positions in the plugs are different. You just need to get the distriutor, coil, coil to distributor harness and the plug for the small cap distributor. Any throttle body injected Chevy V-8 will have the parts you need. I paid $50 used.
You trust the shop doing the work ? They should've been able to do what I just told you, or at least located a distributor for you.

...set the timing, turn the car off, reconnect the tire, ...
Disconnecting the battery ground after setting the timing should wipe out the SES light, too.
Did they drive it around a bit? Has the ECM "re-learned" the program? When you did the rebuild, did you do anything that would affect the timing? Like a new high-perf cam, or higher compression, or something like thet thar?
Is the knock sensor OK? They're [comparatively] cheap.
Your description of this shop does not inspire confidence... :nonod:

"can't tune it with this distributor on car."
Shure you can. Using the ECM to tune for spark won't do anything.
None ECM distrib's are tuned w/ springs and adv plates. (The old day's.)
What do you wanna do?.... Go back to the stock distrib? Just get it running?

Re: L98 Distributor (ZylaRace)
Why would you want to run an "old school" distributor with a late style setup? I would try to find the correct distributor. But if it ran fine before the rebuild, it should be simple to duplicate. Just follow the procedure that Scorp said. That is except for the tire part
If you do the "tire " thing like Scorp suggested, make sure that your tire is at the right temperature and pressure. The pressure especially affects the timing setting! I thought everbody knew that. Maybe that is why your mechanic cannot set the timing with that distributor. :D :lol: :lol: :lol: :lol: :lol: :lol: :lol:

Re: L98 Distributor (Sharky Guam)
Thanks all, this car was modified prior to me getting it, I put about 2000 miles on it, lot of road course, spun a rod bearing hence the rebuild.
The shop is a combination of computer wiz kids and an old vet. I don't know why it was changed so am reluctant to change back, it ran strong before it broke (M3 eater). with slicks on it had good speed in corners and lots grunt out of them.
Original owner out of town, so no info there. was set at 32 degrees total. it's had some minor head work, chip, exhaust etc nothing to major, just want it running again.
Thanks again
