Founds this issue.... Ran the car wiothout the little timing spout in at the track. He set the timing back to run on the motorwhen he got home, shut the car off reinstalled timing spout and car would not start. Like it had no fire. Pull the spout out car will fire right up. Any ideas, Tried different A9L same thing. Module , distributor (pick up) issue?
What did he set the timing to when the spout was out? The EEC expects it to be set at 10* BTDC, a few degrees either way won't make that much difference but the EEC calculates the timing assuming that the base is 10* and then ads the amount that is necessary to achieve the timing in the tables depending on load, rpm, ECT and ACT. When you pull the spout, it locks the timing at whatever you physically set it to. If he set it to say 20* at the track, as long as that spout is out, it will be running 20* at all loads and RPM's. If he put the spout back in then the EEC will be adding an extra 10* everywhere because it thinks the base is 10* when it is actually 20*. It could be pulling or adding too much timing and doesn't want to start.
