May have found something.

Quote:
Performing any of the following repairs may require you to initiate a computer relearn procedure in order to restore proper vehicle operation.

Powertrain Control Computer replacement with a nontransferable PROM
Powertrain Control Computer reprogramming
Body Control Computer
Instrument Cluster replacement
Engine replacement
Crankshaft replacement
Crankshaft harmonic balancer replacement
Crankshaft position sensor replacement
Diesel Engine controller
Diesel engine PCM with or without injection pump replacement
Diesel engine front cover replacement.

Here are some helpful tips to perform the system relearn, depending upon the particular repair that you have performed.

Powertrain Control Computer Replacement with a nontransferable PROM

All computers being replaced must be reprogrammed or “reflashed”. This is so the replacement computer has the most up-to-date information for that particular vehicle. This information is specific for the vehicle based on the vehicle identification number, and cannot be used on another vehicle, even though they may appear to be similar. Relearn procedures involve: Crankshaft Variation (CASE Learn), Engine Idle speed, Theft Deterrent password, and Transmission adaptive shift points.

Powertrain Control Computer Reprogramming

If diagnostics reveal that a reprogram or re-flash of the computer is necessary, relearn procedures involve:

Crankshaft Variation (CASE Learn), Engine Idle speed, Theft Deterrent password, and Transmission adaptive shift points. Body Control Computer &/or Instrument Cluster replacement Theft deterrent password relearn is necessary. Engine, crankshaft, harmonic balancer, and crankshaft position sensor. If any of the above items are replaced, then a Crankshaft Variation relearn is necessary.

How can doing any of those things have such an effect to where starting is not possible??
How many times have you and I pulled/swapped engines and it started with no problems?

I've done several without a problem. However, the PCM was sent in to ZZP to be reprogramed for the turbo. And that could have changed the security settings causing a no start. It'* still something I need to deal with before moving on to other issues. There'* not many things that will cause a no injector pulse.

Haven't hooked it up yet. And it better work, because I've tuned this car several times already.

Slowly working threw things. That plug isn't needed. That'* for 97 to 01 supercharged engines. It'* for bypassing the fuel pump resister.

Got it to start. Unplugged the MAP. It would seem ZZP didn't set the tune up right and left it as a 2 bar MAP for a L67 instead of a switching to a 1 bar MAP for a L36. I also think I made a boo boo. Looks like I may have forgot to put the cam magnet on. Opps.

Ehhh, no worries boss. I think we have all "forgot" something.

Oh waita minute. The CAM magnet! Remember that scene from "A Christmas Story" when Ralphy spills the hub cap of lugnuts? That'* my only response.

First time it fired up.


Just wish I hadn't forgotten the magnet. I would have been a few wires away from finishing. Oh well, no use in getting upset.

And here is the offending picture I should have looked at closer.
