Mike-

Not sure if I should help... (remember that PCM I set up for you , and then stiffed me?)

Do you have a P1629 ? Check on HP. If not then you don't have a Passlock issue.

You should be able to get the injectors to fire at initial crank for a few seconds - if there have not been any start attempts for at least 10 minutes. If you never get the injectors to fire, then it is not a Passlock issue.

I did not see that you have verified spark. Passlock will not disable spark.

Do you register a cranking RPM on HP or a Tech II? Should be 180 - 200 (with a good battery/ starter). On the Tech II you should see the CKP Activity Counter smoothly increment (rollover at 255 cnts).

I did not see a HP log. That may help.

Mike I'm sorry if you felt like I stiffed you. I did hear back, so I found another PCM. I'm sorry that you put time into setting up the PCM for me....

I do not have any codes at all. Not even one. Verrified wtb hptuners and a scan tool. I have spark but the injectors are not firing at all. I have fuel at the rail. I'll Check Sunday to see if hptuners can see Cranking rpm. I can email u the hptuners log of me trying to start the car if you like.

I'm beating on the cluster, but I would check the plug on the cluster as well.

HPTuners can not see any cranking RPM......I retraced the CPS wires to and from the PCM, and well yeah......they look and measure fine with an ohm meter. FML.

@!#$ it... dump some gas down the throttle body and crank the SOB.

i know thats ghetto but at least you'll know if it is a fuel or a spark issue.

(hopefully it doesnt backfire and blow the welds on the intake )

Please send or post a HP log.

If you have good CONSISTENT spark then the ECM is recognizing the crank sensor. The ICM filters the crank sensor VR signal and converts it to a square wave for the ECM. The ECM decodes the 7X signal to issue spark to the correct coil pair. Then it follows that HP should log RPM during crank. It should start and run via Z YAAAA's suggestion.

If the Z YAAAA injection works then lets figure out the fuel deleivery side.

Do you have 12V on the grey wire to the injectors (CAVITY A) at all times, even during crank?

You noted the check of the CPS (cam position?) - don't worry, this will not cause a no start.

(betting it's not the cluster if it does not set a P1629)

I was checking the crank position sensor wiring....again.

I'll check the grey wire sometime later in the week when I get time to work on the cav again.

Inside HPTuners what should the P1629 be set to?

This is what HPTUners is saying
PCM 1630-Theft Deterrent Learn Mode Active (SES) (Pending)History current (immature)

I'm also getting Relink Error.....
This vehicle does not support VATS relink.


Also borrowed some noid lights again....and injectors have no pulses going to them at all.

Your profile indicates a 1999 J body.

My code list shows only a P1629 for that model year:
DTC P1629 Theft Deterrent Fuel Enable Signal Not Received
This is a PassLock I system with UART communication to the cluster.


You are setting a DTC P1630 "Theft Deterrent Learn Mode Active".
I only see that in the 2000 and newer PCMs (Passlock II with a BCM). Along with:
DTC P1631 Theft Deterrent Fuel Enable Signal Not Correct
DTC P1632 Theft Deterrent Fuel Disable Signal Received


Are you trying to run a 2000 or newer ECM in a 1999 J? What PN is that PCM?

My old PCM P/N is the same as the 2000 plus P/N. If I remember correctly.....A long time ago I flashed a 2000 reflash onto my stock computer. Car ran, but I lost a few gauges. I then re-flashed back to stock. Car ran fine for years afterwords. I'll try to have the brother text me the part number off the PCM. I probably will not be able to get to the car till the weekend again.


Would it help if I sent you my HPTuner file for the stock flash?

So if I use my new PCM or my old stock PCM that came with my car.....I get this DTC P1630.....

I do not have a BCM in my car like the 00' plus J-bodies, and I have a 99 Cluster.

m dailey do you still have that PCM I was going to buy? I wonder if somehow Lordstown or a dealer installed a 00 plus computer in my car. According to the wiring schematics I have, my cav is wired like a 99 "should be."....and not like a 2000 car.

WHAT THE @!#$

I'll take pictures of my stock PCM tomorrow or Sunday......

I do still have the 97 - 99 ECM (GM service #16228016). I might still have it set up w/ your VIN.

I haven't responded since I don't know if you can successfully run a 2000 ECM with a 99 cluster - I was hoping some else had tried. The only way I have done this is with a BCM and cluster swap.

97 - 99 ECM pin out:
C1-14 TAN 800 Serial Data (UART) DLC Term 9
C1-58 -- -- Not Used
C1-59 PPL 1807 Serial Data (Class II) DLC Term 2

As far as editing the diagnostics for Passlock codes, I have not needed to as long as you disable "VATS" in the calibration. Not sure if that's always the case with all platforms, though.

Mike
Re: Starting or lack of.....
Thursday, January 28, 2010 8:39 AM
I previously disabled the VATS with Hptuners....per.....
1. Set the VATS value to "PWM"
2. Set DTC P1626 to "3 - No Error Reported"
3. Set DTC P1629 to "3 - No Error Reported"


I did this to try and see if the car would start. The car would still act the same, but not set the P1630 DTC. If I set P1626 and P1629 back to the original settings, I again get the DTCP1630 code.

I'm confused.

To disable VATS you go to the Sytem tab, then General, it should have Security VATS Disable or Enable, and VATS FuelCut Disabled or Enabled.

This is how you should disbale VATS. Is this what you are doing? I looked at your stock file you sent me and it shows disable. Maybe Enable it and see what happens.

Taking a picture of the ECU is not going to help much. They are the same on the outside but different on the inside. People have run a 00+ program, or ECU on a 99 but you lose gauge functions.

I also looked at another 99 Z24 auto stock tune I have. It also had VATS Disabled, and this was not modified but anyone.

Have you done this to the "T"??

PASSLOCK Changing - Components Description
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.

All codes in the theft deterrent module must be cleared for a relearn.


Engineers design the Passlock™ system in order to prevent theft even if the various theft deterrent parts change. The Tamper mode will engage if any of the following components change:

• The Passlock™ lock cylinder

• The instrument cluster

• The powertrain control module (PCM)

If you replace any of the above components, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator stops flashing. If you turn the ignition switch before the indicator stops flashing, repeat the long tamper cycle from the beginning.

Mike don't you have the racetronix pump in? Have you tried putting a stock pump back in to see what happens? I mean yea its a long shot, and I still wonder why Racetronix say the Racetronix pump is for plastic tanks only.
