I just had the same problem. If it is a regular van try under the driver seat in a plastic box. If it is a conversion van try in a pannel just behind driver seat on side of van wall behind a pannel that looks like a vent.

SOURCE: barely runs , timing retarded , only runs when est bypassed

You have set the timing to zero right? Then after you hook the bypass back up what does the timing go to?

CODE 42 Trouble Code 42 indicates that there may be a malfunction in the Electronic Spark Timing (EST) system.
During cranking, the timing is controlled by the ignition module while the ECM monitors the engine speed. When the engine speed exceeds 400 RPM, the ECM sends a BYPASS signal to the ignition module which switches the timing to ECM control. The ECM calculates what the timing should be then "tells" the ignition module via the EST circuit.
An open or ground in the EST circuit will stall the engine and set a Code 42. The engine can be re-started but it will run on ignition module timing.
The conditions for setting this code are:

  • System in BYPASS mode but the ignition module is still controlling timing
    - or -
  • Engine speed > 600 RPM with no EST pulses (ECM controlled timing) going to the ignition module for 200 msec.


Typical causes for this code include:
1) BYPASS line is open or grounded
2) EST line is open or grounded
3) PROM or CALPACK not seated properly in the ECM
4) Poor connections between ignition module and ECM
5) Poor routing of EST harness and/or poor quality ignition wires (EMI induced electrical noise)
6) Faulty or incorrect ignition module
7) Faulty ECM

I need help locating a module ignition modulator in a 2003 Chevy Tahoe


Who told you that one ? Module ignition modulator 2003 Chevy Tahoe ! No such thing! Your best bet would be to take your vehicle to a qualified repair shop .
The electronic ignition (EI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system consists of a separate ignition coil connected to each spark plug by a short secondary wire. The driver modules within each coil assembly are commanded ON/OFF by the powertrain control module (PCM). The PCM primarily uses engine speed and position information from the crankshaft and camshaft position (CMP) sensors to control the sequence, dwell, and timing of the spark.

Pontiac bonneville 1992 wont start


If it was running good before, you probably lost spark or gas to the engine. If you spray a little starting fluid into the throttle intake and the engine starts briefly from that, then you know it was a fueling problem. Check the fuel pump and fuel filter, or do a fuel pressure test. If no fuel pressure at the engine's fuel rail, you would need to check the fuel pump circuit before condemning the fuel pump.

If spraying starting fluid doesn't do anything, then it may be a spark (ignition) problem. Check for spark from a spark plug wire with the engine cranking. If no spark, suspect a bad Ignition Control Module, or the crank or cam position sensors, possibly a bad ignition coil, or as a last resort a bad PCM, but such is rarely the problem.

It's kind of a long shot, but there may be a trouble code that indicates the problem. Get any possible trouble codes to flash out from the check engine light, by using a paper clip at the diagnostic link connector.

"Code 42" would indicate that the Electronic Spark Timing (EST) signal did not change when the ECM applied bypass voltage to the ignition module. Check for faulty connections, or a faulty ignition module.

it is a 42, 96 on up use a OBD-II system to read codes. older than 96 use an OBD-I system to read codes. 42 means - electronic spark timing or bypass fault. this means that BYPASS line is open or grounded,
2) EST line is open or grounded

How to install a 1992 chevy pickup camshaft sensor 1992 chevy pickup 1500 z71 and where is it located? i have no spark coming from my coil so this is my next task? any other answers?


There isn't a camshaft sensor. The distributor has a control module and a pick up coil inside of it, 1 or both could be bad, it's usually best to replace both. Some parts stores can test them. The is also an Electronic Spark Control Module. I would check the pick up coil and control module.

Hey, your right about code 42 being the Electronic Spark Timing. The Electric Spark Timing Bypass curcuit or EST circuit is either grounded or open. A malfunctioning HEI module can cause this code so I suggest maybe trying to replace the HEI module. Good luck!
