SOURCE: Electronic Control Module Installation 1994 G20 Chevy Van

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.

1994 G20 conversion van. 6 cylinder. Engine running in park. When I apply brake. Engine quits then van will not restart.


Check vacuum lines.
There is a large one on the power brake booster that goes to the back on the fuel system. Make sure you have vacuum before you try anything else.
A vacuum leak will cause you to stall out.

My 1992 chevy g20 van surges and i'm not sure exactly why. I changed the pcv valve, fuel filter, spark plugs, and air filter. What are some possibilities


My first thought would be a vacuum leak in one of the hoses. Rubber hoses get brittle with age and even a small crack in a hose may cause surging. Happened to me in a Lumina.

How do u replace a heater core in a 1994 chevy g20 conversion van


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.
