1988 camaro iroc z 350 tune port injected. need to reset timing on the computer. jodie

To set the ignition timing you will need to disconnect the electronic timing control. It is usually a dark brown and black wire located on the passenger side foot well where the carpet meets the firewall. Once the wire is disconnected, loosen the distributor and set the timing with a timing light. If you have an automatic transmission, I think the timing is 6deg BTDC. Tighten the distributor down and connect the ETC wire.

I need a fire timing order for a chevy astro van v6

CYLINDER NUMBERS (front-to-rear) :
LEFT (driver side) 1-3-5
RIGHT (passenger side) 2-4-6

To set ignition timing, ensure that engine is at operating temperature, (190 degrees or above), bypass EST (electronic spark timing) by unplugging the single tan wire with a black stripe from the distributor. Ignition timing should be set at 0 degrees or TDC (top dead center). If not, loosen distributor hold down bolt and adjust, then retighten.

Were is the plug to disconnect the computer from changing the timing on a 94 chevy pickup with 350?

Disconnect SET TIMING connector: The location of the set timing connector is inside the cab where the heater box and the carpet meet on the passenger side floor. Pull carpet back to expose the single wire and connectors on the outside of the control module harness. The wire colors are tan with a black stripe. DO NOT disconnect 4 wire connector at distributor.

Where can i get the specs for ignition timing on a 1989 GMC K1500 Pickup

Note: The Timing Connector breaks out of the engine wiring harness conduit adjacent to the distributer. It is a single wire sealed connector that has a tan with black stripe lead.
Note: Timing specifications are listed on the Vehicle Emissions Control Information label under the hood. Always follow the Vehicle Emissions Control Information label procedures first before using the following procedure. PROCEDURE:
Set timing under the following conditions:
  • Normal operating temperature.
  • Air cleaner installed.
  • A/C "OFF".
  • Transmission in neutral.
  • Disconnect SET TIMING connector (tan/black wire) located in the harness close to the distributor. DO NOT disconnect the 4 wire connector at the distributor.
  • Connect timing light and adjust as necessary by loosening hold down bolt and rotating distributor.
Base Timing, with Manual and Automatic Transmissions: 00(TDC)
  • Tighten hold down and recheck the timing.
  • Stop the engine and connect SET TIMING connector.
  • Clear ECM trouble code by disconnecting ECM power source.

I have a c3500 chevy silverado, 7.4 litre engine and the specifications for tuning is not under the hood. I do not know what timing marks should be. Please help. The distributor was removed and repleced to...

Is this tbi? I'll have to look it up but it should be set at zero degrees with the timing connector unplugged, I think. The timing connector is under the plastic relay cover on the passenger side firewall. It is a single wire plug that the wire is tan with a black tracer. With this unplugged you set the timing mark to the large gap on the timing tab.

How do you set the timing on a 350 chevy engine in a 1995 G20 van?

If the distributor hasn't been taken out, the timing can be set manually but you have to disconnect the distributor wire behind the glove box inside the cab. Tan wire with white tracer it is taped up to the a multi wire harness but is the only one with a single plug. Disconect the plug and use your timing light on the timing mark to set timing per specs. Rotate the distributor as needed to advance or retartd as required for the correct setting. tighten the dizzy clamp and plug the tan wire back together. The computer will now be fooled asd to what the base timing is and advance from there.
Contrary to popular belief, 96' and up do not have this wire. Timing has to be done with a programmable scanner.
Hope this helps.
