1984 Buick Regal - Answered Questions & Fixed issues

I have a 84 grand national hot air. Just need to know how to rub my vauccm line after the EGR delete? Thanks

get the tranny serviced new fluid and filter

Check the coil packs for voltage , the cam position sensor and the throttle position sensor. Put a code reader on it and crank it so any new codes will come up.

Hope it's the correct one for the engine displacement. The best way to do this job is to go to an auto parts store and get the chilton manual for your car. It will explain all you need to know.

Backfiring is caused by either the firing order being incorrect or the engine timing is incorrect. generally backfiring through the carburetor is caused by incorrect firing order. confirm the distributor is inserted properly and double check firing order beginning with cylinder number 1.

You have a vacuum leak. There is a rubber hose going from the transmission to the intake manifold. Check that first. The other thing you might try is to disconnect the battery cables wait 10-15 minutes and reconnect. This will reset the onboard computer that also controls automatic transmission.

The cap is cracked or the wire has a break in it mobte the wire to anothet plug and see if it does it there

1 - 3 - 7 - 2 - 6 - 5 - 4 - 8 It has the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils The engine cylinder locations are numbered : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of Ford F-150 ( V8 )

Check all your fuses, they can come loose and get corroded on these cars. Give all the fuses a good wiggle to get rid of any corosion- and be sure they aren't blown. If it's not that, check your wiring harnesses to be sure they're tight.

I don't want to insult you, but did you check the fuses? Check the bulbs? Check to see if they worked on "high beam"? (possibly the dimmer switch, if all the above questioned items were checked and found to be good) Best of luck with it !

Just under the dash on the driver's side. GM always put them there, I think. They usually stuck out just a little from the very lowest panel on the dash. Post back if you need the code retrieval process and/or code descriptions, and I can give you a link. Or, what the hey, here it is:

Check your vacuum hoses. Holley aftermarket may not have as many vacuum ports as OEM QuadraJets, and you may have a vacuum line that isn't plugged into anything...or you may have a vacuum leak around the carb base gasket. Also, does the Holley have an electric or manual choke? Is it connected?

Did you replace the O-ring on the cable where it enters the transmission?

Have you checked the injector circuits with a test light to see if you have voltage and a pulse ground from the computer ?Can you spray carb cleaner into the intake to make it try to start ?

Are you check fuel pump pressure?

Duplicate question.

I would check for voltage and ground at the door switch.

it should be in fuel line going to carburator unscrew the fuel line and look inside where line screws to carb

• Hi, I can help. Please see the diagrams I uploaded for your firing order. You did not list weather you have fuel injection, turbo or carburetor so I will list all 3 possibilities for you.

• This is the firing order for a carbureted.

• This firing order is for a fuel injected turbo engine.

• This firing order is for fuel injection with out turbo.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Hello ojuice44,

If the bulb are good the next place to look is to check the fuses, if your turn signals work the fuse will be good. The fuse for the back-up lights is the same one for the turn signal..

After that there are two areas to check.

First, check for power and ground at the bulb sockets if ground is good and no power go to next step. If no ground repair the ground circuit ( See diagram below).

Second,check for power to the gear selector switch. Check for power with the key on and engine off going into the switch on the dark blue wire (See diagram below) if no power repair that circuit. If there is power there, then with the key on and engine off put the gear selector in reverse and check for power at the light green wire if there is power there the switch is good if no power replace the switch. If you do have power at the light green wire coming out of the switch repair the light green circuit from there to the taillights.



I hope this helps.
