My 1992 gmc only turns over but wont start. it ran no problem before i had to remove computer to access the heater motor. reconnected computer now truck only turns over but doesnt start

Recheck the computer plugs to ensure they are fully engaged. Hopefully, you unplugged/plugged the computer with the battery disconnected since these devices are not intended to be plugged in hot.

My 94 cadi fleetwood broughm has a fuel problem. The #6 spark plug keeps flooding with fuel. I replaced the injector, the regulator, the filter what else could it be?

Possibly the spark plug is not firing.. Change the plug. Check to see if it is firing? If its not then find out why? Coil, Plug wire, Plug wire connector, Possibly something as sinister as the computer, but, i doubt that it is the computer.

Computer reads misfire cylinder 2 and 6

Like Ronald Wilson said it could be something linked to the ignition ( ignition coil, spark plugs or spark plug leads ).
No injectors or oxygen sensor.

Car running rough after spark plugs. Changed on a 2001 Ford Focus

There could be too many reasons. Were the plugs gapped correctly? Are you sure that the wires are correct in order? If so, the next thing you should try is to reset the computer. Sometimes it is possible for the computer to read the old spark plug values even if you replace with new ones. Reset the computer by disconnecting the battery for 10-15 minutes. The reset may cause the computer to take time gathering new spark plug values until few duty cycles. I hope this information helps you!

Where under the hood is the computer plug


Not sure which computer plug you are referring to, as your vehicle does not have any computer connections under the hood.

All computers are mounted in behind the front console (in behind the ashtray area), and some computers up inside the sides of the dashboard.

If you are simply referring to your vehicle's OBDII plug, then this connection is UNDER the dash, above the driver's knee.

I unplug my battery , and when I plug again my radio doesnt work , the radio ask me for a code what I do?

Each time you disconnect the battery, the computer loses all codes for security system, radio, etc. If you know the code for radio, enter it into radio using the number buttons. To prevent this again in the future, you should purchase a power cord for the computer. It has the lighter plug on one end and a plug you connect to the car's computer. Plug the lighter plug into any 12 volt plug (not the lighter socket in your car) can purchase a portable jump starter with the 12 volt socket. The purpose of this is to keep the car's computer "powered" while you disconnect the battery.
