1984 Pontiac Fiero - Answered Questions & Fixed issues

get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that sells very cheap but very very good manuals online Try this website here, reliable-store com also try manualslife both are good for this all the best

did you check the ground on the body also

About 8 ft-lbs or 84 inch-lbs. Max

If someone has not wired it to operate all of the time, I would say either a shorted out wire or a bad switch.

Check cooling fan temp sensor and relay

What fan? Coolant or heater? The rad fan can stay on with the key off for a predetermined time depending on engine temperature if the computer requires it to do so

What have you done to correct the problem?
have you check for voltage at the injector?
Do you have fuel psi at the rail before and after the fusl regulator?

ok you may be losing fuel pressure get it check but you may need a fuel regulator or a coolant temp sensor

is it getting fuel? (gas) is choke working..84 should have a mechanical choke..did you maybe get the wieres crossed.. check timing..

Running lights, marker lights, and dash lights all come from the park light switch of the head light switch. So, possibly you need a new headlight switch. Or, if you have a voltmeter, you can do some testing of circuits to see where power is and where lost. Also check the fuse for tail lights and horn.

remove the small wire from the solenoid and try it again if it cranks then you have a defective starter

it could be a bad throtle positoning sensor

The engine must be completely disassembled if the pistons were seized - all the piston rings must be replaced, the bearing shims will also have to go, the cylinder walls will have to be inspected for scratches.
Yes, putting oil in the cylinder will help, but it will not get it unstuck.

not the right gauge...to many volts

Sounds like the engine is siezed or is suffering from a liquid lock. Liquid lock occurs when one or more of the cylinders becomes filled with fluid. Air / fuel mixture can compress but liquid can not. Check the oil and coolant. If there is any water in the oil or oil in the water, then you most likely have a head problem. Could be simple as bad head gasket or could be cracked head. The only way to truly find out is disassemble the engine.

often circuits are run in series through the wiring harness, so a loop is created in the connections to continue to other things, In My Malibu I had to keep my original radio in the trunk wired up due to the computer and all the other stuff the radio had when replacing my factory radio with a new one

I'm slightly confused with your closed loop issue. Once an engine gets to normal operating temp and the O2 sensors reach their operating temp, the system will go into closed loop and stay there until one or both parameters that were previously mentioned fall below there specific value.
Are we speaking of fuel trim? If so, what is the constant fuel pressure reading while the vehicle is at a stand still and fuel system is primed, and what is the fuel pressure while idling and also while under load. Lean mixture could be related to fuel pressure.

I assume you replaced the temperature sending unit when you installed the aftermarket gauge? You need to put the proper sending unit back in for the OEM gauge to work.

You can find a sending unit here (and a gauge if needed):

Hope this helps

Hopefully you got home safe and w/o a ticket.

Parts for these are hard to find, here is a handy site that will have a proper replacmeent headlight switch.

If you open the hood, behind the headlight assembly you will see the motor that lifts the headlight, there is a knob that you can rotate to manually to crank up the headlight until you repair it.

Before you put it up manually, turn on the headlights with the hood open and listen to see of the motor is making noise, if it is you can try a repair kit, otherwise get a replacement from the auto part store or junk yard.

Here is a handy place for Fiero parts including the headlight repair kit I mentioned:
