I have a pontiac parisienne 1984 that dont start. Ive tried sparks and wires, fuel pump and filter. Could it be the starter?

Excessive cranking will put too much fuel into the engine. Have you tried holding the gas to floor and see if it starts. That will help clear out excess fuel from continued cranking.
Check for spark at a sparkplug wire. This will tell you if ignition system is working. You need to see a blue snapping spark to know ignition is good. If you are not sure how to check for spark, have someone help you. Easy to get a shock when checking for spark. You need the metal end of the plug wire just 1/8 inch to 1/4 inch away from a metal bracket or bolt on the engine. Hold it steady while someone cranks the engine over-watch for a strong blue spark to jump from metal end of wire to the engine. If no spark, your ignition system needs checked. If spark is good, have the fuel pressure checked-maybe it is getting too much gas.

Sounds like your ignition switch could be bad. Also check the alternator plug and starter wires. With time can become loose.

I had the same problem in my 83. I went threw 3 fuel pumps before I dropped the tank and removed the clogged nylon strainer. It was easier then it sounds. Then I put a generic in line fuel filter to protect the fuel pump. Good luck and hope it helps.

Acording with 1984 PONTIAC PARISIENNE 5.0L 4BL OHV 8CYL - REPAIR GUIDE, This system incorporates a bleed in the pressure regulator which automatically relieves pressure any time the engine is turned off, but a small amount of fuel may be released when the fuel line is disconnected.

To reduce the chance of personal injury, cover the fuel line with a shop cloth to collect the fuel, and then place the cloth in an approved container.

The Fuel Filter is located under hood, center, upper engine area, mounted in fuel inlet line connected to carburetor.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice weekend.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Could be a few things from the actual light switch to the wiring to the lights themselves or as simple as your fuse for them. You have to check em all to see which one has failed. Start with the fuse then headlights as those 2 are the easiest.

firtt make sure the pump is not clogged up , then if u remove the relay and put a piece of wire across 2 off the terminals to make it run constant to see if pump ump is working , or u could wire the pump up to test
