How do i check the conuity on the fuel relay 97 cavalier


there is a fuel pump jumper pigtail with a green plastic cover that if you run a power wire to it and the pump keeps running then it could be a fuel pump relay as you have bypassed the relay by doing this. if it doesn`t run then the fuel pump is the problem and needs replacing.

2002 cavalier 2.4 will not start fuel pump runs has spark


FUEL PUMP ONLY HUM'S FOR 2 SECONDS WHEN YOU TURN KEY TO ON, NOT START, POSITION. YOU CANNOT HEAR PUMP RUN WHEN CAR IS RUNNING ! THIS 2 SEC., IS THE PUMP PRIMING ITSELF TO START ENGINE. YOU MIGHT BE HEARING EITHER THE POWER STEERING OR WHATEVER, NOT THE FUEL PUMP!!!!!! GIVEN THE YEAR OF THIS CAR, YOUR FUEL PUMP COULD BE BAD, CHECK FUSES, RELAY, GROUND WIRES, TO PUMP, ALSO CHANGE YOUR FUEL FILTER !!!!! AIR FILTER ALSO !!!!!!! SPARK PLUG WIRES SHOULD ALSO BE REPLACED !!!!

Jeep fires but wont start


What is the year and model ?
You can use a jumper wire to bypass the fuel pump relay to see if it is loosing power or a ground signal from the computer.
The engine has to produce oil pressure for the fuel pump to keep pumping after it starts.
Are you loosing fuel pressure or spark ?

Wont start


I understand you replaced the relay but not the pump, right ?
Has the fuel filter been replaced recently ? Are you sure there is gas in the tank ?
You should be able to jumper the pump relay and check fuel pressure.

What typically is needed to to be done if a 2001 supercrew has had air bags deployed and wont start after that. The switch in the right kicker panel for the fuel pump does not appear to have been tripped....


Good info on the PATS / theft light. Looks to be the PATS / HEC operation is functioning correctly

The Fuel inertia switch only cuts power to the fuel pump, so if tripped, the truck would have a crank no start issue. Do you have a crank no start, or no crank issue.

To reset, just press down on it. To check if the switch is tripped, check for power at the connector to the fuel inertia switch

Engine compartment fuse # 10 ( 20A ) to the fuel pump relay -> Dark Green w/ yellow stripe wire to the fuel inertia switch -> pink w/ black stripe wire to the fuel pump module.
Check the pink w/ black stripe wire to ground with a meter for power, with the key in the run position.

If you turn the key from off to run ( do not start ) you should hear the fuel pump cycle ( hum, then turn off ).

Could be an issue with the fuel pump relay ( my '01 had a crank no start at ~ 35K miles, bad fuel pump relay ). I proved this out ( after a stupid ID10T error in my diagnoses process ) by jumpering the normally open contacts in the fuel pump relay socket, and then installing the trailer tow reverse circuit relay into the fuel pump relay socket ( same full size Ford Relay ).

Jumpering the fuel pump relay in the relay socket ( remove relay and use jumper wire ), red line

If you have a no crank issue, could be the DTR ( Digital Transmission Range ) sensor on the driver's side of the trans is out of alignment.

Check the start motor relay ( on the firewall on the passenger side ) for power on the Tan w/ Red stripe wire when the key is in the start position ( this is from the ignition switch through the DTR when in park or neutral to the starter motor relay ).

You can test another route, turn the key to the run position, and apply power to the Tan w/ Red stripe wire on the starter motor relay in the engine compartment on the firewall. BE CAREFUL, the motor should turn over, keep clear of moving parts.

Post back a comment to this problem with the results of the testing.

Thanks

Chevy cavalier 1998 2.4 ltthe motor starts but sudenly stops after 10 or 20 seconds running i cheked the gas pump line and it works ok, spark plugs are ok fuses oare ok the swuitch ignition seems to be in...


the fuel pump is triggered by the engines oil pressure switch upon starting
when oil pressure reaches normal psi the relay takes over powering the fuel pump
you see know that your relay is not operating now for the pump

Tuned up a 1993 chevy cavalier has spark won't start


Spray aerosol carb cleaner into the throttle body while an assistant tries to start the engine. If it runs for a few seconds then quits, you are not getting fuel into the engine. Check the fuses. You might have blown the fuse for the fuel injectors (possible if you removed any of the injector harnesses) or the fuel pump relay.

check to see if you can hear the fuel pump running.just cycle the key to the on position but dont turn over the motor you should hear a humming sound come from the fuel tank.if no sound check your fuses if all ok could be a bad fuel pump
or check to see if you have spark if no spak then it could be the module inside your distributor cap.it also controls the fuel pump.
