No. The fuel pump relay is either working or its not. A relay works like a surge protector. A fuel pump produces surges of electricity as it pumps; a relay (large fuse) can only handle so many surges for so long, and thus usually at the half or three quarter mark of the life of the engine, these will "go out".

If replacing this does not solve your issue, consider having a diagnostics test performed (if you can get it to a parts dealer). If not, you'll just have to replace parts that are cheap. Here's a way you'll tell if a relay is bad:

Get a fuse tester and pull the fuel pump relay. There will (should be) four metal prongs on the bottom. You can't tell witch two are the live and feed so take two at a time and touch them to the two prongs on the tester until the light on the tester comes on - if the light does not come on when any two prongs on the relay are touched together with the tester, the relay is spent.

Before anything, however, locate the pressure valve on your fuel rail. After letting the car sit for some time after being started or driven, unscrew the valve stem, and depress the needle inside - if fuel sprays, then you have pressure. This will tell you that the fuel pressure regulator is still good. If no, or very little fuel is dispursed, then replace the fuel pressure regulator first. Also, check your airfilter and make sure it is not plugged, or torn. If so, replace. If it is excessive with dirt and debris, replace.

Also, replace the fuel filter. If your air filter, fuel filter, pressure regulator, and pump relay are all in good repair, or replaced - and the car still does not start, try one or both of the following:

1. MAS - the mass airflow sensor - clean with MAS cleaner (auto parts dealer).

2. Coil Pack(s) - if equipped - can be tested (modular under these cannot, so look for melted, white, bubbly substance - if present replace - have packs tested and replace any that are bad, and only the ones that are bad unless you prefer to do all - these can be a bit spendy per pack (not sold as set if more than one for some cars);

3. test the alternator - if the car will start, (even if you have to jump start it) with engine running pull the battery terminals off (both) and if the car dies, alternator is bad - if it remains running, it's good.

Please let me know if you need further assistance; feel free to view my tips page for more information.

Need to know why a 97 mercury cougar won't start until cooling fan and fuel pump stop running


I would think it's a problem with (CCRM) constant control relay module . This module has relay's inside that control the fuel pump , cooling fans , A/C compressor clutch , PCM - engine computer power relay . And thier are electronics involved , solid state circuity . Google CCRM

2003 oldsmolibe alero only starts with starting fluid then runs fine


well, the only cause is no fuel. it could be a blown fuse and or relay to fuel pump. or a restricted fuel filter. or a bad fuel pump. heres how to hear if pump is running. place hand on bottom of fuel tank, have a person turn key to on. you may have to do this a few times,if working, you will feel a vibration in tank. for a fuel pump only runs for a few seconds to pressurize the line to engine. but it runs all the time the car is running. check for a bad fuse or relay first ! good-day !

2000 mercury grand marquis 4.6 Intermittent problem. 35,000. miles. Problem engine died several times wile driving. Also after car is parked from a drive will not start. Found that the fuel pump is not...


I'd have to test when problem is ongoing. When you first turn on key, no crank, you should hear the pump run for a few seconds then stop. For initial prime, the computer doesn't need rpm signal. Engine cranking, the computer needs to see rpm signal or it won't ground the fuel pump relay. W/o rpm signal, no spark at the plugs and no fuel injector pulse. I know your talking about fuel, but, when problem is ongoing, check spark and fuel injector pulse, engine cranking.
Intermittent problems are a pain, have to test when problem is ongoing.

Not getting power to fuel pump and relays/fuses are good. And fuel pump is new and reset for fuel is still in place


Have you cycled the key a few times to get to this point. The PCM will shut off the fuel pump after 3 ( 5 ? ) cycles of not being started.
Did you bench test the realy ? My 2001 had an issue with the fuel pump relay, and the visual inspection on the relay it looked fine, but the normally open contacts would not close. I used one of the trailer tow relays to swap and test, sure enough that was the issue.

03 cavalier starts then dies


Generally when this happens all the time the fuel pump relay has gone bad. Upon starting any GM car up the fuel pump operates off the third wire on the oil pressure switch. When the oil pressure reaches operating pressure which happens in a few seconds the computer shuts off the current from the oil pressure sending unit and opens the circiut flow to the fuel pump relay. The relay will run ythe fuel pump until you shut the engine off. Replace the fuel pump relay and you shall have a good running car again

even though parts are new they also come with defects so it sounds as if when you turn the key you hear it working and other times not at all hmmm connections are tight ? could be faulty fuel pump or relay .

Rolls over but won't start until fuel relay clicks 10 or so times


Check for good grounding at both the fender where the relay is mounted and at the dashboard support Relays turn into "buzzers" when not properly grounded (also check ground right at the relay)

Fuel pump relay working intermitently.


is the relay ok? i think what you are hearing could be 2 relays at the same time. i think the fuel relay works with another aluminium looking one. there's usually a few of them that are identical so you can swop to check.
