97 mercury mountaineer. won't start


hi,

watch your oil pressure when cranking, you have to have some oil pressure to get the fuel system to start. you may have to find the hot wire at the relay and energize it to see if it is indeed the fuel pump going out. if its been sitting and its a 97 the fuel pump just might have went, you can also try hitting the gas tank from the outside in the middle to see if that works too. have a water hose or fire extinguisher around when your working on fuel system and leave one of your battery cable a little loose..

Hey guys, my caravan started this morning then shut off and won't start again. Heres what I did so far checked fuel pump fuse good, fuel pump relay good swapped with other. Removed neg battery cab


If you have voltage at the fuse and relay, and at the pump, but no fuel pressure, I would say the pump has died or the tank is empty.
Have you checked for voltage at the pump yet ?

I have 1986 Alfa Spider that won't start. Car has been sitting for a year. I replaced battery, fuel tank, fuel sender unit, both fuel pumps. I seems that the in tank pumps is not getting any po


Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

My 92 Accord LX stopped running, I replaced plugs, wires, distributor cap, fuel pump and car still won't start


You will need to check for spark disconnect a sparkplug wire at the distributor and leave a 1/4 air gap,crank the engine, do you see a spark,if you have spark then solve for no fuel this can stem from a needed fuel pump that has failed.

Will turn over but wont start cant hear the fuel pump


If it hasn't run in a couple years, I would use a "test light" and check for power at the plug-in for the fuel pump. If ther's no power I would run a wire from the battery straight to the fuel pump itself. If the pump doesn't turn on you will have to replace the pump. If this starts it. If this makes it work you could put a fuse in the wire and hook it under the hood to any wire that has power when you turn on the key.

If you are trying to get it running again after 2 years it might be a good idea to pick up a Haynes manual for the car. They're only about $20 and have a lot of useful help for the DIYer doing average repairs. Hope this helps.

Replacing fuel pump do i need to remove tank 1993


No, you don't have to drain the fuel tank. All you have to do is relieve the fuel pressure. If your car will start, remove the fuse or relay for the fuel pump and start the car. Let it idle until it stalls. Then turn off the key and remove the negative battery cable (to prevent sparks while you work).

I hope this helps.

1999 blazer wont start??


Your battery is either faulty or ther is a parasitic drain, have it checked out at parts house. With a good battery installed, spray some starter fluid into intake housing. If it starts, then dies, you have fuel pressure/delivery problems. Can you hear the fuel pump run when you turn on the key? Hope this helps.
