Wont start sometimes


NO. Fuel pump relay controls the fuel delivery. You should NOT be hearing ANY clicking sounds when starting. If you have a manual tranny, you have a starting system that includes: a starter relay, a clutch safety switch, ignition switch, starter, battery.



On my \'91 Integra, I by-passed the normal starting system by running 2 separate 12-guage wires to the dash (thru the firewall, mounted along the firewall over across to the starter and to the under-hood fuse panel). I connected 1 wire to the under hood fuse panel (for power), and the other wire directly to the starter relay. Then, at the dash I connected both wires to a high-quality "momentary-on/off" toggle switch - this is my starter switch. I turn the ignition key to when the dash lights come on, then flick the switch, and BINGO the car always starts right up.



BUT, this is somewhat unsafe because it doesn\'t use the clutch safety switch - which is nothing more than a spring-loaded switch on the arm of the clutch pedal connected to the ground. IF you are using the standard starting system, you MUST engage the clutch for the starting system to make contact with the ground in order to engage the starter. So, check this switch first for a good connection to ground. It usually fails first before anything else. If it checks out, THEN check the starter relay, located waaaaaaay up underneath the dash, right in the middle. To get at the starter relay, you\'ll have to remove the glove box, and plastic & metal kick panels on the passenger side. The relay is located way up underneath the dash, next to the Blower housing. You\'ll need a long socket extension to reach it. Someone at Acura/Honda decided this was the best place for it. Boy would I like to whack him with a 2x4.



See this diagram for reference - the starter relay is #15.

My mitsubishi eclipse 95 gs wont start and theres no light on my dash bored it will cranck but wont start at all i need help asap


Since the engine cranks, the battery, starter motor/starter motor solenoid are most likely
good, so suspect everything else on the list. When you narrow it down, re-post with a
more specific question about that particular component, since 100s of components must operate
nearly perfectly for a vehicle to actually start.

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Battery Cable Connector -- Broken/Corroded/Loose.
4 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset (aka Spark Plug Wires) -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injectors -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer (inside fuel tank) -- Clogged or Dirty Fuel Pump Strainer.

I have a 1992 geo tracker. when i turn the key nothing happens. i replaced the starter and cleaned all the wire to the battery. this worked for a while . then when i turn the key with the spade connector...


Check the ignition switch steering in column, it goes bad also over time, you cant fix or rebuilt it and its expensive unit, will have to buy a new unit or one from a junk yard, assuming the battery has a good charge and new starter. try to play with the ignition switch by turning the key back and forth many times and see if you get some kind of contact to the dash light or starter while everything is connected.

I have a 1988 Jaguar vdp, when i go to start the car the dash lights go out, and turns the starter. But no power goes to ignition. I have changed the ignition switch. Don't know what it could be?


If the engine turns over it is not likely an ignition switch. Can you hear the fuel pump kick on? Is there spark at the distributor cap? My thought leans towards either a bum fuel pump or ignition amplifier (ignition module). If you would like a manual to aid in testing, let me know.

I have a 2001 Olds Ayrora that won't start....dash lights come on, and when you turn the key it just goes duh duh duh ehhhhhhh.....any suggestions?


Does the fuel pump run when the ignition is turned on? If not, start tracing the wiring to the pump. There is a connector near the frame by the back right wheel that can cause problems.
If the fuel pump runs, does the starter engage?

My car wouldn't start once in a while, mechanic checked it and says diagnostic report shows nothing wrong with car but thinks it may be fuel pump.


Here are a few possibilities: 1) Fuel Pump and/or connections to it. 2) Ignition switch 3) Starter/solenoid 4) Security system - if equipped
If, when it won't start, you get ignition lights on the dash, then listen to hear if the fuel pump runs. It should run for a bit and then stop. If it doesn't run - then look in the area of the fuel pump and wiring. I had one where the fuel pump ground was loose and it would do this about once a week. If the pump runs, then look at the wiring and solenoid.
If you don't get any instrument lights with the ignition on, then you need to look at the ignition circuit. I had a case like this and it turned out to be a bad ignition switch - very intermittent.

Will not start when hot. starter makes no different types of noise.


hello. perhaps I can assist you.

Perform this test:

Fuel pump test:

1. Get yourself a helper.

2. remove the gas cap.

3. have one person listen in the gas tank at the gas cap opening.

4. have the other person turn the ignition switch to the ON position ONLY so as the dash lights come on. Do NOT attempt to start the engine.

5. As soon as the ignition key is turned to the ON position, The person at the gas tank should hear the fuel pump run for TWO SECONDS and then it should STOP.

6. Does it ?.


If you do NOT hear it run, in most cases the fault is the fuel pump relay or the fuel pump..


As soon as you turn ON the ignition switch to start the engine a 2 second ONLY battery voltage signal is sent from the computer to the fuel pump relay and from the relay back to the fuel pump in the fuel tank. This runs the fuel pump for ONLY 2 seconds of which pressurizes the fuel system in preparation to start the engine.

Once the engine starts, The computer BYPASSES the fuel pump relay and sends constant contionous battery voltage from the computer to the oil pressure switch of which is now CLOSED because the oil pressure is UP because the engine is running. Therefore the battery voltage flows thru the oil pressure switch back to the fuel pump to run the fuel pump constantly until you turn OFF the engine.
