Check power to the fuel pump relay. You should have constant 12V on 2 places. And when the key is turned to crank, the PCM should ground the relay.

well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

Assuming it is a fuel problem I checked at the carb. to be sure no gas was being pumped through the filter located under the power steering pump then the fuse on my 87 s10 was the ECM fuse.then check for the relay to click and the had to replace the oil pressure sending unit and mine started right up..the oil pressure must be about 4 lbs for the Pump tp operate...I loosened the fuel line to ck. for fuel but thats living dangerously...a pressure guage would be on the safe side......

Check your Fuel Lines and your Fuel Pump. (I just fixed a problem with my 2001 Isuzu Rodeo Fuel Return Line).

Also remember that in Rodeos, as soon as you turn your car key to turn the ignition on (just to make the dashboard lights go on) a certain amount of gasoline gets pumped to your engine in preparation of you turning the key all the way to crank the ignition and start the car. In other words, even before you turn the key all the way to crank the ignition, the Fuel Pump will pump some gasoline through the Fuel Lines to your engine (it will pump the gasoline for about 4 seconds then stop). So when you go to start your Rodeo, remember to turn the key with one continuos motion so that you start the ignition cranking while the gasoline is being actively pumped.

In addition, you should never turn the ignition lights on without turning the key all the way to start the engine. Doing so could cause that bit of gasoline that was pumped to start the engine to just sit there and create problems.

Citroen will not start


Hi my other half run our citreon picasso out of fuel on the motorway last week, I got 2 x cans of fuel and put into car, but battery went flat due to hazzard lights being on. I have charged the battery and tried starting it but it just winds over and will not start. I have tried towing it also but still no joy. Can someone tell me if the fuel pump primes when you turn ignition on as I cannot hear it if it does. Where is fuel pump located. Many thanks in advance Gerry

Does tapping on the starter work to start the car?


If it turns over, its not your starter. Fuel system or ignition system must be at fault. Test to make sure you have enough fuel pressure. If pressure is ok, its your ignition system. Fuel system consistes of fuel filter, fuel pump relay, and fuel pump. As far as ignition, check coil, ignition module, cap, wires, sparkplugs, and rotory button if so equipped.

Why won't my car start? It was running last night.


Try start the car again when it is completely dry, if it starts the rain may be short circuiting something on the loom in the engine bay.

If it still wont start,

will it turn over? (car tries to start)
- If it wont turn over the battery would be dead

- If it turns over but wont burst into life then we can go from there ^_^

Do I need to change the fuel pump or the fuel filter?


Have the fuel pump tested for pressure leak-down problems after engine shutdown. Repair the fault codes you are getting.

Fuse and relay for the fuel pump


The fuel-pump relay unit is responsible for turning the fuel pump on when it detects the engine is running. When the ignition signal stops, the fuel-pump relay switches the pump off. Problems with the ignition and starting the vehicle often can be traced to the condition of the fuel-pump relay.

Description

  • The fuel-pump relay is a small unit, typically enclosed in a plastic case. The unit contains several sprockets on one side that are clipped onto the ignition system. The fuel-pump relay is engaged only during the start cycle. If it is faulty, it can take longer to start your vehicle.
  • Location
  • Most fuel-pump relay units are located under the dashboard near the steering column. In some cases, the unit is located in the area where the steering column is mounted or near the engine's firewall. The end of the fuel pump relay is typically located near the center of the floorboard, under the carpet in the front section of the passenger's or driver's side footwell.
  • Considerations
  • In addition to difficulty in starting the vehicle, symptoms of a poorly functioning fuel-pump relay include the following: the car dies then starts a few minutes later; the fuel pump makes a strange noise (humming or clicking loudly) for longer than five to 10 seconds after starting; or the engine won't start after you have engaged the fuel-pump switch.
  • Troubleshooting
  • When your car does not start properly, you can conduct a fuel-injection relay test. Two relays are located inside the fuel-injection system; one of them is responsible for turning the ignition on without turning over the engine, and the other is responsible for turning on when the engine turns.



    You can check to see if the first relay is working by touching it while turning the ignition on and off. You should feel a "click" every time you switch the ignition. If the fuel-pump relay is not working, you can "jump" the unit with a small lead jumper cable. You will need to access the fuse panel and insert the cable into the relay unit; the unit will run as long as the wire is inside the relay and can help start your car.

    Get a DTC scanner and see what it says...in the meantime, check that fuel pump relay and fuel pump. The humming sound is probably the heater blower motor or part of the HVAC system winding down after disconnecting from power.
