SOURCE: 1985 Volvo 240 no fuel no spark

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

SOURCE: get spark, but no power to new fuel pump 1999 ford Ranger

the inertia switch is in front of the passenger seat, bolted to the fire wall, hidden by the carpet on an 89 and behind the kick panel on the 99. 99 should have a picture that looks like a gas station pump with a line thru it. pull panel off, push big red button. on 89 its the little grey button on the top.

SOURCE: i was having problems with

I have worked on quite a few chevys and can tell you what I've found to work with this type of problem. When you replaced the starter, did you tug on the fusable links that connect to the solenoid to see if one of them was burned and loosing power? There are two or three short pieces of fusable link attached to wires that power the fuse block and other electrical circuits at the solenoid / battery cable connection that will stretch when you pull on them if they are bad. If they are, then you won't have power for the fuel pump, relays and other circuits to make the truck start.
If one is bad, cut the wire behind the link connection and put a **** splice and piece of wire on it with a ring terminal,and connect it to the solenoid. Turn on the ignition and listen for the fuel pump to buzz. The fuel pump is controled by the ECM and makes the pump turn on for 3 seconds to prime the system with fuel before starting the engine. One of the wires on the solenoid with a fusable link does this. If this works, your done.
If the truck won't crank when you try to start it, check the "S" terminal for power with a test light while someone turns the key. The "S" terminal on the solenoid comes from the ignition switch, to the neutral/backup / clutch switch to the starter. You'll have to check every point in between these for power to locate the problem. One bad connection or part will keep the starter from getting power to the "S" terminal. You can use a screw driver to test if the starter is working by touching the two terminals together.
While your under the truck, look at all the wires in the harness for any chafing or rubing, I once found a wire that rubbed through and was causing the problem.
Hope this helps, Craig

SOURCE: xterra car quit running. had no spark @

Yes, there is fuel pump relay, which is generally located on the passenger side kick panel. But in your case, the fuel pump relay on 2002 model Xterra is indeed located under the dash around the steering wheel, but no you don't need to remove the cover just lay in floor and you can see it, it will slide off a bracket and you can remove and replace it.
Good Luck!

Car won't start? First thing would be to check all your fuses. Most fuse boxes...


Car won't start?
First thing would be to check all your fuses. Most fuse boxes are located under the driver side dash panel. Some cars do have an extra set of fuses on passenger side kick panel (foot area on door side)

If all fuses are good, then next thing would be to test your relays with an ohmmeter.

If all your your relays and fuses are good, you will want to check for fuel and spark. A car needs air, fuel and spark to run.

To check for spark, you can purchase and use a spark tester.
If you cannot obtain a spark tester, then the next best thing would be an ohmmeter. You can test the power coming from your coil packs or distributor depending on what you have. On distributorless vehicles (one with coil packs) the coil pack are attached to an ignition module. This module is powered by the Crankshaft Position Sensor. This sensor can be tested with an ohmmeter. The Crankshaft Position Sensor is the first thing to be tested if you have no spark in any cylinder. If you have spark in some cylinders but not all, then check the coil pack (1 pack per 2 cylinders).

If you have a distributor, test the coil that provides the spark.

If you have plenty of good strong spark, then the next step would be to check for fuel.
Fuel system consists of Fuel Tank, Fuel Pump, Fuel pump Relay, Fuel Filter, Fuel Pressure Regulator and finally carberator or injectors.

Fuel injected systems have a fuel rail. On the fuel rail is a test port for fuel pressure. If you have a fuel pressure tester you can test how much fuel pressure you have. Or you can place a rag over the valve and press it in to see if there is pressure. If not pressure, check that pump is running. You should hear it run for a few seconds when key is first placed in the ON position. If pump is not running, check fuses and pump relay.
If pump is running but fuel pressure is low, check for leaks, plugged fuel filter, or leaky injector.

My car wont start,you turn the key , and sounds like it's going to start but it just wont' i already take to the mechanic he had the car for about 2 months i get the car back ; he said it was fix and now...


FIRST GET A SPARK TESTER TO SEE IF YOU ARE GETTING SPARK AT SPARK PLUGS.IF NOT CHECK IGNITION MODULE FUSE.IF FUSE GOOD HAVE CAR HOOK UP TO SCANNER LOOK FOR IGNITION MODULE FAULT CRANKSHAFT SENSOR FAULT AND PCM FAULT.IF ALL LOOK GOOD SO FAR.CHECK TO SEE IF FUEL PUMP WORKING.CHECK PUMP FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER STILL LOW REPLACE FUEL PUMP.IF FUEL PUMP NOT WORKING AT ALL CHECK FUEL PUMP FUSE AND RELAY.IF BOTH IS GOOD FUEL PUMP AT FAULT.BUT SCAN TO CHECK FOR PCM FAULT CODES IT CONTROL SPARK AND FUEL SYSTEM.MAKE SURE SPARK PLUGS AND WIRES IS GOOD. ALSO CHECK FUEL INJECTORS FUSE ALSO.

3 THINGS WILL CAUSE CAR TO SHUT OFF ON HIGH WAY.LIKE ALTERNATOR - FUEL PUMP - SPARK IGNITION COIL OR MODULE.FIRST OF ALL IF YOU HAVE DASH LIGHTS AND HEAD LIGHTS.ALTERNATOR OKAY YOU GETTING POWER.LISTEN FOR FUEL PUMP TURN ON IGNITION SWITCH ENGINE OFF LISTEN TO HEAR FUEL PUMP RUNNING IN GAS TANK.IF YOU HEAR NO PUMP RUNNING IN GAS TANK.CHECK FUEL PUMP FUSE AND RELAY.BOTH CHECKED OUT GOOD MORE LIKELY FUEL PUMP AT FAULT.IF FUEL PUMP RUNNING CHECK FOR SPARK AT PLUGS.IF NO SPARK.CHECK IGNITION FUSE.IF FUSE GOOD YOU COULD HAVE PROBLEMS IN THE PCM SINCE IT CONTROLS SPARK IGNITION SYSTEM.

My 1991 honda civic runs fine yesturday and today it wont start please help


the car wont start? do you mean the engine wont turn over or it wont fire or run? if the car does not run but it turn over, check the basic..see if you have sparks and fuel, then check all your fuse pertaining to engine and ignition. the car need to have both thing in order for the engine to run. If you getting both sparks and fuel you engine may have jump time especially with older car with high miles, it the sign timing belt getting worn, you don't want it to break. if you don't get fire from spark plug then you may have a bad coil,distubutor,rotor or timing sensor. if you get no fuel, fuse blown, bad fuel pump relay or fuel pump it self. hope that help some ..good luck

Just stopped running at 65 mph, has good battery , all lights work ,turns over feels like no spark or fuel , is it a timming belt or chain ? and ideas where to start?


ok,i need more info,lights work a]could you test your battery to see if it good probably 11.7 to 12.1 volts,you will need a voltmeter.b]when you crank it, you need to verify for sure if it has spark,feel like no spark or feeling no gas does not help,pull out a spark plug boot from the spark plug,insert a small screwdriver and keep the screwdriver metal 1/4 away from any good ground and then crank it,if you have spark you need to check for fuel,rent a fuel pressure gauge at autoparts store and check for fuel pressure and give us those numbers,if you do not have spark and fuel probably you need to change the ignition module,or ignition switch,but if you have spark andyou have fuel you need to check with a scanner the status of the crankshaft sensor to see if it recieving volts .let me know when you have some numbers,if for some reason you can not perform these test leave alone and pay a mechanic ,it does not worth it that you get hurt trying fixing something dangerous.keep me post it.
