SOURCE: wont start. fuel pump klicks once only. no spark from plug wire

First check the fuses from the battery. The distributor is used to induce the induction coil which in turn sends it to the plug. Hence the contact point of the arm(silver contact point) needs to be replaced.....sodeep

I have a 1987 ford ranger the engine turns over but it wont start

Spark at plugs? Fuel filter? Pressure on injector delivery line? Pressure relief valve? You may be able to measure fuel pressure at the pressure relief valve location. and return line. If you have spark, I'd say it's a fuel supply problem

Spark plug blew out now car wont start

sounds like the autoshutoff relay may be controls the ingition and the fuel pump too..if the pump works check for spark by inserting a screwdriver into a pulled off spark plug wire and look for a decent spark between the screwdriver shaft and any ground like the block..if no spark the relay may not be powering up the ignition system..

Foel problem

When you smelt fuel, It was flooded. Your best bet would be to replace the spark plugs. Gas will foul them out, just like oil.

I put new starter and new fuel pump and is only craking the motor but don't start got good spark on coiol and the spark plug and still noting hany one haw a solution for that i will apriciet.

If you have good spark both at the coil and the plug, then your problem must be fuel. on the fuel rail there is a valve (like on tire) with key on, depress. you should have fuel flow, if not, listen at the fuel filler hole with the top removed for the hum of the fuel pump. If you hear the pump, and have fuel at the fuel rail on the top of motor, you will need to get help. The next area would be the injectors and they are controlled by the computer. The dealer will have to reprogram the computer. Hard but true.

Where is the fuel pump on a 1973 winnebago dodge 318? It will turn over, but will not start. Do you think its the fuel pump or something else? It has not been started for several years. Thank you so much...

Try putting a little gas in the top of the carb. Then try to start, if it starts then it's a fuel problem, clogged filter, lines, carb or fuel pump. If it doen't start with the gas then check for spark, disconnect a spark plug wire put on a spare spark plug, ground plug threads to motor and have someone turn over motor. You should see a spark between plug and electrode. Also you could check compression of engine, rings could be siezed and no compression will mean no start. If low or no compression, pour wd-40 or other lubricant into spark plug holes and let sit for a couple of days. Hopefully that would unsieze rings.

Wont start

is the your car engine cranking when you try to start, first check spark plugs ignition coils, remove one ignition coil and spark plug fix the spark plug in to the ignition coil then connect ignition coil to wiring and keep spark plug body touching on ground of engine head mettle parts, ask some one to crank engine then you can see is the plug sparking or not, do the same way to all the coils and plug otherwise you have to buy a ignition spark tester, is the all the coils and spark plugs are OK then check the fuel pump, it's sitting in under rear seat, before that do one thing disconnect oxygen (O2) sensor wiring and crank engine, the thing is if your oxygen sensor completely dead fuel pump will stop working, if engine start after disconnect O2 sensor, replace new O2 sensor, otherwise need to check fuel pump relay fuse and fuel pump. is this information helped you? please vote me and give a comment.
