    No it has power and no sulphur smell.

    Ok...where would this ign module be located?

  • mshell1271 May 30, 2009

    When the truck doesn't want to start it sounds like when you have a lawn mower that has run out of gas...makes that same noise. Wants to turn over but just not kick in. But after the truck has set for awhile it starts up like normal and runs just like normal.

    I did the cycling of the key and it started right up. But it has done that before after it sits awhile.

    When it runs, are you getting a sour sulphur smell from the exhaust or very little power?

There are a few things that would cause that wo all i can tell u from what u said is that u need to check for fuel pressure w/ a gauge then look up the specs online. if u lose pressure after start up the fuel pump is bad. but if it stays good as the truck dies then u do have other issues that someone would have to look it over. u could have a ignition module heating up and opening the circuit or an electronic coolant temperature sensor reading -40 or 300 starving or flooding the engine with fuel pull out a spark plug and ground the threads onto something. and check for spark as it dies. if it stops sparking then u need to look into the ignition system. if it does not then you are looking at a fuel problem or a cam positing sensor. which could shut off fuel injector pulse and ignition fire. like i said alot of componets could cause irratic behavior like this ull just have to start off with the basics fuel and fire before you can jump to any conclusions. oh and fuel filters would cause the engine to run bad but not kill it all at once and keep it from starting. one way to rule that out is to turn the key one for 2 secs then off for 6 secs and repeat a few times this turns on the fuel pump for priming iu the system. if it still does not fire up then somethin else is going on other than the fuel filter.

    yeah cycle the key to ensure the fuel pump is coming on and try to crank the engine. fuel pumps can heat up and go out. definitely since theres pressure on it. a drop of 30 lbs will kill an engine because it needs pressure to push threw the injectors. when it dies immediately go and beat on the fuel tank to try and free up the pump then cycle the key on and off and try to start it.

  • chris kelton May 30, 2009

    no no keep trying i know that it starts after a while. a fuel pump can cool down and start working again. if it starts then stalls and does not start up again, something is heating up and causin that problem. and since it sounds like it runs out of gas then we need to look at the fuel pump. ive seen this before on a ford focus with a brand new fuel pump it would start then stall out, then it would not start again for a while. then when i banged on the tank i could get it running and sit there and watch that fuel pressure steadily drop till the engine died. the fuel pump that was put in turned out to be the wrong pump. 2 diff pumps in the same year on the same vehicle was the cause of the mix up. anyway make sure u can hear the pump. after it stalls cycle the key and listen for the pump it will make a whining sound. pull the gas cap off if you need to

1988 ford ranger ( 4 cyl ) Fuel pump kicks on, motor starts and runs approx. 5 to10 min. and dies. Turn key back on and can't here fuel pump.

It sounds like your fuel pump is overheating. Once it gets too hot the bearings swell and the pump locks up. When it cools, they contract and the pump works again. It is also possible the fuel pump relay is having a thermal failure. You can determine this by hooking a voltmeter into the fuel pump supply wire and keep it where you can see it while it is running. If the voltage goes down and then the truck stalls, it would be the relay, if the voltage goes down after the truck stalls, it would be the fuel pump. Since the pump is only running when the engine is running, once the engine dies it'll turn off the fuel pump so it is important to pay attention to what happens first.

Ford ranger fuel shutoff switch

i bet its the ecm relay if it starts cutting out then dies then it is the ecm relay i had one that did the same thing if its your fuel relay unplug it clean the terminals and plug it back in if it still does it buy a new one and replace if you bypass it you take a chance of burning the truck too the ground and if ya dont really care about that then find your positive wire in the plug with the key on and hook it too the one that runs your fuel pump so its hard wired

1987 Ford Ranger that sparks but wont' start

try to replace the coil and all the spark plugs also make sure that the plugs are gapped right. that info will be on the evaporation sticker onthe core support in the front of the truck under hood. I think it is 0.004 not 100% sure on that. I hope that helps

My truck 99 ford ranger died while driving down the road

fuel filter usually dont cause it to die and not start back, thay usually cause rough running. see if your fuel pump is running by getting in and roll up all windows so as quite as possible then cycle the key from off to run and lisen for the pump to run for 2 to 3 seconds should be a faint buzz sound if no sound is heard then replace the fuel pump relay, if no help probably going to need fuel pump

i was once pulling a trailer with a ranger when it suddenly lost power and the engine died. turns out the problem was with the fuel shut off inertia switch. the switch is supposed to activate in case of accident. on my model the inertia switch is located in the passenger side under the glove box. dont know where yours is located. once you find it, just push the button and see if it resets. good luck.

Sounds like your fuel pump is going out on you. Check your fuel pressure. You should have 40 psi when the key is in "on" position. You should have no less than 5 psi under that when it's running.
