Question about 1994 Ford Ranger Supercab
Will run fine once started. put noid light on; has very fast, weak pulse. is this a bad power control mod?
It is the ignition module or a failed coil . It the spark is faster than cranking speed then it is most likely the module.

i just had thhis problem myself on my truck...it could be a few things... check the fuel filter of course, then if thats not it...on the left side of the engine on the injector fuel rail there is a fuel regulator with a vaccum line attached to it... remove that and plug the vaccum line and see if that helps, if it does you have poor fuel pressure and need to flush your injectors...or fuel pump and if that doesnt work try wiggling your distributor, it worked for me... good luck

It sounds like you aren't getting fuel out of the cold start injector... remove the injector when engine is cold and switch on ignition... you should get a fine spray pattern for a few seconds... if not then there is probably a problem with the cold start circuit (Temp sensor fault), or the injector is faulty. pull electrical connectors one at a time and look for corrosion... Hope this helps...;-)

You could have something like a bad fuel pump pressure /injectors spray is not correct due to fuel/ engine lacking compression .
And its all due to varnish in the fuel clogging up the fuel ways BUT some thing to do about it is ADD 1 ltr bottle of PETROL to 20 gallons of diesel and you might need to add a little more in winter
but put it in before you fill up and do it at home as its out side the law,
Let me know how you get on Ron
