First thought: Check the idle air control valve, or whatever its Ford equivalent is. Sometimes these start to stick and cause the rough early idle that smooths out later.

SOURCE: truck runs rough

Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.

SOURCE: cold start

try this procedure:
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake. One last note have u done a fuel pump pressure bleed down test? it should not loose more than 5 PSI in 24 hours.

SOURCE: 1996 Ford Ranger won't start

I had the same problem , and if you read your book, it could be the fuel pump shut off switch, mine was bad and went from on to off position, its usually under the passenger side of the dash, look underneath at the "top" of the carpet, and you'll see a little red switch, check to see if the thing is plugged in , if it is , check to see if the switch is all the way down. i had to get a new one , sombody must have kicked mine and made it broken, but i got a new one and it worked fine

1989 Ford Ranger 2.3l. Won't start. Does not have injector pulse. Has spark on all 4 passenger side wires. Has at least some fuel pressure. Timing and belt good. This was a progressive problem in that...


The fuel pressure has to to 35 to 45 psi. And no low fuel pressure will not cause no injector pulse.The veicle sounds more like a idle air control problem why? because as you stated it runs rough when it does start.Get it to start sysle the key you will hear the fuel pump go on cycle it three times then start it up. when the vehicle warms up take the idle air valve out and clean it with carburator cleaner or even brake cleaner you may even want to do the throttle body itself this should help with the hard start up and rough running

1988 Ford Taurus hard start problem


Change the coolant sensor located close to the thermostat housing. This is easy but do not over tighten it. You will have the same problem if you do. Tighten till it does not leak only.Good luck!

My tuck idles low and spits gas out the exhaust


Since you have replaced all those parts already, I would suggest checking out the egr valve. Also I was wondering how the coilpacks or distributor are acting? Is the truck firing on all cylinders? Very possible you have leaky injector also.
