I posted this on rangerstation site but havent got a answer yet. I thought maybe someone here could help. The first paragrapgh of listed below as pertains to this site also



I just joined here and have been reading and searching on this problem and the last thing I found was a post that was old. So I am sorry if these question makes people angry

I have a 87 ranger XLT two wheel drive with five speed It has the 2.9 Liter in it 148,000 miles just had fresh plugs, wires, Rotor, cap, Module on side of distributor and Pick up module in dist put in (sorry it has the E?? IV ignition on it). I have reset timeing to 12 degrees before TDC and it runs fine but after it is sarted and drove it is hard to get started again. It turns over fine but it acts like its not firing (which it is I have visually checked by pulling plugs). But after cranking on starter three or four times for 10 to 20 seconds and hold foot feet to floor it will start but it acts like it is flooded out you know coughing and blows out a little black smoke then it will run fine. Pulled plugs after this they wern't fouling. I haven't put pressure gage on rail port but have check to see that ther is gas present in injector rail it squirts out after shutting engine of and letting it sit for fifteen or twenty minutes I thought it might have a weak fuel pump that was allowing gas to flow back to tank also has plenty of gas squirting out when running. If this thing had a choke I would almost say that it was going full choke when it only need a slight choke to start. Could this be a sensor problem with a air gas mixture thing or something else? I have read through the chiltons book on this but they really don't have trouble shooting in them and the only theing that come close to this problem in thier book answer is check choke plate but they don't talk about a chock plate. Please help athis problem is driving me nuts and noone around me has got any answers.

Thanks in advance for replies,

Charles

It might be your A/F sensor or injectors, the computer is probably not reading the injectors. I've been tell a lot of users on there website to hook up a code reader to their vehicle to the problems but there was this one guy thst I told him to hook up a reader to still nothing showed up then I ask him to check the feul pump and that was the problem. So knowing faulties with Fords and feul that's probably what it is.

bought a code reader today and in the test KOER got code 21,33,77
figure I will run down to parts store and get the coolant sensor and try that

Well at least it's no the feul system, thats always goods. :-)
