EEC3 Testing .... fix my 83 September 25, 2006, 12:16:40 AM How????The car will start if you unplug one of the fuel injectors and hold it to the floor, when it fires over you have to take it down to half throttle then about 30 seconds later it will idle poorly....If you try and plug the other injector back in during the first 30 seconds it will stall the car. After about 30 seconds you hear a click, the high idle soleniod opens and bumps the idle up and then you can plug the second injector in and it runs rather nice but really rich..When you turn the car off the injectors continue to click for like 2-3 seconds and completely fill the throttle bores. So there is a horrid mount of gas waiting for the next restart.The car bellows black smoke, and not just a bit! This thing makes your eyes burn as well as my buddy's neighbors!!! I've went through and unpluged various things to try and get it to run in say a limp home mode but no luck.. it looks to have a new Iat but as chuck has said it doesn't have a new coolant sensor, try that?It runs like the time I forgot to hook up the hose to my map in my 88. lopey and Rich! I've unpluged the map wires during operation but no difference, almost like it didn't know it was there??? Now the only weird thing that has happend. I was reaching for the EGR sensor wire when the car was running and must have hit something because it died. I've unplugged the EGR and it didnt' make a difference. Nothing I've done makes it run any better.So can this car pull codes??? Every place says no.... I'm hitting a junkyard tomorrow here in Dayton. Maybe, just maybe I'll find another 83 and pull the comp and Map out of it. A new map is 216 bucks.. thats over half the cost of the car!!!!!!! Quote Selected

EEC3 Testing .... fix my 83 Reply #2 – September 25, 2006, 09:47:08 AM I am going to go out on a limb here. I've never owned an '83, never worked on one, never really tried to diagnose one. But I did get some information from owners of '83's a few years ago, and one thing stuck in my head. There is a crankshaft position sensor in the timing cover, about the size of a lipstick tube. IIRC it's still available from Ford (if not there just was one on eBay). When it goes, funky problems occur. I don't know if that would account for pooling fuel but I do know that changing it has solved problems for quite a few '83 owners. Just passing along what I was told, for all it's worth...

EEC3 Testing .... fix my 83 Reply #3 – September 25, 2006, 10:29:57 AM Thanks MasterBlaster!!! problems is I dont have a vacuum pump with me here.... Shouldn't I be able to just leave it hooked up?Now I'm trying to track down some info on testing the tps. when I read the ohms across two of the pins it gives a reading but it stays solid on the other two. (well there are only three total.) Quote Selected
EEC3 Testing .... fix my 83 Reply #4 – September 25, 2006, 10:40:31 AM To test the TPS is similar to an EEC4 system except the VREF of 9V IIRC. Green wire is what you probe and the other to ground. Just do a test sweep of the TPS signal voltage in an buttstuffog VOM.You will need the vac pump to run any kind of codes on the EEC3. What do you mean "should I just be able to leave it hooked up"? It almost sounds like the ECT sensor to me, but it's odd that the injectors continue to pulse after the car is shut off. Mine never did that. You're just guessing without codes, as primitive as they may be on the EEC3. Quote Selected

EEC3 Testing .... fix my 83 Reply #6 – September 25, 2006, 02:08:07 PM I have that book...bought it when I started to try and work on the 83. Good info. Quote Selected
EEC3 Testing .... fix my 83 Reply #7 – September 25, 2006, 02:21:37 PM Well I tested the TPS and it was fine. Now I guess I'll have to rent a vacuum pump from autohole and try it out. Quote Selected
EEC3 Testing .... fix my 83 Reply #8 – September 25, 2006, 02:32:06 PM Hell you could probably buy a vac pump for what the rental fee would cost you. They're not that expensive. Quote Selected
EEC3 Testing .... fix my 83 Reply #9 – September 25, 2006, 02:32:23 PM Oh and chuck I misread the directions stating to pull vacuum on the vent side of the sensor.Autohole has the free rental tool thing. I have a vacuum pump but its 2 hrs away at my house. Quote Selected
