94 Escort Wagon - Strange fuel cut off issue
Ok, so first let me say that I already read this entire post without finding any helpful solutions: http://www.automotiveforums.com/vbul...d.php?t=361126
Here is my car info: ------------------- 1994 Ford Escort LX (Wagon) 1.9L SEFI engine Just installed a new timing belt, water pump, thermotat and serpintine belt (the car was running great) Here is the exact sequence of events that caused the issue: ---------------------------------------------------------- I was working on the car I backed up on to wheel ramps so that I could check the exhaust I noticed that the car was idling high, so I removed and lubed the IAC with WD-40 I put the IAC back in place with grey RTV and tightened it down ( It's not leaking at all ) Here are the exact symptoms: ----------------------------- I turn on the ignition switch The fuel pump pumps and sounds normal The Fuel gauge shows about 3/4 tank (which is accurate... I recently filled the tank) The low fuel light comes on (which makes no sense to me) When I turn the ignition to the start position, the car cranks and sounds normal, but it doesn't even attempt to run. Also: when I crank the car the Low Fuel light goes off, but the Fuel Cutoff light comes on (only while cranking) I also notice a slight smell of gasoline, but I can't find any fuel leaking or dripping anywhere! What I've tried: ---------------- Looking for fuel leaks ( can't find any) Made sure the IAC is properly connected Verified and tested the Inertia switch in the right rear of the car ( it is working properly and has not been tripped). When I trip it, the fuel pump does not run. When I reset it the fuel pump works properly again. Disconnected the + battery cable for 5 minutes or more in an attempt to reset the ECU. It didn't help. Symptoms remain the same. +++++++++++++++++++++++ Any ideas? What more can I try to troubleshoot this? I wish that I had an FSM for this car! |

Re: 94 Escort Wagon - Strange fuel cut off issue
ok, here is some additional info that I found reading a Haynes manual:
"To clear the trouble codes on a 1.9L model, start the KOEO test. When the trouble codes begin to appear, remove the jumper wire from the STI terminal. DO NOT disconnect the battery to clear codes on a 1.9L model." I don't know what a KOEO test is, or how to perform it. Nor do I know what the STI terminal is, but atleast I go some info :-) |

Re: 94 Escort Wagon - Strange fuel cut off issue
Ok, so I found out how to do a KOEO test and how to reset the ECU.
Here is a vid that I made on how to do the KOEO test even when your check engine light doesn't work and you don't have an analog volt meter. http://www.youtube.com/watch?v=iovtX...ature=youtu.be The result that I got were: 116 Coolant temp sensor is out of range 111 Test ok / complete The issue still persists. I have no idea what is causing it right now... |

Re: 94 Escort Wagon - Strange fuel cut off issue
My problem seems to be solved.
The last thing that I did before the car had this problem was clean the IAC with WD-40. I read on the Internetz that a wet IAC can cause the computer to malfunction, but give no trouble code. So I went out in the morning (after it had a good 12 hours to dry off). It started right up! |
