Help!!!!! 95 escort wiring diagram?????

[dwbailey]

I made a MAJOR screw up and cut the wires to splice in a new connector to the Engine Coolant Temp Sensor and forgot to mark which wire went to which and of course the wires don't match on the new connector. Does anybody have a wiring diagram that tells? The wires in the harness are green with a black stripe and the other one is green with a yellow stripe. The wires coming out of the connector are black with a white stripe and green with a yellow stripe. Someone that has one of these cars may need to, if you are so kind, take a quick look at your connector and let me know which one goes into the right side of the connector and which one goes into the left. I CANNOT believe I made such a basic mistake! I hope someone is watching today and can help. Thanks guys!

Just curious-does the connector you cut off still have the wires sticking out?

Is this a 1.9L?

Actually I had previously replaced it and of course that time I paid attention. One of the connectors wasn't crimped good and the guage was doing what it had previously done (jerked around like it had a short in it) so I decided to replace them with the paddle type and got in a hurry. I just reconnected them with the green and yellow stripes together and the green with the black stripe and the black with white stripe together. Started it up and let it begin to warm up and the guage started moving in the right direction. Not sure if it is as simple as if it were backward the guage would go in the opposite direction or not? Thanks for your as always most excellent recommendations.

Yes, 1.9

Well replacing those splice connectors seemed to fix the erratic needle jumping around. On another note though, what would you think would cause the engine at a red light to go from a smooth idle to a dead miss for a few beats, back to a smooth idle to a dead miss for a few beats, etc? I changed gas stations, ran fuel cleaner thru it and put some HEET in it and drove it awhile. Disconnected the battery to reset the computer and ran it and I thought I had it whipped. NOT! Doesn't seem to be doing it so quickly now but I haven't driven it enough to tell. Would a fuel pump going out cause that type of reaction? For almost a year now I've had to turn on the key let it click, turn it off and let it click and then start it. If I try to start it without doing that at least once, it'll crank for awhile and sometimes too long until I stop and let what I assume is the pressure to build up and then it'll start. Was thinking maybe the fuel pump has been slowly dying and with this most recent behavior that it is getting closer to dying. When you drive along it runs really smooth. Just has that dead miss behavior when you come to a stop at like at red light. Any ideas? Thanks.

I think the erratic idle at a stop sign is due to faulty wires or plugs. However, you are right. A fuel pump not putting out enough pressure will do the same thing. Your fuel pump is on the way out. Actually the fuel pump should have about 5 lbs. more pressure at start up than while the engine is running. Take the vacuum line off the fuel pressure regulator by the fuel rail and see if it has any gas in it. If so, replace it. Check the pressure at the Schrader valve. It should have about 35-40 lbs. of pressure with the engine not running and 30 to 45 lbs. of pressure while the engine is running.

Thanks Dave. Gonna have to take it into a garage and get it checked. I don't have a guage to check the pressure and of course there is the time. It's my 18 year old son's car and I am so covered up that I just can't seem to find time to keep up with the day-to-day juggle. Hopefully this garage in town will be honest. Haven't used them in the past. My son drove it to school this morning and said it did fine. Hmmmm.......

Well he actually came back and said he didn't have to stop on the way to school so I'm sure it is still doing it. Taking to garage this afternoon.

It just occurred to me. The sensor with two wires in not for the gage. The single-wire sensor works the gage.

That's weird because when I fixed the wire that was barely hanging in the splice connector, the guage started working again.

Dropped it off at the shop. Son said that it was doing that jerking worse when he was coming to a stop. Just hope its not something like the valves or something major.

The two-wire sensor deefs coolant temp info to the computer. Right next to that is a sensor woth one wire. That one works the gage. Let us know what the shop finfs

Seems so weird that when I fixed that connector, the guage started working and stopped the erratic behavior of the needle due to the short in the splice.

The guy at the garage gave up. Said he didn't have a scope and couldn't pinpoint it. Said he took a plug wire off of the #2 cylinder I think it was because he said it was that one that was the one that is missing. He said he listened to the injectors and that they didn't sound good but couldn't say for sure that is what it is. Said it could be a valve too but couldn't confirm that. He didn't do a compression check (why I don't know) nor a leak down test so can't say what that would have shown. I don't have a guage to check the compression so I have to wait on a guy I know that does to come by tomorrow after work and do the compression check and a leak down test. Also has a stethescope and will listen to the injectors. The guy at the garage said when you rev the engine up the miss seems to go away but at idle, that is when it has that dead miss in it. Any ideas?
