Sorry, I didnt know the car. Im in Boston, it was an hour south of me. From the ad and the pics I got from the seller, looks like your buddy got a good deal.:nice: Is it still in Mass?

I was wrong, the SNEEC is definatly what was causing it to stall on a cold start. The time it stalled without the SNEEC, I had left the ECT connector unplugged. I messed around with it figured out the different things that made it run right and what made it stall and this is my observations...

Interesting, so it was the fact that the ECT was unplugged, and it went into failure mode, that caused it not to stall. I see, so I guess Im back to square one? But the time it started up and didnt stall, it wasnt throwing a code 51. Im not positive, but I dont think it was throwing any...

Is 4.71 volts correct for the ECT voltage with the connector off? Shouldnt it be 5.1 volts, the same as Im getting from vref. I still feel this is the source of the stalling problem. The car still stalls when the sneec is out of the equation. The sneec wasnt causing the stalling. The ECT...

I took the connctor apart and removed the ECT pin Put it back together and now It tested at 4.71 volts. WTF The ACT pin still registered 3.98 volts. I removed ACT pin and It also tested at 4.71 volts WTFx2 This entire time, I have had the SNEEC IV datalogger hooked up, so I decided to remove...

Resistance across the unplugged ECT sensor is 80.9 K Ohms. It warmed up a bit here, its almost 40 degrees in the garage. Engine hasnt been started for a few days, its at ambient temperature. 40F All the resistance tests above (Including the 97K ohms)was with the ECT and ACT and the...

Sorry, this is what you meant. I will do this right now

For clarification, I plug the ECT sensor in, I disconect the eec connector and then check resistance between the ECT pin7 and the SIGRTN pin 46? Should be less than 10k ohms?

I have 2, the original 8LD and a remanufactured cardone that I just bought. They both produce the same results. No one that lives close to me has a stang I can pirate a MAF computer from.

If I connct one end of the volt meter to pin 7 (ECT)on the computer, and run the other end of the volt meter to the negitive side of the battery,then disconect the ECT sensor, and I get 3.98 volts, doesent that take the ECT wiring and connections out of the equation? Since pin 7 should be the...

Im a little slow on the uptake sometimes You mean on the ECT and ACT circuits? A voltage drop test? Found a good article here How To Perform A Voltage Drop Test - Help With Automotive Circuit Diagnosis

I will measure all the sensors that use vref. Measure between vref and sigrtn? The problem sensor will have 5volts in and less out? BP sensor TPS EVP Did I miss any? I test them KOEO?

It must be something inside the EEC, I think I educated myself about how the ECT circuit works. I checked the resistance between pin 7 and the ECT connector and got 1.5 ohms, thats with the computer disconected. I plugged the computer back in and checked the voltage KOEO at Pin 25 (ACT) got...

ttt

11.95 volts at pin #1. Same as the battery voltage, which I beleive is correct. The values in my first post are at the connector, KOEO, with the sensor disconnected Im just a humble civil servant and my grasp of electrical theory is tenuous at best.:shrug: I found this explanation of how...

There are 2 wires on the connector, one going to pin 7 on the computer, and one labeled signal return. There is no voltage from signal return, and 3.98 volts from the pin 7 wire. Is this correct? Should the pin 7 wire be around 5 volts, vref?

Are these the correct values? Ford Fuel Injection Engine Coolant Temperature Sensor (ECT) Im having a similar problem. My 88 cranks and starts, and then after runiing for about 5 seconds, it stalls.
