76 2.0 ignition problem?, Won't restart after sitting for 15-20 minutes Options

[rd914]

Drove the car for about 30 minutes and parked for 15-20 minutes to get some food. Hopped back in and it won't start. The starter engages but no joy. Did it about 4-6 times. Had to push start the car (IMG:style_emoticons/default/sad.gif)

By the way, when I first start the car cold. It hunts excessively to almost where it dies then it settles a bit after it warms up. Still hunts but not as much. Not sure
if it is related to the issue I described above.

Appreciate any feedback. Thanks.

I spent several hours chasing the same problem on a customers car. Wouldn't idle after warm, had to hold pedal to floor, ran poorly with no guts. Cht had the proper ohms both cold and hot. Mps checked good, adjusted TPS. After much frustration, I unplugged the harness to the ecu and connected it to another of the same part #. The sucker fired up, idled steady, and ran much better than it ever had before. It now starts first crank every time no matter the temp. First ECU I've ever seen go bad. If everything is in spec, there will be no need to depress accelerator ever! Hot or cold!
