Also check the power wire from the coil to the ECU. It can look good at the end but be corroded and broken a few inches back.BTDT.

Subject: Broken down travelers need help ASAP

I have a couple from Colorado broken down in their 91 automatic all
stock hardtop. Having their van towed to my house in Mystic,CT.
Van died suddenly with no warning.
Fuel pressure was fine but have no spark. Replaced coil with new Bosch
one and installed a new rebuilt distributer. Still no spark out of coil. Have
battery voltage on black wire side of coil. Need to test further and could use some advice.
I am afraid its their ECU but don't have a spare and time is important
as they need to be back on road ASAP. Does anyone have a spare
ECU for a 2.1 that we could borrow or buy? I didn't realize that I gave
my last one away. I am going to run down the ECU plug with my meter
doing all the checks in the fuel injection repair manual.
If there is anyway you can help with an ECU please let me know ASAP.
I want to get these kind folks on the road.

Bill
