So this is a conversion from a carb which was running great with the new FI. I had just installed an AFR meter and was adjusting the AFR to about 13:1 during a 30 minute run. Stopped at the grocery store and had a crank with no start after a 10 minute soak. The harness is newly fabricated, rebuilt AFM from AutoAtlanta, gas in the tank, I do have spark, fires with starting fluid, fuel pump runs when vane is moved, have power to the ECU, no difference with second ECU, voltage to the injectors with key on, new Pertronix III dizzy with Flamethrower III coil, have fuel pressure (40 psi), throttle switch doing what it is supposed to, AFM voltage output varies with movement, Air temp thermistor in AFM is in range, CHT reads 2.2 K ohms.
I'm kinda running out of ideas. Got any???? Thanks! Ray |

QUOTE(JeffBowlsby @ Jun 20 2019, 05:03 PM)  Our own Jim Hoyland documented the dual relay test protocol here All, Thanks for the tech support. I put the 4 channel scope on the dual relay and saw a lot of bad behavior. Then I popped the relay open and found the corroded mess below. I bought the relay from CIP1 in early May so it was damaged before I received it. They obviously have a quality process problem. My refund request is in and a new one is on order fro AutoAtlanta. It is surprising that it ran the car at all. (I also had to pay $90 to get it towed home.) Attached image(s)
