Vehicle is ‘87 ram with a stroked 340. Can’t get it to fire. I have a Mallory Hyfire ignition box and matching Mallory unilite distributor.
At the end of last year I Tried to start it and the battery was dead (It had been running fine the last time I drove it). Boosted the battery but it wouldn’t start. Tried 2nd battery and same thing. It was getting some spark because it was on the verge of starting but just not quite enough. I left it for the winter and now I’m trying again.
Same condition. I tried the manual troubleshooting and followed the instruction to check to make sure the box was working, basically disconnect one wire and ground it. Should get a spark which I did, but is seemed very faint. Nowhere near as strong as get from the Mopar OEM box when I hold the coil wire to metal to check for spark.
Called tech support, they said it was the optical sensor on the distributor. I just swapped that and still getting the exact same condition. Close to starting but just not enough.
When I pull the coil wire and crank the engine I can’t see the spark jump.
Any suggestions?
