Did HEI conversion - cant get truck to start - no spark at plug...
So, I will spare all the long details but I am beyond frustrated after spending two days on a simple HEI conversion.
3 brand new HEI units later I have realized that it is not the part but something off on the truck... I have set TDC on #1 piston like 5 times. I wire my wires 18436572 in clockwise fashion. Rotor is always pointed at #1. All the text book stuff is right. I ran a brand new 12 gauge wire from the original fuse block from one of the two pins labeled ignition infused to the 12 v terminal in the HEI distributor (keep in mind I am on my third new one now, not junk yard stuff). Engine just turns over and never even attempts to fire, not even once. So I pull a spark plug wire and put another plug in it and point it at the spark plug in the block. I am getting ZERO spark on all three new distributors. Here are my questions: 1. I have a multimeter on the new 12v ignition wire I installed to the HEI and the wire has 12.48Volts with key on. 2. I had my wife crank the truck while i measured voltage at the 12 v wire I installed and it drops to 9.7 volts while cranking. I am at a total loss as to where to go from here. Seems like I have power to the distributor B+ connector but yet no power output from the coil to the spark plugs.... One thought is that the female connector I use has a plastic cover over it and is maybe not as tight as it could be - is this a thought to change connectors to the distributor male connection using metal only connector??????? Is 9.7 when cranking not enough yet the battery and connnector sit at 12+ volts when not cranking with the key on...... HELP!!!!!!!!!!!!!!!!!!!!!!!!!!! |
