Bought a running used engine but its been sitting a while. Spins over normally. Replaced plugs , wires , coil ,rotor and cap. Hooked wires from cap to coil up. Hooked hot wire from coil to battery. Old cap was full of rust and on old coil. Not get fire to the plugs. Any suggestions ?
Engine is on solid mounts welded to the grame , ground wire coming off alt bracket to neg battery post
You need to grab a volt/ohm meter and check from the ignition post on the ignition switch out to the coil first and make sure you are actually getting juice out to the coil, then the distributer itself.
Im running straight from the battery to the coil plug . Jumping across the starter just to see if it runs.
Changed distributor . Put #1 at TDC still no fire. Changed coil in top of dist cap AGAIN. Still no fire
Changed rotor , dist , coil , plugs ,wires , dist cap , hot wires is to the battery side , dist is plugged in to cap.
Check the pickup coil. Connect an ohmmeter to the leads, one white other green(?) but it has a yellow connector that plugs into the ignition module. Move the wires , you should always have continuity, if open circuit at any point replace it. If not, possible bad ignition module. GM dealers used to have a module tester in the Kent Moore tools. Possible that an older dealership may still have one. If the module in the distibutor is a white cased Delco, replace it without a hesitation. They were junk, early 1974-76 but unlikey because most were replaced early on. Also check the wires to the terminal block for continuity. Possible they are bad but unlikely.
Is the distributor turning? How are you checking for a spark? Pull a plug lay it on the engine....^^^^^ is the coil button sticking out of the cap? Is the coil ground strap in place? Check for a ground at the distributor or hook directly to the battery.
