datzenmike Posted April 12, 2022 Report Share Posted April 12, 2022 Pull a plug wire, stick a plug in the end and lay it on the valve cover or something that's grounded. Have someone turn the engine with the starter..... got spark? or not??? YES..... nothing further required NO...... Do the same with the coil wire. Got spark? YES.... problem is probably the rotor or distributor cap. NO..... check for power on the coil positive terminal. YES..... there is power at coil. Briefly ground the coil negative terminal and release. Got spark???? NO....... power, find out why YES..... there is now a spark, problem with the EI module. Check that distributor is well grounded. NO...... spark, coil is bad 1 Quote Link to comment
nissan720 Posted April 14, 2022 Author Report Share Posted April 14, 2022 thanks Datzenmike that fixed it. Changed the EI module. had one of those aftermarket ones up there .Found one off of a 1981 datsun 210 about 2.5 hours from my house. And now it works good!! 1 Quote Link to comment
