well guys… ive been fighting this no spark problem for months now. and im getting no fuel and no spark. my buddy let me borrot his da so i brought it home and took his main fuel relay, his ecu and his distributor. still no spark and no fuel. i went ahead and hooked up the fuel pump straight to the ignition switch so now i can hear the fuel pump pumping when the ignition switch is on. now im down to the no spark problem… any ideas?? i tested the connectors to the main fuel relay harness and im not getting any signal from a few pins… i forgot which pins. the diagram of the connector and fuel relay are at the shop.
thanks in advance guys.
I just had this issue so you have to look at the diagram on google see what pins are not responding ironicly i used a spare main relay from a odb0 Crx bam my fuel pump primed with out that same wire you speak of and it fixed a lot of my issues as for no spark could be distributor related or timing related… So with that being sAid this just happened
To me I would double and triple check the basics
Dizzy internals and timing
Grounds
Main relay
Multimeter the car and this process sucks but it more then likely will narrow down your issues to where you can find them and where you can start from
Agreed, recheck the basics. Check for power and ground to fuses, relays, then to the ECU, then from the ECU to the distributor. If your buddy’s DA is working properly you could check the same items on that one to get reference voltages.
