Hello peeps,

So I’ve been having trouble starting the FD and thought upgrading coil packs to the IGN-1A smart coils and upgrading the starter to the Banzai Racing starter would help but it still has trouble starting so thought I’d take it here to see if anyone can help. The weird thing is it would start if I jump start it with my portable but I don’t think the battery is the problem as it cranks but won’t start if I don’t jump it. I just got the battery not too long ago also so I don’t think the battery is the problem. Has anyone had this problem before if so any help? Thank you!

Low compression will cause the engine to not start if the cranking RPM is a bit low. Jumping will increase the cranking speed. Have you done a compression test?

I have not done a compression test but will soon, hopefully it’s not that but will see

There are starters available to fit the FD with higher cranking speed than the OE part - search on that. If the compression is only marginally low, that will likely solve your starting issue.

oh the cranking speed is good, installed the high torque starter upgrade from Banzai racing so I don’t think it’s that, I can send the video of how fast the cranking speed is when I get home

What's the voltage at the ignition with & w/o the jumper? Could it be a wiring/ground issue ? Plug wires, coil wires, etc., good?

Also, if the compression is low enough, even your "good" cranking speed may not be sufficient for starting.

I’ll get back to you on the voltage but it definitely could be my grounds, the coil and plug wires should be good though but my grounds could be redone

How fast is your cranking speed with that starter motor I'm curious
