All these ignition problems didn’t exist before pulling the engine and resealing.. anyway I have no spark on all the driver side coil pack cylinders (4, 6, 7, 1) and I can’t seem to figure out why. New coil packs and tested fine, tested igniters with test light and they both sparked strong, new plug wires, distributor cap, and plugs. Crank shaft sensor was initially creating a no start problem but after fixing that wire, car starts right up even on 4 cylinders. Sensor wire to ecu looks good as well. I just can’t seem to understand this odd problem…any help is greatly appreciated!!

I had this happen on my Cressida recently (1uz swap) and it turned out to be a shot coil... if yours test good, make sure all your connections to and from that coil are good. Otherwise, if all checks out well, let us know what CEL codes you're getting and we'll see what we can do to help!

hey, sorry for the late response I didn’t see that I got a reply. The wiring to the coils look good and I did test with multiple coils. I’ll try to get some codes soon!
