[SLow_POke]

you're not getting spark or good enough spark? and u even swapped to a known good diizzy AND wires? with the same issue?

[94_teg_ls]

yes pulled it off my gsr no spark at all put the dizzy back on my running car and drove it home so its just that car

main relay or ECU

[94_teg_ls]

dont say ecu and we have fuel and spark every where else so its not relay

Check the spark plug for the cylinder, maybe the gap clearance is not correct or the spark plug has been fouled. Oh yea, make sure your spark plug wires are in the correct sequence/locations on the dizzy. Check if your fuel injector plug for that cylinder #4 is snug and plugged. Keep us updated.

i have a boosted del sol and i let it sit for a good 4 months. then cranked it. it turned out the connection on the #4 450cc dsm was bad. so pull your injectors,clean them and put them back in.they get clogged if their not run. worht a shot anyway.and change the fuel filter to help the cause. hope that helps bro.btw nice setup

What do you mean no spark in number 4 ? Coming out of the wire or that cylinder is skipping and you just pulled that wire off?

If it's not getting fire from the wire but the dizzy cap and all works as you stated you put it on your car and ran fine , what about the wires?
