I swapped my 89 crx dx to multi port and h23a vtec and it ran for a few days but in limp mode and was reading a crank sensor code. It died on me on the highway on saturday so i figured it was the distributor and swapped it out. Now it seems to have no spark and will not start. Timing is on point and it ran decent aside from being in limp mode and it cutting off. I am losing hope and need help on where to look. I was running an obd1 p75 ecu and now put in a p72 to see if that was the issue and nothing happened. Please help
