help! car randomly dies
help! car keeps dying
ok first off- 93 prelude jdmh22 swap, tuned on crome(minor issues have occured but not enough to make it die like this)
ok driving home i noticed that the tach would jump if i decided to get on it a litttle bit. say over 3500 to 4000 rpm. nnot slight like all off or where it should be. then i get in my neighborhood and it dies at a stop sign. so i try to restart it and i can hear the pump priming. cranks but no fire. so i let it sit for a few minutes while i go get some tools and return on my bike. take the dizzy cap off and everything looks fine. put it back on and it starts up. so as im breaking down the nike to go home it shuts off again...
so i wait and try to start it and CEL pops on.
code 8 - something with tdc or cyp. cant remember exactly right now
code 15 - ignition output signal
code 22 vtec pressure valve.
so reset ecu and try again and it starts.
literally 15 houses away from home it stps again.
so i wait and eventually it starts and i get it home. after an hour of being in my neighborhood
so now... where would you start?
i have recently converted to external coil(msd) and replaced the dizzy with a brand new rich porter(?) since the old one was leaking around the main shaft.
so now i feel you should know everything needed to help me diagnose this horrible issue.
please help me out
thanks

Re: help! car randomly dies
Not sure if this helps or not, but i had a '93 H22 Lude do a something similar. Mine would turn off if i had driven it for too long at a stretch. It would not to anything when i turned the key, the pump wouldn't prime, it wouldn't even click at me. Nothing. The first time this happened i was in a hurry so i left it and hoofed it where i was going. I came back 2 hours later and it fired right up and drove like nothing had happened. This happened a couple more times before i scrapped the car for other reasons, but right before i scrapped it we had it pretty much narrowed down to a short in the fuel relay. Now since i never actually checked it out it could have been something else entirely, but i just thought i'd throw the idea out there for you to check out.
