90 EF ZC swap fried the ecu got new want run!
I bought this car running just needed some clean up and the proper dizzy. she has a shoty wiring job but it was working until something grounded out and fried my ECU. I have got 2 more since then they both work but still nothing. All fuses good, relay good i have 2 of those. The relay is not clicking a 2nd time meaning my rail is working but the pump is not priming or anything for that matter( it does work i jumped it). The CEL is on was not before and im also not getting spark. The car was sitting in idle when my friend put her feeet down by the ecu something grounded and my car just shut off. I have a new/used working ecu P06 installed and i cleaned up the jumper harness but she still is turning over but no spark and no fuel( I have a fuel pressure guage installed on the filter) and still showing CEL? DEAR GOD SOMEONE HELP ME PLEASE!!!!!! 5 WEEKS OF THIS ****!!!!!!!

- Needs new distributor
- Bad wiring job
- Fried ECU
- Relay good
- Relay not clicking 2nd time
- Fuel pump not priming
- CEL on
- No spark
- No fuel
So it's a swap, with a bad wiring job? And the CEL is on, and it needs a new distributor? No spark or fuel? What exactly do you need help with? Sounds like a real gem.
If you're throwing a check engine light then it would be wise to disclose what the code is. Also it would be wise to disclose which specific ZC you have and which specific ECU was fried.
That's why it's important to disclose all details, from your last post by default you have either a jumper harness OR more hack wiring at the ECU because both ECUs you have listed are newer than pre-OBD and your car is set up for pre-OBD. That right there is another possible source.

car has mpfi conversion, obd0-obd1 jumper, obd1 dizzy convert(do i need a td43u?), was running p72 chipped on a 2nd gen JDM ZC 1.6l dohc. I have a td03u and bought a mpfi to obd0 dizzy convert from Rywire(being shipped do not have yet). From what I have read my ZC should be running that.
AS 24TEN says, first find out what the CEL code is
I assume the ZC is DOHC? - if you are using an OBD1 ECU, which it sounds like you are, then you need the OBD1 TD43U distributor - you can't use the TD03U OBD0 distributor with the OBD1 ECU - the P06 ECU will run it but you would be better off with the P29 ECU that it should have - the P72 VTEC ECU is not what you want
