1990 Z32 N/A Won't start!!

[TimmyZZZ300]

Ok, so I had a coolant leak under the upper plenum, I removed the upper plenum and repaired the leak. I put everything back together and now the car will not start. It will turn over and it has fuel pressure and spark. At a loss hear, I have heard rumors of issues when the harness is undone, but never an exact solution... any help would be great.


Thanks,
Timmy C

Check for any ECU codes. You want to re-check all of your connections including all coilpack connectors, injector connectors, ptu connectors, cas connector, iacv connector. The main issue with removing the harness is that all the 20 year old connectors are very britle and break off, causing a poor connection when you reconnect everything.

check and clean all the injector and cop contacts, they tend to corrode and once you unplug and replug you can loose contact
