1988 RX7 Won’t Stay Running
1988 RX7 Won’t Stay Running
Hello all! Total newbie post here, but I’ve been searching and searching and I’m not confident I’ve solved my problem.
I just purchased a 1988 RX7 this week. Supposedly had been running a few months back before an engine fire (bad pulsation dampener) and had been fixed.
The Problem: The engine fires up (see video), but won’t stay running or idling.
Attempts at a Solution and Tune Up:
1. New fluids
2. New fuel pump
3. New air filter
4. Checked for Vacuum leaks
5. New battery
6. Jumped the new fuel pump, wiring and pump are good
Guesses:
1. Vacuum Leak from BAC or elsewhere
- I took the yellow tape off and the car wouldn’t even fire, I added it and it will fire up and run with the throttle being pulsed. So, vacuum leak?
2. Low fuel pressure (hence the new pump, which is good and I can hear running)
3. Something else entirely.
Ive attached pictures of every disconnected hose or wire I could find, most leading to dead ends or being overflow hoses. Any help would be appreciated, I’m moving tomorrow so I was hoping to have this actually running! Thanks all!

The hose down below near the exhaust manifold is for the EGR I believe. Connects to the backpressure tube coming off the cat. Keep it plugged since the EGR probably doesn't work anymore anyway.
