I do not know what is going on with this ECU, I just got it back from Nistune because of some issues it had due to a firmware update. I'm pretty certain it is the ECU. The car ran pretty good Friday when I got the ECU back from them but had a couple hiccups, Saturday those hiccups turned into a full blown issue. Friday I had the car sitting and idling, I wanted to make sure the e-fans were going to come on before I took it out for a test drive, it had been sitting a while. It had idled about 20 minutes and just shut off, that itself is not all to odd its been known to do that from time to time. However this time I kept hearing the fuel pump surge in rapid pulses, I opened the door to get the key and heard the fuel pump relay clicking in rapid fire. I've never had it do that. It only happened once on Friday, I went out for a quick 10 minute ride came back to the house and shut it down and left for work.
Saturday I went to drive it to a friends. I started it up, and it idled for about 2 minutes then did the clicking thing again. I had to shut the key off and wait for about a minute then it started right back up. I started it up again and it idled a few more minutes then started to sputter and blow huge amounts of black smoke. It flooded completely in just a couple seconds, I had to replace the plugs to get it to run again.
Today I went out and jumped the fuel pump circuit to keep it running. I thought maybe I'm having a grounding issue. So with the pump jumped I started the car, it ran for a few minutes then just shut off and wouldn't start back up, just like before but minus the relay clicking like crazy. As for the flooding I swapped the MAF as well as the CHTS, Nistune is reporting no codes out of the ordinary, yet it is still flooding periodically. Sometimes it does it right away sometimes it will run for a while before doing it. I'm completely stumped. I'm thinking maybe the ECU is dying. I have another 88 ECU around here somewhere that came out of the car. What would it take to transfer all the Nistune hardware into it?
I made a video of the car running a bit then shutting down with the clicking so you could see exactly what I'm talking about. http://www.youtube.com/watch?v=LL30XazaM9Q&feature=youtu.be[/video]]
Anyone have any ideas on what could be going on?
