Hi
I have an '87 13B fuel injected (the Grassroots Mag RO-Sit) installed into a Triumph spitfire. It has a half bridge port and puts out 193 horse at the wheels. Today it backfired and died. I have had no luck restarting it and had it towed home. What do you feel is the problem? It had a low RPM miss forever. What engine can I put in that I can bolt on my auxiliaries and still get 200+ horse at the wheels? I also need to make it somewhat quieter.
Thanks bunches

You have the Ro-Spit? I hate you. I subscribed to their magazine mainly to follow the 20+ part series on that car. In fact, just last Wednesday I was having dinner with someone who said he almost bought that project car and regretted not jumping at it in time.

As I recall, that's a TEC II system? You might want to check the MAP sensor, in particular. Use a stethescope to hear if the injectors are clicking while you are cranking, and shoot some carb cleaner in the intake as you crank it to see if it will light off then. A compression check would be a very good idea too.

Let me know what happens.

Well it started this morning 8am 2/6/06. Ran for 1 min. and died. Finally started again at 4pm ran for 1 min and died. Not to start again today. It's the TEC 3.
For that min it ran good. Will hook up the laptop to it 2moro. Will keep you posted.

Ah, TEC III, now we're talking. Rotaries have never loved the TEC II, but the TEC III is great. Try turning off warm-up enrichment...I bet it won't run at all, then. If so, it would indicated a lack of fuel. Prime suspects: MAP sensor, big vacuum leak or perhaps the fuel pump. Check the vacuum and check the fuel pressure, to start. Sounds too quick for vapor lock. Good luck.

Very Happy Very Happy Very Happy It was an intermittent relay that sent 12 volts to the coils... dang Lucus is still alive in all British cars.
Thanks for the help... Hope to have it at the Mitty this year. Mazda is the sponsor.
