Driving home one day from a three hour trip to central Oregon, Car started to bog a little bit, I kept going for like 10 mins then it finally just shut off and wont run now. It wouldn't even start then I replaced the fuel filter,Plugs,Wires, Dist cap and rotor and now if I crank it over it revs to like 2500 and then dies immediately. I'm really confused as to what to do, It has enough spark to start, enough fuel to start, but it just wont stay running. ANYONE have ANY ideas?

1991 Si Crx

 

My '90 Si hatch would start and die immediately after, like you are saying too. I replaced the main relay and it fixed the problem. Its roughly around $35-$45 I believe.

 

Main relay is like $.35 to $.45 problem if you can work a soldering iron...

Do you have a fuel pressure guage? can you see if you're loosing pressure? got an extra coil handy?
