Help!
My 89 BII quit running while driving it yesterday. It started losing power then eventually the RPMs dropped off until the engine quit. I towed it home and immediately checked the fuel pressure (38 PSI at the fuel rail). The fuel pump is only 2 months old. The way it stopped running this time reminded me exactly of how it quit when the pump went bad two months ago.
Today, I changed the TFI module, tested the coil (.6 OHM drop across terminals, and replaced the coil to distributor wire.
If I try to start it, it runs at low RPM for about 10-15 seconds then quits. It doesn't matter where the throttle is positioned and during this time it runs rough as if only on a few cylinders.
Where should I look next?
Help is appreciated!
