Re: Can't find misfire
The fuel pump going back down to zero after the pump stops is normal. Some TBI units have a pressure bleed hole in them the bleeds the pressure off. A steady 11 PSI running is good enough.
Many of the bigger auto parts stores in my area will test the distributor module for free if you bring it in. The test results from these stores are not always accurate, and some times the will say the module is good when it is not, but for a free test that may find the problem it is worth a try.
Make sure when you install or reinstall the distributor module that you use heat sink compound under it. The compound helps dissipate heat from the module. Without it, the module will fail.
