Re: 1987 k20 TBI Starting Problems. I know another "starting problem" thread

When I last left off I had replaced the cap, rotor, plugs, wires, coolant temperature sensor, idle air, rebuilt the TBI throttle body including new fuel pressure regulator, new injectors, new fuel filter, new battery, and new air filter.

After all that she was still hit and miss with starting and even when I did get her started it took a lot of cranking over and it was a struggle.

During the TBI rebuild I found the "J" vacuum port completely blocked as well as the vacuum line. After the rebuild I did not have a new vacuum line so it was disconnected for a few days.

When I installed the new vacuum line and tried starting her she fired right up without a struggle but died when I put her into drive and I couldn't start her again.

the update: I ordered a new ignition/distributor module and a new coil which I received and installed a few days ago. Its been three or four days since replacing the module and coil and she starts on half a crank to 2 cranks and idles smooth right away. She still bogs down if I put her into drive before she warms up but if I let her warm up for 5-10 min first and I can jump in and drive off with out any bogging. ALSO, its 20 degrees and snowing so its even COLDER than when I first started experiencing the problems.

SHE LIVES!

Thanks EVERYONE for all your advice and help.
