The problem:
I am putting 1990 GM TBI system on a 1965 chry 273. When I turn on the Key the pumps start and injectors start pulsing fuel the pump doesn't shut off after 1 min this with out cranking the engine over.
The Fix:
The Dist wires from the 86 electronic Chry dist were in the wrong positions on the 7 pin GM ing module.:whoops: Swapped the wires injectors stopped pulsing the engine started and ran much better than the carb ever did.
Still need to connect Knock sensor, and get O2 sensors bosses installed and connected.
The GMC used a hot fuel module to limit pump power during ko and of course I didn't get that from that truck at the time.
The Stuff:
86 Chry Electronic dist, 88 Dodge van 75 Amp denso Alt, 1990 GMC Throttle Body, ECM, ing module, sensors, wiring harness, fuel pump high pressure Carter P5001 20 PSI 50GPH, Low pressure Fuel Pump Airtex E8090 5-9 PSI 30GPH, homemade fuel surge tank.
Installed on a 1965 Barracuda 273 auto I know its not a truck or 4x4 but the toy before this one was a 51 Willys 1Ton P/U.
