|  90 fuel problem
My 90 C4 350 v-8 has started to die when it gets hot. I buy gas from the same station. I have replaced the plugs, plug wires, module, rotor, cap, and coil....fuel pressure = 40 lbs. It tries to start but acts like it is not getting any fuel. Will start after it cools down(the next day) any ideas? Thank you for your time Bobby | ||||||||||||||||||||

Have you checked the fuel pump itself? Don't know the procedure, since I had it done. Bet someone here or Chilton's/Hayes has it available. I had a similar problem and all seemed well, but the fuel pump showed a bizarre waveform when it was checked. Seems they get hot and need a pretty much half full or better tank to stay cool. Replaced the pump. Car fires every time. It's an easy, cheap, repair. | ||||||||||||||||||||

HI there, Check your fuel injector resistance, it sounds like 1/2 are shorted. 16.5 ohms is the resistance. Any more than 1.0 ohm, can create the condition. Allthebest, c4c5 | ||||||||||||||||||||
