I have a Chevy c1500 with a 4.3L SFI (Z) /TH700R4 2WD.
This truck will start up fine cold or warm, drive it a few miles or all day never know when it will happen but the engine dies and starts back up. this may happen 2 or 3 times in a row in sometimes a few seconds to up to an hour then quits completely will not start again when this happens there is no fuel pressure the relays click on and off 2sec, I can't hear the pump run at all.
When it completely cools off like the next day then it starts right back up. I first noticed this stalling when I was pulling a fence out of the ground. I did not stomp the gas and slam the chain to conan jerk the fence out. I just pulled the truck agains the chain and eased the gas on till the fence began to give. This was lunges and stops and it stalled and started 3 times and then stopped completely it started the next day like it never happened.
After that I was trying to back the truck on ramps and I had to make several attemps to get the truck up the ramps and it stalled 3 times and quit, next day it starts!!!!
I replaced the intank fuel pump with an updated turbine version with the intank wire kit and a new filter. There are no codes from the ecm either. It runs strong when it runs... I checked all the wiring to find no shorts or corroded grounds.
I read in another thread that this could be the ignition module (Igniter) but this was on a 94 C1500 4.3L 5 speed, are these the same module?
The truck has quit 3 times and I had to be towed home each time..
Help on this issue would really be appreciated
