Question Asked: Truck run fine at start up, then dies, weird computer readings.
September 11, 2013, 04:04 PM
The truck run when first started, will idle for about 30 seconds and then dies. I have my Genisys hooked up and the coolant temp and air charge temp will go from normal to -198 degrees, the battery voltage will drop to 0 and the RPM will drop to 0 then they all go back to normal, then drop again. Have replaced the temp sensor, the hall effect in the dist and the O2 sensor. Have no idea, please help. It will start back up but I have to cycle the switch a couple of times then it will start and then die after a couple of seconds.

The truck will run for a little while then stall out. with my genisys hooked up I can watch the data stream and the battery volt will drop to 0, the RPMs drop to 0 the air intake temp and coolant temp bounce from normal temp to -198, have replaced the pickup coil in dist, coolant temp sensor, O2 sensor, tried a different computer, nothing helped. HELP please
Question Asked: want to die
August 14, 2013, 02:26 PM
when you first start the engine it runs good, after it go from fast idle to idle it will run ok for a bit and then wants to die. it sounds like it is gasping for air. If I unplug the MAP sensor it goes to high idle and runs ok, but when I plug in back in it want to die again. have changed MAP sensor, O2 sensor and ignition module. any other ideas?

when the engine misfires the fuel from the injector skips, like it stop injecting fuel. I have replaced the dist, cap, rotor, plugs and plug wires. any ideas?
