After recently completely changing out a 1992 cab to a 1995 cab, there insn't anything i dont know about this year of cab (89-95). i had this problem once and i had to make sure that my mass air flow sensor was completely hooked up, I only have the 22re motor, so there is a large tube from the intake to air filter and that tube has to be completely hooked up, that air flow sensor is like a throttle sensor, your pedal opens the air with a "gate" on intake and the sensor senses air flow to give more actions after that, if its disconnected, it will only run while pumping the pedal, and in some cases not even that. any other questions email me kc0tdw@kc0tmo.com
No. The ECM detects the engine is not running and shuts the pump off after a few seconds.
Your 1991 4.3 S10 starts for about 3 seconds then shuts down because it is faulty. Take it to mechanic to have it checked.
The alternator is most likely the problem
If you are thinking of an inertia switch, no.
it has a timed relay. Toyota used them for a while too, people complned and they stopped using them. as long as it shuts off in less than 30 seconds you are ok.
1991 mitsubishi eclipse 2.0L starts 2 to 3 seconds later shuts off
If it's running, then it shuts off and when you reboot it, you will find it has been reset. If its already off and you take it out for only a couple of seconds, it does not reset. The same applies for any custom firmware.
You have a problem
I would start with the Pickup Coil and the Crank Sensor.
The computer detects whether the engine is running and turns off the fuel pump in about five to ten seconds if the engine didn't start.If the engine starts and the fuel pump shuts off anyway, check for diagnostic codes, verify that the relays are working properly and check that the computer is able to determine when the engine is running. BTW, it's probably NOT a problem with the computer.
Check the car computer for error codes, google them.
Check ur cps sensor
