The truck will start for 2 seconds then die.

Question:

I have a 1998 Chevy S10 pickup with a 2.2 4 cylinder engine and automatic transmission. The truck will start for 2 seconds then die. I would like to add that the security light is on.  I tried unplugging battery to reboot computer .

Answer:

If you can hold the key in the start position and the engine continues to run, then you need to replace the ignition switch ( not the key and tumbler, the ignition switch ).

If it does not continue to run, Then you will need to have your fuel pressure checked. Fuel pressure should be 41-47 psi. If less, then you need to replace the fuel pump.

The Security light should be on, this is normal… unless the key you are using no longer has the chip in it… The security light will come on and goes off after the vehicle is running for a few , then the lights go out ….. the check engine light should come on too, along with the seat belt light…. all normal.
