What does the 3-10 code mean for the 91 chrysler new yorker 3.3 litre

Check fuel pressure and see if the pump is good

Take it to a local mechanic and get them to have a look for you as it sounds like the autochoke cold start temperature sensor could be defective

11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles
13 No change in MAP from start to run
14 MAP sensor voltage too low

Hope this helps. God bless

O2 sensor need be replaced.

Good luck.

could be fuel pump

Obviously you need to replace the bent pulley,
more than likley the belt will need to be replaced
also.

could be a bad fuel pump relay or fuel pump.and a bad ignition coil will cause engine to stall when it get hot.

I didn't know that 91 Chrysler New Yorkers had clutch cables. I have or have had several of these cars and have never seen a clutch cable

could be the fuel pump a bad coil or pick up coil located under the cap and rotor fuel pressure should be at least 35psi.
