Expert:  Chad Farhat replied 1 year ago.

when it does die on you and you try to started and it does not start , does it crank and no start or no crank

if it does crank and no start at that moment have you tried to see what are we missing at that moment fuel Or spark or both ?

the a/c is loading up the circuit and it is effecting the fuel or the spark or both ?

Can you check and let me know


Expert:  Chad Farhat replied 1 year ago.

Its..2.2l engine
Customer: replied 1 year ago.
Any ideas
Expert:  Chad Farhat replied 1 year ago.

i will start with a/c control module and check the back connector and the module itself if you have not already

that is low mileage on truck, the a/c circuit is loading up another circuit and killing the truck, if the a/c control head dont fix it you a wiring diagram and see where the a/c circuit crosses the fuel & ignition circuit and test for short at the time a/c is on

Customer: replied 1 year ago.
Ok....I will try that
Customer: replied 1 year ago.
Would that be a relay
Customer: replied 1 year ago.
In the fuse panel
Expert:  Chad Farhat replied 1 year ago.

no not a relay , that is the a/c control unit inside the cab, it is inside the dash the one has the control heat /temp fan etc... so you turn on with
