2002 chevy astro van - 1995 Buick Century

Is it a strong spark at the coil? If it is to weak it won't travel through the wire.

Check your TPS Sensor. My 1995 Chevy Astro Van did the same thing and I thought it was the fuel pump but I was wrong.

The power for the data link connector is from a 25amp fuse Number 7 in the IP fuse box. As long as the check engine light is on the computer has power.
The main computer power is from two ECM fuses in the box near the battery.
The fuse locations should be in the back of your owners manual.

loosen fuel lines at throttle body when turning key to on possion , careful not to spill gas all over engine, do you hear fuel pump running and try to put at least 4-5 gallions of fuel, you could try a (LITTLE ) shot of starting fluid ?good luck hope this helps.

Underneath where the motor and trans.meet.

there is no relay power from control panel through pressure switchs to compressor

have system scanned to get trouble code

you must remove the controlles and use a test light to dee if it sends poer to the fan it also can be the resistor pack for the fan speeds
