Sounds like the throttle body needs cleaned, remove the air inlet tube from the throttle body, hold the throttle open and clean the inside of the throttle body and butterfly with some carb cleaner and a rag untill there is no more black sutt.

I agree with your statement that you have a fuel leak. Perhaps you also have a question.....

This is most likely an issue with the ignition switch. $20-$30 for a new one on ebay.

There are several fuel connection points in the fuel lines which run from the tank to the fuel pump through the left frame rail. Check these connections and look for any damage to the fuel lines. Additionally, the fuel filter on the left rear of the engine has a water bleed off knob on the bottom. This knob could also leak by the left front corner of the cab.

let me say this plain REMOVE THE BATTERY CABLES and let sit for several minutes to discharge completly before unhooking pcm connector (or you'll be buying a new one) clean using electrical grade contact cleaner (not good to get on your skin) both sides male and female pins let dry completly use diletric grease on rim around connector try and not get it on pins to waterproof the joint reinstall locking clamp tight! connect battery back + last test engine and trans for shifting

This could be a few things. The freon could be low, one of the switches (high or low pressure) could be bad, or you could have a bad compressor clutch. You can test the clutch by checking for battery voltage and ground at the two pin connector with the A/C on if you have both power and ground, then the clutch is bad. You really should start by hooking up pressure gauges to the A/C ports to check the pressures, and these vary depending on ambient temperature and whether the A/C compressor is engaged or not. I am willing to bet that the freon is low though and may be just as simple as recharging the system.
Hope this helps. Good luck!

only one fuse block

Check the fuses & fusible links. If good then the switch is bad.

I got a code p1191 when chked with a diagnostics machine,where is this exactly for me to chk.It has died on the road with low rpms

Release the charge a bit at a time as the high head pressure switch is stopping the unit from working.. Best have it done in an ac shop.
