    Is the fuel filter clogged? Does the fuel pump turn on (assuming it is fuel injected)?

The 98 Bravada has the factory security system that will cause the fuel pump to not engage (in case someone tries to steal it). I have also had this problem. Try turning the alarm on then off again and see if that solves the issue. That will get you by until you can have someone fix it ;)

Chrysler p0456 code


Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Evaporative Emission (EVAP) canister or fuel tank leaks
- Evaporative Emission (EVAP) system hose leaking
- Fuel tank leaking
P0456 Chrysler Description The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage. During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

Just cranks over geting fule has spark plugs wet 1/2 tank of gas


test to see if you have spark with a dry plug if so you may need to dry your cyl out due to you may be dumping to much fuel. a soaked plug will not spark.

The fule pump went out i replaced it the cars geting fule and fire but wont start


You say you have spark, and fuel, but you also have to check for compression....Get a pressure guage and check each cylinder, or atleast 3 of them..It is very possible that your timing belt has popped..
