It's your Electronic Control Module (ECM). There is a short in the computer. You're going to have to replace it. The same symptoms occurred in my vehicle, had a mobile mechanic come to my house and fix the problem. Quoted me $350 for parts (used) and labor.

Check fuel flter at fuel pick-up intank (looks like a small wire sock). Remove fuel filter and fitting at fuel rail. Blow out fuel lines w/about 35lbs air press. Ck electrical @ relay - should be 4 connectors - one is key on hot/one is always hot/one is ground and last is hot to fuel pump. Good Luck

Keep in mind that you have several components there:
- Fuel Pump Sender Assembly,
- Fuel Pressure Regulator,
- Fuel Rail Assembly, and
- Fuel Injectors.
1.- Fuel Pump (Sender Assembly) - TESTING
Refer to the accompanying charts for fuel pump diagnosis and testing.
The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

2.- Fuel Pressure Regulator - REMOVAL & INSTALLATION

NOTE: Before removing the fuel regulator assembly, place a clean shop towel under the regulator to catch any fuel drips

don't do it. its to much work. just take the relay and use some pliers to twist the prongs don't bend but twist so they are on a 30 degree angle then push it in. this will make a good connection forever. a little dielectric grease will also help the connection
