I have been having problem with my 7 for the past month. After tons of trouble shooting, I figured out that I wasn't getting fuel due to my fuel pump not coming on.

I decided to rewire my fuel pump with this...



I also installed a switch.

Shouldn't I hear the pump on with the switch on?

I prime the engine for a few seconds and starts up and dies...

I decide to test and bypass the relay. It starts up for a second and dies. I start it again and hold the gas pedal and runs until i let off the gas and dies again.

Any Ideas?

Thanks!

 

Possible the fuel pump itself is bad?

 

I hear it turn on when direct power source to it

 

Well if the engine keeps running if you keep your foot on the pedal..............then you know its not the fuel pump. So drop working on the fuel pump.

 

are your injectors working properly? Mainly your primary injectors.

 

From my test,them seems to work alright. I tested with a test light and it would blink rapidly and sounded okay when I used a long screwdriver.

Everything from the checkvalve and bov not being plugged into the back of the turbo inlet duct to rock hard bottom grommets on the fuel injectors leaking air to the brake booster feed nipple not connected to the brake booster to the air line on the oil injectors not being connected up to the nipples on the upper intake manifold not conencted up right on the front and rear of said intake manifold to the vacuum rack pipes not connected up right to the fpr solenoid feed on the inside of the intake manifold not connected up to the vacuum rack pipes to..............the timing not being right (with the marks on the pulley aligned if you look in the top of the CAS under it's flat black top, the guts should look EXACTLY like the were before you stabbed the CAS............to a lot of other things being not right.
