Two nights ago i was driving, came to a stop light and stopped. While sitting there all of a sudden my tach dropped and i feathered it back up, light turned green. I eased the clutch out and gave it gas and it died. Crunk it straight back up and gave it all she had. Shuddering, jerking back and forth, almost no power, i limped it to a gas station. First thing i checked was oil, and it was low. Filled back up and she ran much better, but not quite right. The next day was full of power dropping, engine stuttering almost but not quite to the point of the engine dieing. Since then i have changed the crankshaft position sensor, and yesterday, the fuel pump was howling like a dieing wookie, so i changed it. After the swap, crunk up for about 5 seconds, and now it refuses to crank. Put my hand on the fuel pump casing, turned the key and i can feel it come on, broke out the multimeter, 12v at the pump. The main relay 1 is less than two years old. Idk what is wrong. Any thoughts?

 

Those things will run with a partially blown head gasket , Is there white goop under the oil fill cap ?. Or the fuel pressure may be weak , it has to be 25 psi as I remember and check for good ground/solid wiring , new fuel pump may be junk ,, What do the plugs look like ?

 

Good points, and i have made progress. I think the head gasket is ruptured, i have air bubbles in the radiator, happened after something hit me and busted my radiator. Not immediately worried about that, air bubbles is the only oddity in there. Now i saw or read somewhere that the fuel line psi should be between 40-50 psi. I started pullin fuel lines and turnin the key and gettin nothing , till i took the breather off so i could get to the fuel rail hookup, removed that, stuck it in a bottle turned the key and got nothing. Back into the car i went. I should mention, before i applied JB weld to the top of the fuel armature, everytime i pulled the fuel line after the first time, there was no back pressure. So after the jb weld and fuel rail test, i pulled the fuel line off the pump. And gas poured out the line. So the line is at least trying to prime. With the line loose, i tuened the key and fuel came out the armature. Looked kinda weak for 40-50 psi, but i tried another thing. Im broke down in a parking lot btw. Whipped out my compressor for my tires duct taped an empty pen to the hose that came with it, connected hise to compressor, stuck pen firmly into hose at the fuel rail going to tank, and flipped the compressor on. Compressor built pressure, up to about 18 psi, and then dropped to 0 psi.line cleared. I was assuming there was a clog so dirt or whatever was gonna gonna come out. The line was clear and only gas came out. Anyone he reads this and tries....remember that, i had gas down inside where my electric linea plug up. No bueno. So the line wasnt clogged, the pump was working. The fuel filter. It is part of the armature.it is not serviceable. When it goes bad thats it. A way u can tell, when it starts to go bad, starts to clog, the plastic on top begins to bubble and crack out. So when it fully cracks, the tank doesnt pressurize correctly, and the engine seems to "loose power" and damn sure doesnt wanna crank. I slapped jb weld over the cracks, and thats when it started to try and prime. Thought about grabbing a saw and redneckin the **** out of it, but thought better. Currently waiting on the upper half if the armature to be delivered, till then, im stuck in a parking lot.

 

You may not be testing actual fuel lines , Sounds like you don't know what you are doing .Sorry to say

 

No, they are definitely fuel lines, especially the one coming directly from the pump, i appreciate the advice, but ive replaced this engine, personally rebuilt the transmission as well as rebuilt the front suspension, i trust myself to know the line running directly into the fuel rail is a fuel line

 

I had trouble with a fuel pump I " rebuilt " ie. I bought the motor only and had to take the pump apart t install it . Maybe check that or but a plug and play if you're not getting any fuel
