My car was vandalized. Thieves tried to to steal the car by taking out the aftermarket alarm system but fail. Left me with a mess and a car that doesnt start. I have a 1996 honda accord 5 speed 4 cyclinder. The car cranks fine but do not have any fuel pressure. The main fuel relay is brand new and hear is clicking. But i still have no fuel pressure. I tested the the fuel pump and it works perfectly fine but still installed a new one with no luck. Found out the the connector going into the fuel pump has no power some how. I have power going into the relay but not the pump. Couldnt figure that out so i hard wired the pump so i have pressure. With my luck found out my injectors are not working at all. (All 4) Now Im lost. Car cranks and has spark but nithing in the fuel system is working at all except the main relay.

 

Is you alarm system tied into the cars operation or just the doors. Seem to me it's the alarm that has cut power to fuel.

 

I was looking up aftermarket security and it seems like it does seem like it does control the fuel system but i dont see a whole lot of wires that were cut except on but thats for power. Because of that im kinda leaning away from the alarm being disabled being the cause

 

If your car was working prior to then I would completely check the alarm before moving on. Do you know the brand and model number. If so look it up to see the install instructions to verify everything is in place.

Being that you don't know what completely was cut im sure there is a wire you are over looking somewhere. Did they cut inside and under the hood?

 

I don't have a wiring diagram for 1996, but you might want to check the terminals at the main relay. Find out which blade of that main relay is supposed to become live; like key on or whatever.

When they cut wires, that might have blown a fuse somewhere, leaving some circuits without power. The main relay switches power to the ECU itself, and to the fuel pump. No power to the ECU would look just like injectors not working (depending on how you tested them).
