Here's the story. I got this car used, the previous owner has an aftermarket alarm system installed but I don't have the key fob. So I decided to take the alarm brain out cause it's hanging under the dash which is pretty annoying. I following all the wire and took it out. Electrical taped all the exposed wire. I tried to start it, it won't start. I check all the relays and narrowed down to the fuel pump is not getting power. I jumped the FUL/GRN in the diagnostic box to prime the fuel pump still heard nothing. The car will crank over but just getting no fuel at all. Also the cooling fan will come on whenever the key is in on position. Can anyone give me direction where and what should I look for? Thanks

Have you checked your fuses? go through and check them all, preferably with a test light.. chances are you have a blown fuse or hooked something up wrong. Alarm systems are fairly basic , just re-check you have hooked the cut wires back to correct colour/locations. Have you tryed bridging the actuall fuel pump relay pins?

Ok. i just checked the fuse, the fuel pump fuse is blown and I replaced it. now if i turn the key on, the fuel pump still not come on, I checked the relays, the circuit relay wouldn't engage. but if i jump the FUL/GRN in the diagnostic it engaged and i could hear the fuel pump running. Is that mean the ECU was not getting signal to start the car?

Did you go back and check the wiring you have repaired from the removal of alarm? Id really be re checking your work, making sure the correct colour wiring is going to where it should be (Might be worth while sourcing the wiring diagrams). Have you checked all fuses? Theres a few locations of where fuses are kept. Has the fuel pump fuse blown again? Re check.. Let me know what you find
