Electrical problem with a 96 ford probe se 4 cyl. 30 amp fuel pump fuse blew, replaced it and kept driving. about two weeks later it blew again, so I replaced it, and this time It blew cranking over, so I put in a 40 amp fuse and it blew cranking over, so I put a 60 in just to get me off of the freeway. drove it on the 60 for about ten minutes and shut it off.... about 8 hours later I put in a 40, and drove it for about 25 minutes where it shut off again, no blown f/p fuse this time and now my f/p doesn't prime when the car is in the ON position... i swaped out the fuel pump, still doesn't work, so i jumped the fuel pump relay (labled main circuit relay nf02) the fuel pump works and i have fuel pressure all the way to the rail, but it just turns over with no start. i have tried 4 other relays, and with the relay in, the fuel pump doesn't work. however whenever i jump the relay, the fuel pump does work, yet it still wont start... im wondering if this relay is connected to something else maybe, but i cant find anything online, any help please?

More than likely its being caused by a short-circuit to ground in the wiring in your Cranking Circuit.

If it blows the fuse immediately after installing the fuse, its probably a hot-wire. If it blows it the second you try to crank it over, its probably one of the wires between your ignition and the Starter Relay.

To track down the bad wire you'll need a Wiring Schematic for the vehicle and either a Digital Volt/Ohm-Meter or Test-Light and a basic understanding of wiring which is... honestly a little hard to explain over the internet. However, that is the only course that can be taken without taking the vehicle to a qualified Dealership Technician.

SOURCE: Fuel problems sensors or relays?

I realise timing is most important related to solving problem getting or keeping a vehicle running, but i just found this site looking for info myself. So if you've not resolved the issue i suggest changing the coil pack

remember the switch only gets power for 1 second when u turn the key on, the common problem is the ignition starter switch comes apart, it is located at top of the steering column near the bottom, drop the column down (2 nuts) and inspect the switch for separation.

check the pulse on the injector wire with a noid lite or a meter. If no flash then you most likely need a computer. Its called a quad driver in the PCM thats fried. You may have a shorted component that caused it to fail.

Since you say it will run if you add fuel manually I don't suspect the crank sensor because you have spark.

chec fuel pressure regulator it is in line of fuel next to engine-inpec for leaks insystem also-if u aquire a svc manual there is a list of codes or ask tech at dealer-look over ignition area to rule out
