Fuse block broken in middle ford aspire cranks over but don't start

It's on the block but check by spraying fuel into the throttle body if it starts there's a fuel issue like the pump relay fuse if it doesn't start your idle air control valve or throttle position sensor maybe bad it's rare for the crank sensor but it's a 98 so 20 years old it could be but the other sensors mentioned are more common the crank sensor is a magnetic pulse but the sensors for idle and position have contacts inside that can become worn-out and break contact resulting in a no start condition

Make sure you're getting power to the fuel pump after start up. GM cars provide power to the electric fuel pump via the starting circuit when cranking and switch to alternator/battery power via the fuse block and 12v relay with ignition on in run position. Check your fuse block (bad fuse; power not getting to part of fuse block) and fuel pump relay. Could also be plugged fuel filter, bad pump or ?. but not likely because you get fuel while cranking. Check for error codes in the engine control computer (GM OBDII) as well but that probably won't show anything. Good luck and good hunting. I had a similar problem with a Chev Astro. Turned out to be power not getting to one bank of the fuse block because of a burned junction terminal buried behind the battery under the hood. Get out the multimeter and start looking for failed electrical components or broken wires.

Find and replace the ignition SWITCH, not just the key switch.On most cars it's down the steering colum actuated by a rod from the keyswitch. don-ohio

No spark or no gas. Are you sure the gas gauge acurrate? When you turn the ignition key from Off to Run, but not all the way to start, listen carefully for the sound of the fuel pump. If you don't hear anything, check the fuse. If the fuse is good the pump may be bad.

Remove a spark plug wire and hold the metal end close to [but not touching!] a metal ground [use a pair of insulated pliers to keep from possibly getting shocked. Have a helper crank the engine. If you see a spark, the ignition is probably ok, although that's not 100% certain, as the timing or dwell angle could still be off.

Good luck!

Please don't forget to rate! Thanks!

Relieving Fuel System Pressure

Locate the fuel pump relay in the engine compartment fuse block at location K4/C-1051. Remove the fuel pump relay. Start the engine and allow it to idle until it stalls. Crank the engine for 5 seconds to ensure fuel supply manifold pressure is released. When vehicle service is complete, reinstall the fuel pump relay and turn the ignition on to pressurize the fuel system. Start the vehicle and check the system for leaks.

Is it a gas engine? The crank sensor is in the block between the block and the a/c compressor. Did you plug it back in or did it get broken.

starter relay in fuse box

I had a similar problem and my shifter would not work until I got the electrical problem fixed. This was very frustrating, because I wanted to push it from the street to my garage and it obviously wouldn't roll if you can't get it to neutral. You may have a main fuse that is blown that is preventing the 12V current from reaching anything. There is also a fuseable link that is a small wire that is like a fuse that can also overheat and break connection. Your owners manual should show you the location of the main fuses. The fuseable links are usually on the front shock towers and each can be checked with a continuity tester. What you can do is get a good 12V test light and check how far the current travels starting from the positive battery terminal, until you find the problem. Check for breaks in wires and shorts. Since you know your battery is good, it has to be the wiring if its not making it to the fuse box. Just use the process of elimination to go one step at a time.

you hahe a short in the ecm/ecu

I have repaired many such issues on ford trucks, the column will have to be taken apart and inspected, there will be broken parts
