SOURCE: fuel cut off switch for 1990/91 ford escort 1.9

The "inertia switch" which shuts off fuel to the engine in the event of a collision or jolt on a 1991 through 1996 models, as well as on 1998 coupes, is located in the rear of the vehicle, near the right (passenger's side) strut tower. On sedan and coupe models, open the trunk and remove the right-sided trim panel. On sedan and coupe models, open the trunk and remove the right-side trim panel. On hatchback and wagon models, there may be an access door secured by clips. On some models you may need to remove the lower quarter trim panel on the right side, however it is easier to cut an access hole directly above the switch.

SOURCE: Ford Escort 1998 fuel pump not working.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

SOURCE: 350 Chevy starter wiring diagram needed

IF YOU HAVE A POINTS TYPE DISTRIBUTER, THE WIRING WILL BE: TO ENERGIZE THE STARTER SOLENOID A LARGE, ABOUT A NUMBER 12 OR 14 GAUGE WIRE WILL GO TO THE INNER MOST SMALL TERMINAL ON THE STARTER SOLENOID. IT MAY BE PURPLE IN COLOR. THE SECOND SMALLER WIRE SHOULD GO TO THE OUTER SOLENOID TERMINAL AND GO FROM THERE TO THE + TERMINAL ON THE IGNITION COIL. THIS IS FOR BY PASSING THE RESISTOR WIRE FROM THE STARTER IGNITION SWITCH. THE LARGER BATTERY CABLE WILL GO TO THE UPPER TERMINAL ON THE STARTER SOLENOID. THERE MAY BE AN ADDITIONAL BATTERY FEED WIRE TAKE OFF FROM THE STARTER BATTERY TERMINAL POST ON THE SOLENOID FOR OTHER ACCESSORIES. THIS TYPE OF SYSTEM (POINTS TYPE) WAS TYPICALLY DONE AWAY WITH IN 1975 WHEN THE HEI DISTRIBUTOR CAME OUT.

SOURCE: need wiring diagram

Go to autozone.com and register they have good wiring diagrams for your truck.What I saw was all the relays going to ground so you should have 12V coming off the ignition switch.

Need the wiring diagram for 2005 Chevy trailblazer underhood fuse block, starting circuit.


Do you know if it is ECM/PCM or BCM controlled ?
Circuit Description (ECM/PCM Controlled)
Moving the ignition switch to the START position sends a 12-volt signal to the engine control module (ECM)/powertrain control module (PCM) Crank Request circuit. The ECM/PCM verifies that the transmission is in the PARK or NEUTRAL position. With the transmission in Park, voltage flows through the Park/Neutral position switch and feeds the starter relay coil. The PCM then grounds the control circuit of the starter relay. When the starter relay is energized it allows battery positive voltage to the starter solenoid S terminal. On some vehicles the starter will continue to crank the engine with the key released until it starts or the crank command has timed out to prevent excessive heat build up in the starter circuitry or the ECM/PCM receives an engine run flag.
Circuit Description (BCM Controlled)
Moving the ignition to the START position signals the body control module (BCM) that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the powertrain control module (PCM) requesting engine start. The BCM also energizes the RUN/CRANK RELAY. When the RUN/CRANK RELAY switch side closes, and the vehicle is in Park or Neutral or with the clutch is fully depressed, if equipped, supplies voltage to the starter relay coil. The PCM verifies the transmission is in Park or Neutral and the clutch is fully depressed, if equipped. The PCM will then ground the control circuit of the starter relay, closing the switch supplying voltage to the starter solenoid. On some vehicles the starter will continue to crank the engine with the key released until it starts of the crank command has timed out to prevent excessive heat build up in the starter circuitry or the PCM receives an engine run flag.

Free wiring diagrams here
http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on engine ,then under subsystem click on starting . Click the search button ,then click the blue link .
If you look at the diagram you will see the ignition switch ,when in start it sends B+ voltage to the ECM/PCM or depending on which system or engine to the BCM . When it see's this input it will energize the starter relay located in the under hood fuse box. This happens if the control module in charge see's another input from the PNP- park neutral position sensor and if no anti-theft system problems .
Good luck !

2005 ford focus, the car will start and run for a few seconds then stop. The fuel pump does not come on


Are you missing anything else?
Engine cranking, do you have spark at the plugs and fuel injector pulse? The reason I ask, if your missing all three, have to check for rpm signal, comes from crank sensor.
As far as just the fuel pump, could be the pump--voltage and or ground circuit--could be problem with inertia switch--fuse.
Any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.
I don't think it is your security system, my info says your security system will disable starter motor among other components. Make sure battery has a full charge.

I have a 2007 dodge charger 3.5 liter.shut it off at gas station went to go start it and nothing, all gages and lights work but won't even crank over.. We have checked starter,all fuses and relays..


If the starter is accessible energising the solenoid with a jumper cable from a battery live will test the starter, the battery cables and connections. If the engine cranks all is well and the problem is then narrowed to the supply from the ignition starter switch to the solenoid; worn or faulty switch, bad connections, broken wire or possibly immobiliser problems.

It is worth noting on modern vehicles the starter wiring isn't as straightforward as it used to be and if your car uses the CAN-bus system or similar, turning the key to start the engine is only sending a signal to a black box or ECU instructing it to crank the engine. In this case such things as wiring diagrams, a code reader or scanner and some experience is essential.

Can somebody send me a wiring diagram


You may need to wire a switch to the cut out. Since you "eliminated" it, its not going to rev. You need a closed circuit and should be able to create one via a switch, however I recommend consulting a local mechanic or other Fixya expert for a second opinion.

Ignition switch


engine will not crank.
if it dont crank it can not start. nor sustain and run.
the first steps are:
1; check all fuses.
2: jump cable start engine, s
starts now, then the battery is weak ,dead or JUST discharged.

the battery must read 12.6vdc rested or its weak.

if jumper fails to start car.
we then hot wire the starter solenoid.
no crank now, the starter is bad
yes, cranks now, the key line is dead
see the 83 tricks here, for making it start.

Nissan maxima 3.5 2007wont start the key lights stay on


The most common cause of a non-starting car is the battery. It is either weak, (low voltage) dead, (zero voltage) or has bad connections. (corroded or loose) I will assume you have a fully charged battery with good connections. (both to battery and starter relay)
If you remove the starter switch lead (small wire) from the starter relay and apply +12v from the battery to its respective prong or lead on the relay, and your starter cranks, your starter switch is faulty. (not to be confused with your key switch). If you jump the two large wires together on the relay and it cranks, then the relay is faulty. If you jump the two large wires together and nothing happens, then starter is faulty, or wires to starter are loose or broken. Picture of starter switch prong on the relay is pictured. NOTE: sparks are to be expected, so don't be too scared
