Question about Cars & Trucks
Check what the battery reads while starter is running.Or you can turn on the headlights and try to start it to see if the headlights dim or go out.
If so then the battery is too weak or has bad connections at battery or at the engine ground or starter solenoid.

Someone would need to check for power at the starter coming from the key switch. You could have a faulty neutral safety switch, key switch, or starter.

No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.---------
To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.--------
The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump. ----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Testimonial: "Thanks. That was the best answer yet.I didn't want to hear that the PCM might need to be replaced but the car has served it's purpose through the year"
Ever since I had mine, and when the previous owner did, had the same problem, except that this one hangs up. Sometimes it works, sometimes not. I thought it was a faulty mechanism as we fiddled with it and then it worked until the next time. Same thing. . It also could be a faulty electrical system. I needed a new alternator, since that resupplies the energy and if it's low then some things might not work so well. During rainy season I don't use it. I'm always afraid it will get stuck open and I end up with an unwanted shower.

Gm vehicles have had a ton of problems with the antitheft systems. When will turn the starter off when not functioning properly. http://vatspasslockpasskeysecurityhelp.yolasite.com/

do you have remote start on that truck? if you do, it has a hood safety switch that will keep it from starting if hood is open. That hood switch is quite easily identifyable. Look for it on the drivers side, either close to the firewall or right at the front of the fuse box.itsa worth taking a look
