I have a 1991 F150 that I just bought a few months back, after I drove it home turned it off I haven't been able to get it to start again. I have put a new batteries, new battery cables, a new starter, and checked all most all the fuses. the steering column has a lot of play but checking to see if anyone has nay ideas

 

Assuming it is getting plenty of air, do you have spark and fuel? What is the fuel pressure? Have you checked for KOEO fault codes?

 

Please clarify, is the problem that the engine won't spin over with the starter?

 

I have done what I said but that is it. I don't know anything about the mechanical workings of a truck, unless its below a 1973, thin I could work on it. My next step is to replace the entire steering column from what I have been reading this may fix it at least I hope

 

Don't just throw parts at it. You asked for help, so answer the above questions. Here' a link to a quality troubleshooting guide https://troubleshootmyvehicle.com/fo...t-a-no-start-1

Does the motor turn over when you try to start it, or just nothing, no crank, no click click, no nothing? When you turn the key part way do you hear the fuel pump run for a couple of seconds? You may have to open the door to hear it better.

 

No when I turn the key on all I get is nothing at all, well dome light come on but that's it

 

yes, when I turn the I get a loud buzzing from the fuel pump its loud for because I just got hearing aids. I have also started cleaning all the grounding spots that I can find

 

Could be the clutch or the park/neutral position switch. They're not supposed to start unless the clutch is in all the way, or the slushbox is in park/neutral. If it's automatic, make sure it's in park, and if that doesn't work, try neutral.

If you think the problem's in the switch, you can test this by jumpering the starter solenoid under the hood. If the switch or the wire to the solenoid is bad, jumping from the battery connection to the ignition switch post on the solenoid should spin the engine over. If the solenoid's bad, bridging the battery and starter connections on the solenoid with a big screwdriver will bypass the solenoid and power the starter directly (expect sparks and scorch marks on the screwdriver). If the key is on when you jump the solenoid, the engine should fire up, so make sure it's in park or out of gear before attempting this or you may end up chasing it down the street/running yourself over.

My dad's '87 had the same issue due to a bad clutch safety switch, and we started it with a jumper lead for a while (battery connection to ignition switch connection). Replacing the clutch switch would've fixed it, but so did cutting it out and splicing the wires together to bypass it entirely.

 

Thanks for the advice and help I had to order the safety switch, I walked through all the steps that you talked about because of an old 69 Ranger I had.
i miss that truck, I was always working on her but it was fun and I could walk without my cane then.

Thanks again

 

Have you tried starting it in neutral?
