Ok let me simplify it I had a fuel line rubbing on the body changed the line and now truck won't start grinding from starter brake line literally lights on fire and is glowing red

SOURCE: truck won`t always start

Here are some things to try... First, make suire all battery and starter connections are secure; then if it won't crank, at the starter solenoid (on top of starter) there are two wires, the fat one providing the actual voltage that operates the motor, and the smaller wire that carries the starter actuation control voltage, when the key is turned to "Start". being very careful not to touch grounded metal, use an insulated pair of pliers or screwdriver to connect these two posts together, delivering the always present 12 volts direct from battery to the solenoid. If the starter is good, this should make it crank, indicating a problem further upstream in the crank circuit. If it doesn't crank, you have a bad starter... You can also check this with an inexpensive 12 V test light... ground the clip lead and hold the probe tip to the smaller terminal while having a helper turn the key... If the crank impulse is reaching the starter, the light will come on, and if the light is on but no cranking it is the starter.

If the crank impulse is not reaching the starter, it could be caused by any of the things in the start circuit. The voltage that is supposed to trigger the starter originates from the under dash fuse panel and goes through a kind of self resetting circuit breaker that can be tripped by excessive current heating a short length of resistance wire sufficiently to cause a bi-metal contact strip to curl away from its mating contact and breaking the start circuit... If your problem was heat related, I would suspect the breaker. From there the voltage goes through the ignition switch, and from the ignition switch it goes through a safety interlock circuit which is different for automatic and manual transmissions.

Automatics have "neutral safety" switches that break the circuit if the car is not in park or neutral, and this switch can either be under the shifter cover or built into the transmission. You can try jiggling the shifter while trying to crank; an intermittently faulty switch will usually show some effort to crank (possibly briefly) while doing this.

Manual Trannys have a switch that breaks the start circuit if the clutch pedal is not fully depressed, mounted under the dash in contact with the clutch pedal arm. Working the clutch pedal while holding the key in crank position might produce intermittent start efforts if this is the problem.

If you can locate whichever of these switches you have, you can also use the test light to (1) see if the start signal is coming out of the ignition switch and (2) going through the interlock switch.

You can also temporarily bypass these switches by shorting together or jumpering the two connectors on the switch.

I had a similar problem with my 1991 Prelude that ended up being the starter, and it was HUMIDITY related, of all things! I had driven through some high water by necessity, high enough that the starter was submerged, and then experienced your exact same symptoms... Showed up especially in humid, cold, or rainy weather, The water had washed dirt/sand into the solenoid engagement mechanism and had eroded lubricant, causing the solenoid to bind and not fully engage. Starter replacement solved the problem!

Hope this helps you get it fixed, but don't hesitate to post a comment or question if you need more help, and best of luck!

I have the same problem. it just wont start one morning. can you please help me in case you have solved your problem already.

SOURCE: 1997 F150 manifolds are glowing red

Sounds like cat convertors are clogged.

SOURCE: 1997 gmc 3500 box truck. no brake lights. changed

Check the fuse.

SOURCE: glow plug system will not cycle

Do you have dual fuel tanks? Place the return fuel line from the back of the fuel pump in a bucket and see if it will start. If yes replace the fuel tank switching valve. It may switch supply side ok, but not return side and if so it is plugging the return, which will cause a no start stuation. If it starts running the return line into a bucket replace the switching valve.
