Have 1983 dodge truck replaced motor truck started and ran orange wire on drivers fender burned into now truck starts but dies in 5 seconds or less any ideas?

Suspect throttle positioning sensor (TPS)...can be tested...need a meter set to read 5 volts DC...Tps is located on throttle body...it has a three wire connector with wire colors: Brown/Orange...Dark Blue/Dark Green...And Pink/Yellow...Engine off...Push points of safety pins deep into into rear of in place connector PLUS METER LEAD on Brown/Orange wire and NEGATIVE METER LEAD into DarkBlue/DarkGreen...Set meter to read 5 volts...Start engine...At idle (Yes, I know it is running rough) then read meter...RECORD READING...Next rev engine to full throttle...RECORD READING...First reading must be .08 volts...Second must be 4.5 volts...If second reading is less than 3 volts...example 2.4volts TPS is culprit...Replace TPS...all readings OK? Let me know...saailer

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

units that burn out have excessive current flowing through them. You had to replace the coil and the unit so I would check the voltage to the coil and the unit as it may need 7.5 volts input. This excessive voltage would result from a faulty resistor or shorted resistance wire to the coil or from the ECM.

Had a 89 cavalier did that start then die it map sensor. Also check ground wires if the become too corroded they won't start sometimes just run weird

You have a blown fuseable link under the hood. Look in the driver side you see wires wrapped up unwrap and check each wire. Replace blown wire and should fire up.

Sounds like fuel pressure you’ll have to check it to see you don’t have enough pressure it won’t start

gotta start with the color code of the wiring. verify that is correct first. you have to have fuel pressure for it to run obviously so make sure you wired it correctly. Here is the color code according to Mitchell OnDemand
black/orange= ground for fuel pump
orange/red=power on for fuel pump(only gets triggered from fuel pump relay)
dark blue/white= signal to pcm for fuel level
dark blue/ dark green= ref voltage

If that is ok then check for relay activation. Fuse 17 is the power source for that relay. If you have a good fuse but no relay activation you could throw a relay at it but if that doesnt do it then its gotta go to a shop. But if you are curious....
Relay code
pin 30= hot at all times
pin 86= relay control trigger from the pcm
pin 85= hot in run or start
pin 87= power source to fuel pump.(i.e. orange/red wire)

the relay will have numbers on it designating the correct pins. Get that right first then move on to the next. I'll be here. Good luck!

After it dies, check the spark and make sure it is able to jump at least a 1/4 or better gap and has "snap" to it, not orange and "fluffy". Also if no spark, check the ignition box on the fender. Both coil and ign box can misbehave if they have an internal problem after they get hot. If you have a lean burn computer on the air cleaner tap on it lightly with a wrench etc. (sounds crude but it works) If the engine stutters or changes how it idles, the computer is bad. (one that old can be converted to older ignition system but check emissions regulations before doing that.
If ignition system is working, make sure that the carb is not flooding and that fuel pressure is around 5-7psi.at the carb inlet.

Check the firewall for a ballast resister. It's a little porcelain thing with either one blade connected wire or two on each side. Held to the firewall with one bolt in the center. Change that, and keep a spare on hand.

You replaced the starter, plugs, wires, coil, battery and distributor. That should take care of the spark and the start. My only other guess would be that it isn't getting fuel all the time? Could be a fuel filter or pump. Good luck.

wut engine does it have
