That was quick reply.
I think those connections are ok. The engine turns over but does not ignite. No security system but the previous owner had some sort of machine in the cabin that fed off the battery at one time. I think the old connections are still there but the truck started fine for a couple years before this problem surfaced.

 

If your voltmeter is not a digital voltmeter we need to be careful where we use it. Did you check all the fuses? If you place the black voltmeter probe on a good ground on the engine,and the red probe on any one of the injector plugs most likely a red wire. With the key in the on position only you should read 12 volts. Do you have that?

 

i dont know which are the injector plugs. do you have a diagram by chance or point them out in the picture. how do i check the fuses in the engine compartment.

 

There are several videos on u tube that you should watch to get familiar with engine components and where they are located. The videos will save both of us a lot of time.

 

one thing to consider when disconnecting the battery that often is that you're wearing out the cables and the connections on the posts I suggest having a master switch put in to prevent that from happening. another thing that by disconnecting the battery it sounds like the pcm can't set and retain the memory of how you drive to give the best performance of the engine. I ain't trying to contradict Hanky in any way. and I don't know for sure if your engine has coil over plugs or not. that is for Hanky to tell me or not

 

i would like to watch those. how do i search for them or do you have a link.

 

Type in on Google
"How my fuel injected engine works"
There is so much information that will give you some understanding of what is there and a little info about how it works. You won't become an expert , but you will at least get an idea of what is where and what it does. I would only bore you where a video will help you.

 

ok. I have a pretty good idea of how the engine works but I think the plugs are hard to get to. Could we start with the fuses. How do I check the ones in the engine compartment.

 

All you need to do is have the voltmeter set to read in the 12 volt DC range.
Place the black test lead on any good ground then touch the red lead to each fuse. If it reads 12 volts on one side of the fuse it should read 12 volts on the other side also. There is also the fuse panel in the vehicle under the dash by the instrument cluster. You may need to remove a plastic panel cover to get to them. Some fuses will not read 12 volts unless the key is on. Once you try this you will see how easy it is to do.
I forgot to tell you if you come across a fuse that only reads 12 volts on one side of the fuse and not on the other,that fuse is no good.

 

well, all the fuses check ok.
excluding the black cubes in the hood fuse box, these have no terminals but are solid
