OK thanks I just ordered the testers they'll be here in a few days and I want to make sure it runs before I put all that stuff back together again

 

p.s my battery is at almost 13 V

 

Cool just keep it charged up if you need to crank the engine over a lot.

 

sorry 13.27 volts

 

thanks for your help I'll keep you updated

 

and btw The crankshaft hub was rubbing the crank sensor and Rubbed a groove in it that's probably why it burnt I wish I can send you pics of my phone here I can't figure how to do it

 

Ok why was the harmonic balancer grinding on the sensor?

 

Wait a minute how is your battery at 13 .27 volts with no charging system?

At rest or after cranking like you have been doing it should be much lower.

Has it been on a charger?

 

good question I haven't figured it out yet maybe I need to Sand on it a little bit and it had some nicks in it from whoever worked on it previous

 

yes

 

Make sure the harmonic balancer is intact and has no play in it also inspect the metal plate that the sensor detects and make sure it is not bent.

If the balancer is ok there is a good possibility of a bad thrust bearing in the engine.

This would allow the crankshaft to move in and out of the block, if it has enough play in it your sensor could get damaged from this bad bearing.

Here is how you check it, but you may need to remove the timing belt to really see how much play the bearing really has.

But if the bearing is that bad that it damaged the sensor I imagine it should be easy to detect the play even with the belt on.

 

oh heck now I'm getting worried I checked it it moves a hair like that 30 seconds of an inch

 

possibly at the most a 16th of an inch but I can't even really see it moving but I can Feel it slightly go back and forth

 

would it hurt anything if I took my grinder and smooth the edges a little bit on it

 

The balancer that is someone took a chisel and made like five notches in it for some reason plus the front edge of it might be a little rough

 

Do not freak out just yet, face it you have a older truck with a engine that has racked up some miles crankshaft end play is normal to an extent.

There are specifications for each engine that shows the desired tolerance.

For now at least you may know what destroyed the crank sensor.

But all of this is just a hypothesis for now.

For all we know the play your feeling is within specification.

please do not start grinding on anything.

there are still many thing we do not know.

While your looking at the sensor and balancer in your opionion if the crankshaft moved forward further than it does now could the balancer impact the sensor in the same spot that it did last time?

If your answer is yes I would suggest getting the engine timing marks aligned then remove the balancer and timing belt and reinstall the harmonic balancer bolt so you have something to grab a hold of, and measure the amount of end play with a presision instrument to get an exact reading.

But even before you do that think about what happened when the sensor went out and what you were doing and how you were driving the truck.

Were you driving the truck aggressively or doing anything out of the ordinary like accidentally shift from 5 th gear to 2nd or pulling a heavy load ?

If you did something unusual you may get more time out of the engine by changing your driving habits.

I say this beacuse crankshaft end play does not happen over night, it could have been slightly grinding away on the sensor every once in a while for a long time but one event could have made it dig in deeper and finished it off if that makes sense.

Anyways for now just let us know if when the harmonic balancer is at its closest position to the sensor if it could make contact just like last time in the same spot from crank shaft end play.

It would be nice to see some pictures of the old sensor and the balancer.

I suggest logging on with a computer and not a phone if that makes it easier for you to upload pictures.

 

it doesn't seem that it would even get close to doing what it did I have no clue maybe something got in behind between the Sensor I will check it tomorrow for sure if I don't have to work the person whose truck it was she drove it like a grandma and it just died at a red light and she always had the olil change and took really good care of it

 

How about giving us more back ground on this truck.

How long have you owned it? Did it stop running while you owned it or did it die on the previous owner?

 

had it a couple weeks It was DOA

 

It died at a red light on her

 

The mother said she never drove it hard enough shifted before it was time etc.

 

Thanks for sharing this information, just know for the future when we try and help online it is difficult.

In our heads unless you tell us differently we think you have owned the truck all along and it stopped working.

When we are dealing with a vehicle that was purchase DOA and has been sitting possibly a long time we may give different advice or more advice depending on the situation.

Now I have to ask how long has this truck been sitting not running?

Is the fuel in the tank old and nasty?

Did you clean the tank when installing the new pump?

Did you even inspect the inside of the tank for debris?

 

yes I cleaned out the tank the truck probably sat for two months not running I did poor a few gallons of the original gas back in it it looked clean maybe a little extra yellow i'm thinking now to drain it and put fresh gas in it but a lot of gas around here has water in it from Harvey I live in a country so no stores close around here

 

A few months of sitting will not hurt the fuel, you would know by the varnish smell if the fuel was too old.

I just wanted to make sure the tank was not full of nasty old fuel and or debris.

 

yes it probably had 3 gallons in it and I added 2 fresh gallons to it
