Angry Giving Up HopeHey guys I am giving up hope for my 2000 F350 I purchased it in 2010 for too much money but it was fully loaded for its day it has every option available and the former owner also upgraded to a over/under overdrive transmission, and boy can she pull with a six speed transmission. The only thing that I have added to the truck was 19.5 rims and a edge performance chip. The former owner had already added the performance exhaust, intercooler, and intake. When I purchased the truck it had 92.000 miles and I had 8 wonderful trouble free years and put 40000 miles on the truck and then it happened. This truck is used to only pull my trailer and boat I went to gas up the truck for a trip stopped at a gas station gas up got back in truck turned key and ''Nothing" I had everything electrical working light, radio, windows, fans, everything worked except when you turn the key nothing happened the starter didn't nothing clicked the truck didn't attempt to turn over nothing. Called tow truck took three hours to show up turn key in truck to turn wheels and the truck started up like normal. I had the town truck driver take it to my local dealer to get looked over and they said that the truck had a bad starter which they replaced for close to 600 dollars. Drove truck home parked it thinking everything was okay until I went to use it a month later on a trip with my trailer and was 200 miles from home we stopped to eat got back in truck and again nothing all electrical items everything worked but not a sound or attempt from the starter. Had the truck towed to the closest shop and explained to the mechanic what happened and what was done to the truck. They kept the truck for 4 hours and said that I had a bad ground which they replaced for $350. We got to the camp ground no problems turned truck off went to start to move trailer and again nothing would not start or turn over now I was pissed and mad so we went to bed got up the next morning and tried to start truck and it cranked right up like nothing was wrong. Now I am confused as to what was going on with the truck. We packed headed back home and stopped for lunch went back to truck and again nothing no start nothing. We called a tow truck and before he got there which was about 2 1/2 hours later I just tried to start truck and it cranked right up like nothing was wrong now I am mad and confused. Drove the truck home took it back to the dealer the next day truck started up no problem at all. I explained to the dealership what was going on we went out to the truck and guess what no start no nothing but again everything electrical working. They kept the truck for 5 business days had me come pick it up and I was told that it had a bad oil pressure switch and when the truck warmed up that the switch was not allowing the starter to engage. They charged me $28 for the part and $1300 in diagnostic fees for that repair. I was mad but that was okay as long as it was fixed. The next time i used the truck was three months later tow my boat we stopped for gas and guess what no start no nothing again. Now I am really pissed so I left the truck sitting at the pumps while people were curssing me for blocking the pumps for a couple of hours and I turned the key and the truck started up like nothing was wrong. We took the boat to the lake and left the truck running for a few hours I was too scared to turn it off and have it not start again. Took the truck to a different dealership in the next town where I was told by Ford there was a expert 7.3 mechanic working that can diagnosed any problem with a 7.3. Took it there left it for 3 days I was called to pick it up and was told that it was fixed the mechanic took me out to the truck and told me that the truck had a bad relay and when it get hot it was not completing the circuit for the starter to engage. Well $945 later drove it home and turned the truck off tried to turn it back on and you know it will not crank nothing but again everything electrical in the truck was working. Called the dealership back to complain and I was told that they were not going to refund my money because according to the computer I did have a bad relay so they did not own me a refund. To make the story short I went out a purchase a Chevy 3500 durmax to tow my toys because I am fully frustrated with not be able to find anyone or dealership to fix my 7.3 that I love. So over the last three years I have only put 600 miles on it I only drive it places where I can leave it running or I know that I will be there longer than 3 hour. 3 hours seem to be the magic number of letting the engine cool down because I have now learned that the truck will only not start if it is hot or just been turned off. I have to let the engine cool down and it will start right up. If anyone knows a trick or have heard of anything like this happening to a 7.3 please, please drop me a line on how to fix this problem I want my 7.3 back on the road and I want to have trust that it will start up. HELP GUYS I am tired of the Chevy


I NEED MY 7.3 BACK!!!

 

Check the tin nut on the back of the IPR, may be loose or missing. Then pull it off and ohm out the solenoid coil, should be approx 10-11 ohms.

Or put it up on Craigslist, you'll get $20k for it even with this issue.

 

I would start with replacing the cheapo starter solenoid on the passenger side fender behind the battery.

Throw a voltmeter in the cab with you, see if you can get the truck to no start. When it happens put test and see if the small wires on the starter solenoid is giving the solenoid power? while someone turns the key to start position.
If not, leave the ignition on and jump the terminals on the solenoid and see if it starts as i describe below. \

I could not find a good video on this so these two will have to suffice
The if the solenoid is bad because its hot, youl know if you jump the large terminal with battery power to the small one and nothing happens. you can take a pair pliers or whatever and jump the two large terminals and ill bet it starts. probably your solenoid like the guys are saying. Be .a good time to replace with a trombetta

You can also use this , look for this small connector and put power to it, but im pretty sure it just jumps power to the small solenoid wire so if solenoid is bad it still wont start.

 

Another possible culprit, but less likely intermittent likely then the starter solenoid, would be a bad connection of your clutch pedel position switch

 

Mm-hmm. Check the battery cable connection to it also. I had a jury rigged up positive cable mess that was causing an intermittent no-crank. Loose connection at the passenger side battery + terminal to the fender relay.

 

Are those direct bolt-on 19.5's or did you use an adapter plate?

 

Most starters suck these days. We don’t call it a ‘stealership’ for no reason. I don’t know how those people sleep at night.

I hate that you are upset with your truck due to the incompetence of *******s that charged you waaaaaaaay too much money for crappy parts and service. This problem (incompetence) will be the death of the 7.3 as people who don’t work on their own trucks are turned off by experiences like yours.

Next time you have an issue, verify the small wire to starter is getting 12v when key is turned to ‘start’ and replace the starter if it is.

This is hands down the best starter you can buy for this truck.

If it happens again dump ice on the IPR, or turn a can of computer duster air upside down and blast the IPR. If it starts after you do that the IPR is bad and needs replaced

 

Even if the ipr is sticking, truck should still crank, just not start right? He doesnt even have crank

 

Correct, my bad. Shouldn't post b4 caffeine

 

Good point, and the cable can corrode and cause really high resistance, even if the connections are good.

I bet it's your battery cables. I would replace them. If they get hot when attempting to start you know they are bad, and since you own a boat you most likely have corroded grounds on the truck.

 

Sorry, I could not concentrate without a break in the text.

Every once in a while hit "enter."

 

In a nutshell a whole bunch of whining and a **** ton of money spent without fixing the problem. Poor diagnosis and likely ****ty parts installed chasing the problem that was created by ****ty parts.

This dude is lucky he ended up here!! If he’s willing to sift through a little advice, we’ll help him fix his problems and hopefully save him enough money to get a better chip/tunes.
