06’ 5.7 won’t crank

[BigRig84]

My dad’s 06’ 5.7 wont turn over.

We hear the click at the solenoid.

Battery is good

We jumped across the solenoid and it cranks but won’t start. Made sure the key was on

Fuel pump is kicking on, plus it was replaced a few months ago

Tried to clean the terminals on starter and broke the connector stud, so just put a new starter on and it’s doing the same thing

Ignition relay is good

All fuses that we know of are good

Thought it could be neutral safety switch, but backup lights work when we shift it in reverse

Tried to start in park and neutral and wiggled the shifter a bit

Thought maybe an anti theft device, but can’t find anything to check.

Would a crank position sensor keep it from cranking? I know they will keep it from sparking, but not sure about cranking.


Any help will be greatly appreciated! I feel bad for my dad. I gave him this one when I upgraded last year and he’s had nothing but problems with it.
A friend suggested this forum so hopefully one of you guys have an idea. Thanks!

Is it getting fuel can you hear the pump kick on, Do you have a spark, take a plug out and ground it to the block, on many if you don't have a spark it will shut off the pump, the fuel pump relay is under the fuse block, its called a TIPM (totally integrated power module), get back here if you need info on how to bypass the fuel pump relay or repair the TIPM.

Not cranking. I would say a bad connection somewhere. The fact its not cranking at all. Just clicks, wouldn't be a fuel pump issue. Or spark issue. Your positive cable goes straight to your starter. Then you have a solenoid, with a wire that goes to your key switch. When you turn your key, it sends power to the solenoid, bridgeing the gap, and powers the starter. When you bridge that gap, it wants to start. Because right now it's not even cranking. Just clicks. Take a voltmeter, have your dad turn the key, see if your getting 12V at the starter solenoid. Thats where I would start.( I'm thinking/ typing out loud. In the above sentences) im sure you already know most of all that. Hope that helps man. I'm also thinking old school. Everything probably, more then likely runs through that damn TIPM. you could even find the ignition wire running to the TIPM, and see if you have 12V when your dad turns the key? going into the TIPM and out. IF !! It runs through the TIPM. that I'm not 100% on. BUT!! you hear the click At the solenoid...so 12V is obviously present when you turn the key. I'd double check, make sure you have 12V. But I'm also confused, so it won't crank and won't start? It has to crank to start. Either make, or if you have one. Hook up a switch, that bypasses the key switch. One end to the postive, one to the starter solenoid. If this is the only way to crank the truck. Now give her a fuel source. Carb cleaner or starting fluid. See what she does. You might have to open the throttle body plate with your fingers, if you use carb cleaner or starting fluid. Again im thinking old school. Good ol cable, thats not present here.

Yeah it’s got us stumped! I think I’ll try what you said and check that it’s getting a full 12 volts at the solenoid. The crazy part is, when I jump over the solenoid, it will turn over, but not start. I think there’s some kind of safety or security feature that is engaged. But heck if I know where to find it.
Thanks for the tips!

Dang!! TIPMS are expensive. Didn't know you could buy them on a site like that. Thanks for posting that. I will keep that site in mind, if and when I have problems.

Thanks, I’m gonna check it for spark tomorrow. Is there a way to know for sure it’s the TIPM?

Tonight I was finally able to get it to start by jumping across the solenoid. On the solenoid control wire, I have 12 volts when the key is in start position. But when the wire is actually hooked to the solenoid, it goes to zero when the key is in the start position. If I remove the wire from the solenoid, while he key is on, I have 12 volts. Any ideas on that? Think it’s shorted out somewhere when you put it under load? I’m very confused on this one.

Most starters( all the ones I've worked on) ground to The Mating surface of where it's mounted. I see you replaced the starter, did you clean the mating surface before you put the new one on? That most likely isn't the issue but it's something to rule out. But it very well could be the problem

 

[Karlsweg]

Bad grounds. Clean them and mating surface with a scuff pad. Put white lithium grease on them afterwards. The main one is the block to battery ground. It probably is corroded in the casing. If you look close is the cable wires turning green? The ground straps on the back of the heads to cab are probably broken. I added extra ground wires to my 07 and haven’t had anymore problems like you are having.

 

[BigRig84]

For now I just have a push button hooked up so he can at least start it. I’m not sure where the problem is. I’ve been tracing wires all day and it all seems to be good. I did clean up the area where the starter mounts, as you suggested. I told him the push button was temporary, but it may become permanent lol.
Thanks

Heck, man! Maybe you can put holes in everything in front of the crankshaft bolt and make a handle to hand start the engine for tha model T experience! JUST KIDDING!

 

[BigRig84]

Lol yeah dad would probably like that

Just tell your dad you upgraded his truck. As long as his key is with him. He can start his truck. The whole " put the key in, and start it". That's a thing of the past. Haha haha good luck with your search man.

Lol thanks! Yeah I think the push button may become permanent on this lol.
