One day my starter fuse blew at the gas station.
Wound up replacing the starter. Fuse still blew when I went to go crank the truck up. Ended up installing a push start ignition button. Ground to battery hot to starter solenoid on my starter. Try to start the truck. It wants to turn over. But it will not crank up. Before I installed the push start ignition button. I tried wrapping wire around a blown fuse and starting it a couple of times and like a moth to a flame i tired cranking it up that way a few tikes with no luck. After trying and giving up noticed one of my coil packs connector began to melt. Replaced only that one because when I barely pulled on it, all the wires came loose. But the other still seems to be intact.

MY fuel pump works and I have fuel pressure going to my fuel rail. My alternator is fine. My battery reads 12.38 volts.
Only thing I can think is the sparkplugs are bad but they look fine also.

Anybody possibly know why my truck isn't starting up???

 

Are you able to rotate the engine clockwise using a big socket on the crankshaft pulley bolt when in neutral???

 

Haven't checked that yet but gonna check that now and update

 

Just checked and it feels normal turns clock wise

 

OK, If you can rotate the engine clockwise 2 turns with a wrench, then next step is to make sure the starter can spin the engine at normal speed.

Once that's OK,spray some aerosol starting fluid into the air cleaner or throttle body, try to start, do this a few times. If it runs for a few seconds then quits out, you have a fuel delivery issue, start there. If it won't run at all when you do this, then it's a spark issue, work on that. This is a common first test to help isolate the problem when the engine spins/cranks. And remember: just because the engine can crank fine, doesn't mean that the electrical part of the ignition switch (the "run" circuit) is OK.

 

​​​​​​Installed new coil packs and press start button.Only thing I'm gonna do now is install new spark plugs. If it don't crank up then I'm gonna hook up an obd2 tester to it. Fuel pressure and fuel pump is good. Checked it at the fuel rail it gets pressure. Not enough to make it squirt out super hard, just enough for it to come out tho. I'll check again just to be sure. Spark plug wires are good. Mass airflow is good so is wire connector. I have to wait untill tomorrow to get new spark plugs. Hopefully the obd2 tester tells me the real true problem tho. When I put the new coil packs on. The engine makes this intermittent jump every few seconds that it wasn't doing before. I assume this is the engine trying to do it's work to turn on. Maybe it's just not getting enough spark idk.

 

Before you go buy more parts.......did you try to squirt some gas or starting fluid into the throttle body yet? On a fuel injected engine, the intake hose needs to be reconnected before you try to start it. Do you have any pictures that you can attach of the engine as it sits right now?

 

No But here's everything I've "fixed"
Starter connection. Coil packs. All fuses. Fuel going through field rods and fuel squirts from field rail tester nipple.
Before all of this happen the anti lock brake system light and check engine light was on.
I won't be able to try and spray starter fluid into my intake until tomorrow morning.also for some reason both my new obd2 sensors are acting weird the bluetooth one wont connect to the ecu and new wired tester from Amazon just gives me code p0001 and won't let me do anything else only let's me read that it has this code. Maybe my computer is bad???? I was just told on the phone spark plugs don't go bad the way I'm suspecting they are.

 

Attached 3 pictures one of the computer. 2 of the engine

 

So....at this time......have you determined if the issue is SPARK RELATED.......or FUEL RELATED????
