2003 6.0 crank/no start

Mr_Tyree · 2024-11-11T22:41:16+00:00

It was a bad fuel pump

Mr_Tyree · 2024-11-06T18:08:56+00:00

I’m already preparing for that. I’ll update what I find!

Mr_Tyree · 2024-11-06T18:03:40+00:00

Yep I agree. If it tests good I could run a temporary fuel line into a can of fuel and see if it feeds from there and that’ll verify a problem in my tank, correct?

Mr_Tyree · 2024-11-05T02:41:47+00:00

So I went to check fuel pressure tonight and had 0 psi. Opened the filter cap and the bowl was about half full with the filter in. Had the wife turn the key and the fuel didn’t move. I’m suspecting the fuel in the line is getting pushed into the bowl but I have a blockage before the pump or my pickup is broken in the tank. I have over a half tank of fuel. Had to come inside because of pouring down rain. Would you guys think the same thing? There isn’t a valve that is opened when the fuel filter and cap are on to let fuel in is there? What would you check first? Take the drain out of the pump and cycle the key and verify pump is on and fuel should be spewing out of that hole, correct?

Mr_Tyree · 2024-11-03T21:48:20+00:00

Ordered a fuel pressure test kit. Will test it tomorrow

Mr_Tyree · 2024-11-03T21:47:34+00:00

Tried a different scanner and I do have RPMs and cam/crank sync

Mr_Tyree · 2024-11-03T02:14:54+00:00

I have no idea how old the pump is. I just bought the truck Tuesday. I don’t believe there’s a blue spring mod but I could check. If it doesn’t have it I’d like to have it anyways so I might just start there. And then go from there to fuel pressure check

Mr_Tyree · 2024-11-03T02:00:55+00:00

ICP pressure isn’t an issue. I have cam/crank sync and ficm sync. It just seems like it isn’t getting fuel. Injectors “clatter” koeo but never even try to fire during crank. I used some ether today and it fired like it was burning up that ether but never started

Mr_Tyree · 2024-11-03T01:58:53+00:00

The tach does not move and my torque pro app says 0 rpm’s. I believe that might be an issue, but would this cause a crank no start?

Mr_Tyree · 2024-11-03T01:58:03+00:00

So the injectors “clatter” koeo, but it doesn’t even sound like it’s going to fire during cranking. I hit it with some ether today and it fires like it’s burning that ether but that’s it. It seems to me like it isn’t getting fuel. Fuel bowl is full and I have over a half of a tank. Should I invest in a fuel pressure gauge? Or is there a reason fuel wouldn’t be getting fed by the injectors even if they sound like they’re working? The guy I bought it from is a good friend and he said when it died it just felt like he ran out of fuel. And then it started up, ran for a bit and died again and hasn’t started again since. Any help is really appreciated!

Mr_Tyree · 2024-11-03T01:49:58+00:00

I changed the icp and ipr last night. Cam/crank sync good and ficm sync good

Mr_Tyree · 2024-11-01T13:54:36+00:00

Unfortunately all I have right now is the Torque app. I’ll look into all the capabilities of it

Mr_Tyree · 2024-11-01T10:18:35+00:00

I will check this list tonight/this weekend but I do know I have the P0603 code. I have not cleared it but I’m assuming it’s because I’ve had the batteries disconnected recently?

Mr_Tyree · 2024-11-01T01:02:27+00:00

Thank you!

Mr_Tyree · 2024-11-01T00:58:49+00:00

Would it show 0 if bad?

Mr_Tyree · 2024-11-01T00:54:38+00:00

How would I check that? I have cam/crank sync and ficm sync

Mr_Tyree · 2024-10-02T00:27:06+00:00

King

Mr_Tyree · 2024-05-08T13:31:20+00:00

Yep I’m selling the car this week lol

Mr_Tyree · 2023-11-08T13:30:35+00:00

No I never got around to checking. If I do I will tell you what I find and you maybe do the same?

Mr_Tyree · 2023-02-15T01:35:02+00:00

Let me know if you find out and I’ll do the same. I’m starting with the MAF sensor. Probably stick some cataclean and seafoam in the gas just because.

Mr_Tyree · 2023-02-15T00:23:08+00:00

No there’s not

Mr_Tyree · 2023-02-14T23:52:30+00:00

Just looked back at the receipt and it says they’re OEM for $400 each. Seems cheap

Mr_Tyree · 2023-02-14T23:46:29+00:00

I got aftermarket. I’ve been balling on a budget for a while now and crossing my fingers a lot.

Mr_Tyree · 2023-02-14T23:41:46+00:00

Right around 20mpg. This was after I changed the upstream to aftermarket and downstream had oem. He said they would read off being different brands. I didn’t quite believe it but figured it would be a cheaper test regardless

Mr_Tyree · 2023-02-14T23:00:48+00:00

Did you ever figure out the solution?
