Came home after a doctor's appointment and my car felt great. No engine lights or weird idling. When I got home i turned off as normal then came back out an hour later and the car wouldn't start. It cranks but won't turn, it sounds like it's 1 second from starting but won't.

It seems I have battey my lights and everything activates as normal. Even tried jumping with my jump pack but no luck. I haven't tried jumping from a car but I'm gonna charge my pack again and try as last ditch effort. That starter isn't making any weird noises and I haven't noticed anything with it so I don't think it's that.

I went to see if my spark plugs were getting a spark but when I popped off the coil pack in cylinder one the whole chamber was full of oil. Other chambers had a bit but no where close. So I changed my valve cover and sparks, still no go.

From there I tried changing my crank shaft sensor because I thought i put in a super cheap one but that wasn't the issue either.

My last ditch effort was something wrong with the fuel pump. I checked the 15a fuse, it was fine. Then I tried testing the fuse relay with my multimeter and it was fine as well. So I bought a new pump and popped it in. Still no luck, I hear it activating when I turn the key to the on position so I don't think that.

At this point I'm thinking it might be my timing chain but I hope not. Ordered a compression test kit and spark test kit showing up Tuesday, hoping the best. Any advice is appreciated thanks.

from my experience you might have a head gasket leak, I need a video to determine what is the exact reason tho, but if it was the head gasket you can remove the coils and the SP individually and crank the car to see if water comes out in one of them, if not perhaps it's the timing chain failure, the battery won't make the car start if it has an issue, the alternator would be a bad charge but won't affect the ignition operation, anywho check the gasket and update, if u can show a video that'll be great

The car has compression...Did the starter fluid in the manifold test and the car started....At this point had it towed to a diagnostic place and waiting to hear from them. I have a new battery in there. Will have a update as soon as I hear from them...

If it ran on starting fluid its definitely a fuel issue. Most likely a dead fuel pump.

Its in a diagnostic shop since Friday it is now Tuesday and they have no idea. The fuel pump runs outside the car. Once it goes back in the car for some reason it does not work...At this point I really have no idea.. Will post updates....

What year and engine do you have? I can lookup a wiring diagram for the fuel pump.

It's a 2.5L 4 cylinder 05 Altima. The shop I dropped it off told me that the pump operates outside of the car and that the connector gets a 12V reading. I honestly think the shop was as stumped as I am with the issue. I'm probably gonna tow it home tomorrow, since I've dropped it off Friday it sounds like they haven't learned anything I didn't know. Also fuel pressure reading was 5 psi I believe

I had the car towed to another shop because this so called diagnostic center is a joke. I cannot post the picture of how they had my car literally apart on the inside and how they left the engine..They are not professionals. They had my car for 6 days and could not give me a reason why the car was not starting. The mechanic at the new shop could not believe how they left the car to be towed in that condition. The car started at the new shop it was towed to. The mechanic told me he just turned the key and it started. I am hoping to find out from him exactly why my car was cranking but not starting. He is going to put everything back together . I will post a update as soon as I get my car back. When I find out the reason as to why the car was not starting. Hopefully it could help someone having the same issue. Just becareful who you trust your car with. Some shops are shady ASF..

For sure man, its shops like that who give all techinicians a bad name. That would infuriate me also with the car left in that state. Hope you can get a legit answer. My guess would be a voltage drop to pump so it doesn't operate properly in vehicle but it does out of vehicle or another wiring issue. Or it is working in the car and there's a clog in the fuel line not letting the fuel pressure reach the engine. Keep us updated.

Heres the diagram. Looks like the ECM grounds out the starter relay that's stored inside the IPDM to turn it on. The relay then sends power to the fuel pump on the black and yellow wire at pump pin 1. The condenser spliced into the fuel pump power circuit helps reduce electrical noise on the circuit to make it more stable. The black wire at pin 3 should have ground. Pretty simple setup.

The car is back together and working...Got it back...No idea what caused it. I wish I could definitely say what it was. The car starts right up..Thank you everyone for the help. I am definitely saving that information you gave me. It could of been sooner if I did not waste 6 days with the diagnostic center. So far the car is running ok...Thank You Again...😇
