My car would no longer start, I went through trying to find out if it was fuel or spark?

I forgot to mention I tried starter fluid. I tested the green and white wire, and it does have 12 volts and yes, the engine sounds fine. Excuse the picture I misread your message.

Yes, after I replaced the crank sensor, I had tach signal again. I checked for spark at the coil, and it was firing. After that I used some starting fluid and it started to crank over but it took a while and it finally idled on its own. It now will start up, but it takes 3-4 seconds of cranking before it starts. It has always taken that long but I know that’s not normal for a fuel injected 4 cylinder. You can hear the pump prime, but I think the pump is possibly weak it is also pretty loud.

When removing the old fuel pump, I noticed that there looked like burns on the seat where the harness was, I checked the harness and couldn’t find any visible damage, so I continued on putting the new pump in. When I finished, I could hear the pump prime, but it still took 4-5 seconds to finally start. After it started, I let it run for about 5-10 minutes and it turned off on its own, I tried to turn the key and no start again, so I checked my fuse with a test light and it was still good. After that I turned, the key, and it primed again this time it started back up. I drove it around for about 15 minutes perfectly fine and parked it for the night. The next day I went out to start it and attempted to drive but when I was leaving it started to stall like I was running out of gas and shut off. I turned the key, and it turned right back on no problem and took it back home. But I’m still experiencing long cold starts, the pump has shut off twice at random and sometimes the pump will prime sometimes it won’t.

I replaced the relay, and it still is acting like it doesn’t have fuel pressure. The fuel pump primes more now but it is taking a little longer to start, sometimes it still won’t start at all.

Okay, I will do a pressure test but if it comes back good what should I be looking for? Also, if the pump is not making pressure and I replace it with another one and it still is doing the same, what should I look for then?

Fuel pressure was at 51 PSI, there were also 12 volts to the pump. I already bought a brand-new relay and put it in but instead this time it would prime almost every time. I noticed every time it would prime it would start up guaranteed even with a long start. But when it doesn’t prime it’s not going to turn on no matter how long you crank it for.

Only about 2-3 seconds and I was getting about 32 PSI when primed.

Yes, it was 31 PSI when I turned the key to prime but 51 PSI at idle.
