Heyo, my first post. I already know y'all aren't gonna "go easy on me" so I'm not gonna bother asking.

As the title says, I've got a crank but no start condition. Fuel pump primes on key turn, and fuel pressure going into the fuel rail is outstanding.

Previously installed (within the last 6 months)
-new fuel pump-new fuel main relay
1 CEL code-43 [fuel supply sys.]

Please note: the car ran and drove everywhere until I shut it off at Walgreens and upon attempting to start up again, it would just sit and crank, and crank... And crank....

When it WAS running and driving, recently developed an intermittent starting issue; I would have to crank it 2-3 times in 5-15 second intervals until the engine would eventually sputter to life with an (apparent) terrible misfire.

Starting with warm engine is always more successful!!

Thanks in advance!!

 

The code 43 is tricky, because it is very vague. I had this intermittently on my 95 accord and could never figure it out.

For a crank no-start, you need to determine if you are missing fuel or spark. Spark is easier to test, Just pull the spark plug boot on the spark plug wire. You can use an old spark plug, a spark tester, hold the boot near a metal bolt on the valve cover, or a timing light (plenty of youtube videos on testing for spark). Have an assistant try to start the car and see if you have a visible spark.

For fuel, you verified your pump is working and you have pressure at the fuel rail. You haven't verified the fuel injectors are opening. You can try removing the snorkel to the throttle body, have an assistant crank the engine while you spray starting fluid into the throttle body. If the engine fires up (even if poorly) while spraying starting fluid, then you have a fuel delivery problem to diagnose.

I'd start with spark as it is easier to test and typically more common of a problem vs fuel.
