i have a 1991 Honda accord lx that i swaped in an f22a6
the main relay is good
fuses are good
ecu is good
gets spark
fuel pressure regulator is good
no disconnected grounds
it will start sometimes
when it does it runs for a minute
fuel pressure is 0 psi
when key is on when you crank it it stays at 45 psi
till i stop cranking and slowly goes down to 25 psi
cant figure out what is wrong please help

 

What do you mean by Fuel pressure is 0psi?

 

when i just turn the key to the on position it doesn't read any thing until i try to start it

 

could be a bad ignition control module

 

would that cause it to start for a minute then die?
could it also be the injector resister

 

never in my life ever heard of a resistor box going bad

a bad ignitor heats up and overheats which causes it to cut off

you can use this site as a guide to test your ignition system

thank you

 

why isn't anyone else concerned about the fact that there is 0psi fuel pressure on the ON position everyone else is talking about the igniter hahaha

 

because he said when key is on it goes to 45 psi .. but it is a bit ambiguous indeed

keep in mind the fuel pump only primes for a few seconds when you turn to the on position then it shuts off if not started will slowly bleed down to 0

 

well he didn't quite say what priming fuel pressure is or was, and i don't know who would post that they have 0psi after prime which is obvious right but either way there should be resting pressure

 

i got the car to run the idle was at 2000 rpm when i disconnect the iac it goes down to 1200 rpm
i adjusted the idle screw all the way in and then out a little and put an anothe iac now car will sty to run if i pump the cas till it dies and then restart it it runs with a high rpm and slowly drops down till it dies
