Hi, I just bought a 95 accord ex 4 cylinder...to start my car i usually turn the key on to 2...then the car starts after 2 seconds of crank...well i have recently changed the fuel filter and also did the tune up for the car and checked the fuel pressure with a mechanic and it was at 26.5..and it suppose to be at 32..would you say 26.5 is ok?..i am not sure if i have to replace the distributor or the fuel pump...2) another problem is my heater only works on 1..when turn it 2,3,4 it doesn't work..3) when i start the car in the morning it makes a roar sound for 30 seconds...mechanice suggested it is one of the belt but dont know which one.... can someone help me on this pls

one of the best posts ever, of 4000. even EX model and dizzy maker.
my guess, is it passes a time 4 spark tests.
the 1st rule of all EFI systems is.
1: if the ECU even THINKS (sic) there is no spark it MUST cut fuel.
the ECU has 3 ways to find bad spark (not all ways)
A: spark read back signal dead. (dtc 8? or 15)
B: CMP dead,
C: CKP dead.
the ECU will in fact flash the codes out to tell you which of the 3 are dead, if dead. ever do that yet? (code 4,8,9, 15)? others?
this is called by me, "crash and burn logic", (EFI Rules)
So never ever, troubleshoot fuel loss. with out doing all the above first.
1988 to 2013 cars, all work the same.(EFI)
some cars only activate the fuel pump cranking and running.
that be rule 2:
the ECUis covered in the FSM>
here is a free FSM.
test for spark using a test spark plug x4 (and at coil if easy)
do the scan, of the ECU, the winky blinky test, using the JUMPER.
when number 1 is up all the way on compression stroke you are at TDC. put finger over number 1 plug hole and when you feel compression pushing out make sure cylinder is up all the way on that stoke,i usually use screwdriver to make sure it is up completely..DO this by turning crank with wrench and not by key switch because screwdriver could damage piston........
the car is not recognising the key and is actuating the ignition cutoff (it starts then stops running straight away)try the spare key,if thats okay then you need to get the car/keys recoded as sometimes they do lose the ability to be recognised.
94-97 accord have common issue on key ignition. Key ignition seems to corroded. Solution take it apart clean or best way is to replace it. I know because I have done it to 94 accord 4 cylinders, 95 accord 6 cylinders and 97 accord 4 cylinders.
Well you get the spare key from the Dealership ,wal mart or any other places were it has the facilities to program the keys for your car (inbuilt chip ) usually Honda can program the key with hand held device and they charge $100 or hour labor charge .........Hope this information help you .....
Check your compression. If you don't have a compression checker, take the plugs out, shoot a squirt of oil in each cylinder, replace plugs and crank engine. If engine starts, you are probably looking at a bad set of rings.
