ok, now my car just doesnt turn on, timing is correct, i have spark, fuel pressure is good, compression is there just wont start, i got codes 12 and 13 on ecu. I replaced both Engine temp sensor and the MAF and still get same codes, and engine still wont turn on, i dunno what else to do now.\

any help is appreciated,

thanks danny

If you know the sensor are good, then you need to check the wiring. Check the FAQ and get a copy of the FSM. That will give you instructions on how to check those sensors and their associated wiring.

i check the harness i had the plugs on the engine temp sensor on the ACC thing and it still wont start, the MAF was alright got 0 ohms from the wiring, can anyone explain how to delete codes from the ecu?

RTFSM. Or, look at the 240sx.org FAQ for how to clear the codes at least (same as SOHC KA), its real simple.

do i really have to crank it over fifty times?

[biosehnsucht]

eh, I should have been more specific. look for the topic on pulling/checking codes, involves messing w/ the adjustment screw on the ECU and going through mode 3 diag once, at least I think that clears the codes...

There is a link to the FSM in the FAQ. Please read through the FAQ and down load it. EVERYTHING you want to know is in that book.
