ka disaster
ok ladies and gentlemen I have about lost it with my ka24de. I have a 93 240sx and it will not run. ran great and cranked it up after just moving it and ran for about 5 secs and died. I have fuel, fire,and it's in TIME. I changed the ecu, maf, dis, coil, even removed harness and checked connection. It does have a new fuel pump, filter, plugs, wires, dis. cap and rotor. please someone help I am stumped. thanks Lee

Re: ka disaster (drftrx21)
What does it do when you try to start it?
Broken down to the basics, you need Fuel, Air, compresion and spark at the right times and in the right portions.
You need to verify that you have spark by holding a plug agenst metal while cranking. Also check for wetness on the plug to show fuel is getting through the injectors.
Did you verify that you have fuel pressure? (Fuel Pressure Regulator?)
Can you run a compression check?
Does the car sound "right" when you try to star it or are there strange knocks and thumps etc?
Why did you replace all the parts you listed? What diagnostics lead you to replace them?
Sounds like throeing parts at it did not work and now you need to figure out what is really happening. Give us more info and we may be able to help.
