Hi Friends!

My 1989 240sx will not start. when I turn the key it turns over fast but will not start. I have tested for spark, I am getting spark, I checked the gas, 1/2 tank. I changed the fuel pump relay, that did not work. I noticed after trying to start it so many time I blew the fuel pump fuse two times. Or maybe that is something else. this morning I put the battery back in after I changed it and now it will not turn over without some help from my jump start battery pack. I only get a clicking sound now. the lights, horn ete. all work but it will not turn over anymore with the battery pack. The car has been down now for a month. I am open to try anything now.

P :confused: please help

ok well did you try replacing the starter? how about the alternator? maybe you battery connections arnt strong...do you have an erosion coming from the battery? just throwing some topics up...trying to help ya

Try wiggling the MAFS connector. Try wiggling all connectors for the injectors, coil, TPS, everything you see. Try and get some more readings on the conditions. After you try cranking it a few times, pull a spark plug and see if it has fuel on it. Turn it over for at least 10 seconds before checking. If it has no fuel, then you have a problem in your fuel system. Also turn the key to the "on" position and listen for the fuel pump. It should emit a faint humming noise. Post up after you try that stuff. Good luck.
