Update re re re set the timing got it to start and rev when its cold runs rich as shiat but after it warms up with my foot to the floor it won't go above 600 rpms.
I have a 92 240sx hatch powered by a rebuilt KA24DE. It currently has 192xxx miles on the chassis and 12,900 on the rebuilt ka. Not bad considering it was my first rebuild and I have given the ol' girl hell since I've had her running. But as I continue to try and make her a better car and fix things as they break (as I break them) she spites me and something else breaks. Anyway that's between me and her. :whip:
Here's the symptoms: air fuel and spark... no start. Sometimes sputters at the beginning of start up but never catches. Got it to start twice once with maf once without but with many things changed between the two times one of which was a bad injector doughnut. Once w/maf accelerated perfect no misfires but had black smoke, decelled perfectly but with white/gray smoke and did not idle. W/o maf black smoke all the time sluggish accell and decell wouldn't go over 2500rpm (which I know is normal) still no idle.
Heres what I've tried:
Compression test 150 156 154 152 in that order from 1-4
Different working maf after repairing the wires
4 different ECTs
2 working ECUs and tried mine in a buddies car which fired up perfectly
New spark plug wires and plugs
Newer tested and working injectors and fuel rail no o-ring or doughnut leaks
Checked all vaccum caps and lines all 2 of them FPR and Break booster (EGR deleted)
2 tested distributors w/ newer cap and rotor set motor to TDC when installed
New battery
2 working coil assys
Tested the voltage at the various sensor plugs all w/in specs
Here's what happened... I was leaving for work and was on the on ramp for the highway when she started backfiring and sputtering :wtf: then the temp guage suddenly dropped to C then shot up to H :eek: so at that point I stopped shut her off and went under the hood anly to find my waterpump belt shredded and dangling by a few little strips of rubber. Then I noticed the maf wires had been stripped of insulation but not broken. I separated the wires from eachother so that they did not touch. I let her cool off for about 15 min spinning the water pump by hand. The temp dropped quickly. I just wanted to get her out of sight from the highway. So I backed her up the on ramp the longer she ran the worse she got but the temp guage never got back to H. When she died we were completely blocking the on ramp on a blind corner up hill and I could hear cars coming so I got out to push and couldn't push hard enough from the drivers door. So I cut the wheels the way I wanted her to go but my streatched tires caught the edge of the pavement tuning the wheels toward the ditch and away she went I dove through the window and grabbed the e brake only to slide another five feet down the deep ditch. I ended up walking back to my house and driving my truck to work. I work 3pm to 12am so after work in the dark I returned to my spiteful ditch diving car, pulled her out with the truck, changed the belt and after about 15 minutes of sputtering for half a second then dying only to sputter again and again... she started and I drove her home. She was spewing black smoke backfiring and wouldn't idle. I had to run a stop sign but I made it the 2.4 miles back home. Since then I've got her started 2 times after 5000 different combinations of sensors and whatnot switched swapped and unplugged. Nothing is consistant except that she will not start dispite having Air Fuel and Spark. I am almost ready to sell what I can and be done with this infernal machine. This is my last ditch (no punn intended) effort to save her. Any ideas will be appritiated.
