My 1G has been dead for over week now, and I'm still scratching my head as to what the fix is. Here is the situation:
- Its spark on all 4 plugs
- I replaced the 3 caps on the ECU. (Plus, its a next to new ECU)
- The Fuel control relay was tested and checks out fine
- The fuel pump is fine, and I can hear it when I crank the starter
- the CAS has not been touched
- brand new fuel filter (so I made sure it wasnt clogged.)
- new/ replaced idle speed screw. (and set it to approx. 750 RPMs at idle)
-The timing belt was recently done, but I checked the timing marks and ALL of them line up perfectly. (crankshaft pulley, oil pump pulley, cam sprockets, front balance shaft, and the hidden rear balance shaft.)
-Although I did notice that I have a strange cut in the timing belt itself, (Which means Ill be doing the timing belt job again.)
-Idle pulley, and tensioner pulley, automatic tensioner, and tensioner arm assembly was replaced.
-When I attempt to start it, it runs over but doesnt fire.
Also, the engine stopped working while I was driving on the freeway, and I noticed that the engine was making somewhat of a hissing sound, plus my Air/fuel ratio gauge was indicated it was running rich. (It was on the first green bar on rich side.)
-I had a check engine light when it died, but I didnt have enough time to get a code reader on it. And when I put the key in the On position, the C.E.L. does not light up anymore. (Considering the ECU is Programmed Read Only Memory P.R.O.M, it wont tell me what was going on.)
---So, if I am getting spark, then it must be a fuel problem. Is there another component in the fuel system schematics that I overlooked? Why would the engine die all of a sudden after operating fine for 13 miles? Fuel problem? Ignition? Timing? Faulty, or broken or leaky injectors?Although my A/F gauge said I was running RICH, just MOMENTS before it died. Could the engine be flooded with fuel?
Please help me with this process of elimination. Any help is appreciated.
And if you live in the Bay Area, in Northern CA, I will pay you if you come by and can figure out and fix the problem.
Thanks!
