'89-740 (8 valve) No Start
1989 - 740 B230 (8 valve) cranking over but not firing/starting:
-Fuel 1. Fuel in tank, oil in donk, new radiator, 360k on clock. Revs been indecisive lately 2. New fuel filter 3. In-tank fuel pump used replacement (multi-meter saying OK) 4. Main fuel pump used replacement (whirring sound when ignition turned on) 5. Minimal grit in tank -Electrics 6. All fuses OK 7. Fuel injection relay used replacement (clicking) 8. Radio suppression relay used replacement (clicking) 9. ECU problematic 02800 000-561 used replacement (951 came out, will put back in) 10. Getting spark -fairly new plugs (bit sooty but not wet) 11. MAF sensor cleaned 12. TDC sensor ragged tidied up (sits almost directly down from rear of tappet cover) -Maybe 13. The Haynes manual talks about engine speed sensor (havent found this one yet, only TDC) 14. Haven't checked distributor area yet Car is on street other side of town. Any advice/suggestions greatly appreciated Last edited by Volvoaus; Jul 25th, 2020 at 04:26. |
